Google Antigravity Review 2026: Why Pay $200 for Claude Opus 4.6 When It’s Free Here?

🆕 Latest Update (March 7, 2026): Antigravity reaches version 1.20.3 with a critical token accounting fix that was causing conversations to hit context limits prematurely — partially addressing the longstanding context window complaints. New since our last update: macOS sandbox for terminal commands (prevents accidental file deletion), AGENTS.md support for cross-tool rule sharing, artifact download support, and Google AI Studio integration is now live. Warning: A new rate limit crisis has emerged — Pro subscribers report 7-day lockouts instead of the advertised 5-hour refresh, even with low usage.

Reading time: 14 minutes | Last Updated: March 7, 2026 | Version: 1.20.3 Public Preview

The Bottom Line

Google Antigravity launched November 18, 2025, and remains completely free during public preview, but the honeymoon phase has definitively ended. This agent-first IDE gives you access to Claude Opus 4.6 (Thinking), the industry-leading model that costs $100-200/month through Claude Code, completely free. The Agent Skills feature transforms the generalist Gemini model into a specialist for your specific workflows.

The model lineup includes Gemini 3.1 Pro (High/Low variants), Gemini 3 Flash for faster responses, Claude Sonnet 4.6 with Thinking mode, Claude Opus 4.6 (Thinking), and GPT-OSS 120B. Antigravity runs multiple agents in parallel, tests web apps in a real browser, and generates visual artifacts showing exactly what it’s doing.

The catch: Community sentiment has sharply declined since launch. Users report context window issues (partially addressed in v1.20.3), a severe rate limit crisis where Pro subscribers hit 7-day lockouts instead of the promised 5-hour refresh, and what some call a “lobotomized” version of Gemini 3 Pro. One Reddit user called it “the most promising and most frustrating editor I’ve ever used.”

Best for: Developers who want access to top-tier AI models without paying $20-200/month, and early adopters comfortable with rough edges. Skip if: You need production-ready stability or rely on daily uninterrupted AI coding sessions.

🆕 What’s New: March 2026 (Version 1.20.3)

Since our February 12 review, Google has continued shipping updates to Antigravity. Here’s everything new through version 1.20.3 (March 5, 2026):

All Updates Since February 12, 2026:

• Google AI Studio Integration: Now live (launched February 2026). Design and test prompts in AI Studio, then execute them directly in Antigravity workflows.
• Secure Mode: Three terminal permission levels (Turbo, Auto, Off/Manual) for enhanced security. Prevents autonomous execution of potentially dangerous commands.
• macOS Sandbox (Feb 23, 2026): macOS users can now execute agent terminal commands within a sandbox environment to prevent accidental file damage outside the workspace. A direct response to the drive-deletion incident.
• Artifact Download Support (Feb 19, 2026): Agents can now generate downloadable artifacts — task plans, implementation summaries, and browser recordings — that you can save and share.
• New Settings Screens (Feb 19, 2026): Dedicated settings screens for model selection and terminal integration, making it easier to configure Antigravity’s behavior per project.
• Gemini 3 Flash: Lightweight model option, reported 3x faster than Gemini 2.5 Pro for quick iterations and simple tasks.
• Claude Model Upgrades: Claude Sonnet 4.5 and Claude Opus 4.5 have been upgraded to Claude Sonnet 4.6 and Claude Opus 4.6 in the model lineup.
• Google Workspace Support: AI Ultra for Business subscribers now get higher, more frequently refreshed rate limits.
• MCP Tool Support: Model Context Protocol integration for connecting agents to external services like GitHub, databases, and APIs.
• Account Remediation Process: Google introduced a formal process for accounts suspended under Terms of Service violations — a sign the platform is maturing its trust and safety operations.

🚀 What Antigravity Actually Does (Not What Google Claims)

Antigravity is Google’s agent-first IDE built on VS Code’s foundation. But calling it “just another VS Code fork” misses the point entirely. Here’s what makes it fundamentally different:

The Core Shift: Traditional AI coding tools (Copilot, basic Cursor, Windsurf) help you write code faster. Antigravity helps you delegate coding tasks entirely. Think of it as the difference between having a spell-checker and having a ghostwriter.

When you open Antigravity, you’re greeted by the Agent Manager, not a code editor. This isn’t an accident. Google designed it so you dispatch tasks (“Build a user authentication system with OAuth 2.0”) and let AI agents handle the implementation while you review their work.

What This Looks Like in Practice

I gave Antigravity a real challenge: “Build a clone of Insaniquarium, a simulation where you drop food, fish eat it, and they drop coins.”

The result? It one-shot it. First try. It built a working game using Phaser. But here’s the wild part: it didn’t just write code. The agent realized “I need sprites for this,” paused, generated fish and coin images using its internal image generation model, and injected them into the game code. Were they perfect? No, the fish had white backgrounds instead of transparent ones. But when I said “Fix the transparency,” it regenerated the assets and updated the code automatically.

This is the “agent-first” distinction. It’s not a chatbot. It’s a worker with access to tools: an image generator, a file system, a browser, a terminal. Compare this with what Claude Agent Teams offers for multi-agent coordination — Antigravity’s strength is the fully integrated IDE context.

⚡ Getting Started: Your First 15 Minutes

Getting Antigravity running is straightforward, but there are a few requirements that might trip you up:

System Requirements

• Windows: Windows 10 (64-bit) or later, x64 or ARM64
• macOS: Monterey (12) or later, Apple Silicon or Intel
• Linux: Ubuntu 20.04+, Debian 10+, Fedora 36+, RHEL 8+ (glibc >= 2.28, glibcxx >= 3.4.25)
• RAM: 8GB minimum, 16GB recommended
• Required: Personal Gmail account OR Google Workspace with AI Ultra Access add-on
• Required: Chrome browser (for browser testing features)

Installation Steps

Step 1: Download

Visit antigravity.google/download and select your operating system. The download is approximately 300-400MB.

Step 2: Install and Launch

Run the installer. On first launch, you’ll be asked to import settings from VS Code or Cursor (optional), choose a theme, and configure agent permissions.

Step 3: Configure Agent Permissions (Important!)

Antigravity asks you: “Who is driving the car?” Your options:

• Agent-driven development: “Autopilot.” The AI writes code, creates files, and runs commands automatically.
• Review-driven development (Recommended): The AI asks permission before almost any action.
• Agent-assisted development: You stay in control, but safe automations happen automatically.

Step 4: Configure Secure Mode

Secure Mode provides three terminal permission levels:

• Turbo Mode: Focuses on speed with minimal security oversight. Use for low-risk, sandboxed projects.
• Auto Mode: Balances efficiency and security. Recommended for most users.
• Off/Manual Mode: Requires confirmation for every terminal command. Safest but slowest.

macOS users: The new sandbox feature (added February 23, 2026) automatically restricts terminal commands to the workspace directory, preventing accidental file damage elsewhere on your system.

Step 5: Sign In with Google

Sign in with a personal Gmail account or a Google Workspace account with AI Ultra Access. Family members over 18 on Google One family plans can also access it.

Step 6: Select Your Model

Antigravity offers an impressive model lineup as of March 2026:

• Gemini 3.1 Pro (High) – Maximum quality, best for complex tasks
• Gemini 3.1 Pro (Low) – Faster responses, good for simpler tasks
• Gemini 3 Flash – Lightweight and fast for quick iterations
• Claude Sonnet 4.6 – Anthropic’s workhorse model
• Claude Sonnet 4.6 (Thinking) – Extended reasoning mode
• Claude Opus 4.6 (Thinking) – Top reasoning model, FREE in Antigravity!
• GPT-OSS 120B (Medium) – Open-source OpenAI variant

This is still huge: Claude Opus 4.6 normally requires a $100-200/month Claude Max subscription. Getting it free in Antigravity is arguably the best deal in AI coding tools right now — when the rate limits cooperate.

Time to first useful output: About 10-15 minutes including installation. The learning curve is moderate if you’re coming from VS Code, steeper if you’re used to Cursor’s polished GUI. See our Claude Code Plugins guide for how to extend your agentic workflow further.

🎯 Agent Skills: The Game-Changer (Deep Dive)

Agent Skills are the most significant update to Antigravity since launch. They solve a fundamental problem: how do you make a generalist AI model understand your specific project context without stuffing everything into the context window?

How Skills Work

A Skill is simply a directory containing a SKILL.md file. This file uses YAML frontmatter (defining the skill’s name and description) followed by natural language instructions, code snippets, or step-by-step guides.

Here’s the key insight: Skills use Progressive Disclosure. The agent only loads a skill’s full instructions when your request matches the skill’s description. This keeps the context window lean and focused.

Example: You create a “Database Migration” skill. When you ask the agent to “run a migration,” it automatically loads that skill’s specific protocols, including your team’s safety checks, naming conventions, and rollback procedures.

New in v1.20.3: Skills now work with both GEMINI.md and AGENTS.md rule files, meaning you can share the same rule sets across Antigravity and other agentic tools in your workflow.

Practical Skill Examples

1. Conventional Commits Skill: Analyzes your staged changes and generates commit messages following your team’s format. No more manually writing “feat: add user authentication.”

2. Code Review Skill: Loads your specific code review guidelines, license header requirements, and style preferences when reviewing changes.

3. Test-Driven Development (TDD) Skill: Ensures the agent writes tests before implementation and follows your testing framework conventions.

4. Landing Page Generator: Pre-built workflow for generating consistent landing pages with your brand’s components and design system.

The community has already created a 58-Skill aggregator repository with pre-built skills for Security Audit, Senior Engineering practices, Creative workflows, and more.

🖥️ The Three Surfaces: How Antigravity Actually Works

Antigravity isn’t just an IDE with an AI sidebar. It’s built around three distinct “surfaces” optimized for different parts of development:

1. Agent Manager (Mission Control)

This is where Antigravity shines. Instead of having your AI chat squeezed into a sidebar, the Agent Manager sits outside the editor. You can:

• Run up to 5 agents in parallel across different workspaces
• See which agents are thinking, waiting for approval, or have failed
• Review artifacts (plans, screenshots, recordings) that show what agents did
• Leave feedback directly on artifacts, like commenting on a Google Doc
• Download artifacts (new in February 2026) to save and share task summaries

The parallel execution is game-changing. You can assign one agent to refactor a backend API while another debugs a frontend CSS issue and a third generates unit tests. It’s like having a team of junior developers you can dispatch simultaneously.

2. Editor View (Familiar Territory)

Press Command+E (Ctrl+E on Windows) to focus the Editor for a specific project. This is the VS Code experience you know: syntax highlighting, extensions, debugging. The AI features here include:

• Tab completions: Supercomplete predicts entire function implementations
• Inline commands: Press Cmd+I to give instructions without leaving your code
• Plan mode: Generates a detailed plan before acting (ideal for complex tasks)
• Fast mode: Executes instructions instantly (ideal for quick fixes)

3. Browser (The Secret Weapon)

Antigravity includes a Chrome extension that lets agents test and validate your web applications automatically. This transforms the development loop:

Old workflow: Build feature → Manually test in browser → Return to IDE to fix issues → Repeat

Antigravity workflow: Build feature → Agent launches browser, tests UI, captures screenshots → Presents walkthrough showing how the final product works → All without human intervention until review time

For web developers building complex applications, this browser-in-the-loop approach can save hours of manual testing per week. It’s also where the new AI Studio integration pays off — design your prompt strategy in AI Studio, then let Antigravity’s browser agent validate the results in a real UI.

⭐ Features That Actually Matter (And 3 That Don’t)

Features Worth Your Attention

1. Agent Skills System ⭐⭐⭐⭐⭐

The ability to create reusable, context-aware “playbooks” for your AI agents. This transforms Antigravity from a generic tool into one that understands your specific project requirements. The new AGENTS.md support means your skills can work across multiple agentic tools.

2. Multi-Model Support ⭐⭐⭐⭐⭐

Antigravity offers eight models including Gemini 3.1 Pro (High and Low variants), Gemini 3 Flash, Claude Sonnet 4.6, Claude Sonnet 4.6 (Thinking), Claude Opus 4.6 (Thinking), and GPT-OSS 120B. The standout here is free access to Claude Opus 4.6, which normally costs $100-200/month through Claude Code. Use our Claude Code Router guide if you want to mix models strategically.

3. Secure Mode + macOS Sandbox ⭐⭐⭐⭐⭐

Three-tier terminal permission controls plus macOS workspace sandbox. After the drive-deletion incident of late 2025, these security additions are essential. The macOS sandbox (added February 23, 2026) is particularly important — it physically restricts agents to the workspace directory.

4. Google AI Studio Integration ⭐⭐⭐⭐

Now live since February 2026. Design and iterate on your agent prompts in AI Studio’s visual interface, then deploy them directly into Antigravity workflows. This bridges the gap between prompt engineering and production execution.

5. Parallel Agent Execution ⭐⭐⭐⭐

Run up to 5 agents simultaneously. This multiplies throughput dramatically. The workflow changes from serial (Code → Test → Debug) to parallel management (Assign → Monitor → Review).

Features That Sound Better Than They Are

1. “Unlimited Tab Completions”

Yes, tab completions are unlimited. But the agent requests that actually do meaningful work are rate-limited. Don’t confuse autocomplete with agentic coding.

2. “Free Forever”

The preview is free, but Google has already signaled paid tiers are coming. Team and Enterprise plans are listed as “coming soon.” Treat this as “free for now.”

3. “5-Hour Rate Limit Refresh” (for Pro subscribers)

This is the most misleading claim in March 2026. Pro subscribers ($20/mo) are reporting 7-day and even 10-day lockouts, not 5-hour refreshes. The advertised behavior applies only when demand is low — and for Claude models, demand is never low.

🧪 Real Test Results: Building a Full-Stack App

I’ve been testing Antigravity since launch. Here’s what I found in my latest round of testing (March 2026, using v1.20.3):

Test 1: Greenfield React App (Authentication + Dashboard)

Task: “Build a React app with user authentication, a dashboard showing user stats, and a settings page.”

Result: Using Claude Opus 4.6 (Thinking), Antigravity created a functional app in about 14 minutes, with 8 additional minutes for review and minor fixes. It scaffolded the component structure, set up React Router, implemented a mock authentication flow, and even added responsive styling.

Issues: The initial implementation had some optimistic imports (helper utilities that didn’t exist in my repo). Fixable, but required attention.

Test 2: Legacy Codebase Refactoring

Task: Refactor a messy 3-year-old Node.js backend with inconsistent patterns.

Result: Mixed. Antigravity understood the high-level structure but struggled with hidden edge cases. It created clean refactored code, but broke some functionality that relied on undocumented side effects.

Verdict: Better for greenfield projects than legacy code surgery. Compare with how Claude Code handles legacy refactoring if that’s your primary use case.

Test 3: Using Agent Skills for Consistent Output

Task: Generate 5 API endpoints following our team’s conventions.

Result with Skills: Created a “REST API Standards” skill with our naming conventions, error handling patterns, and documentation requirements. The agent followed them consistently across all 5 endpoints.

Result without Skills: Inconsistent naming, different error handling approaches, missing documentation on 2/5 endpoints.

Verdict: Agent Skills make a real difference for team consistency.

Task Type	Antigravity Time	Manual Time (Est.)	Quality
New React App	22 min (build + review)	2-3 hours	✅ Production-ready with minor edits
Legacy Refactoring	45 min + debugging	4-6 hours	⚠️ Functional but broke edge cases
API Endpoints (with Skills)	15 min	1-2 hours	✅ Consistent, well-documented
API Endpoints (no Skills)	18 min	1-2 hours	⚠️ Inconsistent patterns

💬 What Developers Are Actually Saying (The Rate Limit Crisis)

Community sentiment around Antigravity has been a rollercoaster. After the January performance complaints, February brought a new crisis: the rate limit system is failing paying subscribers in ways Google hasn’t publicly addressed.

The Rate Limit Crisis (February-March 2026)

The most active thread on the Google AI Developers Forum is now “Sudden jump from 5-hour reset to 4-day wait?” with 87 replies and over 10,000 views. The pattern:

• Pro subscribers hitting 7-day lockouts after minimal usage of Claude models, even with active paid subscriptions
• 10-day lockouts reported by users who started a new subscription and hit limits within hours
• One Pro subscriber reported: “New chats show a 4-day lockout, while existing sessions show a 7-day lockout. I’m paying $20/month and getting 5-7 Claude prompts per week before lockout.”
• Google engineers are reportedly not allowed to use Antigravity internally — a fact that circulated through r/singularity and r/google_antigravity

The “Paperweight” Controversy

The viral Reddit thread “I’m done. Antigravity just became a $20 paperweight” has found new life with the rate limit crisis. Earlier complaints focused on performance quality; now they focus on availability. The core complaints:

• Context Window Issues (partially fixed): The v1.20.3 token accounting fix helped, but users still report effective context closer to 64K tokens in practice
• The “Lobotomy” Effect: The widespread theory that Google uses a smaller backend model than advertised — still unconfirmed, still unaddressed
• Hallucination Spikes: Developers report the AI still frequently invents non-existent library imports, particularly on Gemini models

“When coding with Opus on Antigravity, the moment when you are forced to switch to Gemini is like handing the steering wheel to a reckless driver.” — Reddit user, Google AI Developers Forum

The Positive Side

Not all feedback is negative. Many developers still find tremendous value when the limits aren’t biting:

“Indeed, for me, Antigravity IDE has replaced VS Code.” — r/ClaudeAI user

“It felt less like a novelty and more like a shift in how you run development.” — Scalable Path review

Another heavy tester declared Antigravity “the best AI IDE at the start of 2026,” crediting its planning and understanding of codebases, particularly when using Claude Opus 4.6.

⚠️ Limitations and Known Issues (March 2026)

Let’s be completely honest about what doesn’t work well:

Technical Limitations

• Rate limit crisis for Pro subscribers: Despite paying $20/month, many users experience 7-day lockouts on Claude models. The advertised 5-hour refresh appears unreliable under real-world usage patterns. Google hasn’t fixed or acknowledged this.
• Model provider overload: During high traffic, you’ll see “Agent terminated due to error: model provider overload” messages
• Performance inconsistency: Quality varies week-to-week, with Gemini models affected most by the alleged backend infrastructure changes
• Context window discrepancy: Claimed 1M tokens, but effective context is still reported closer to 32-64K in practice (the v1.20.3 token accounting fix helps, but hasn’t fully resolved this)
• Execution loops: Agents can get “stuck” with ambiguous requirements or edge cases
• High resource usage: Users report lag, freezes, and high CPU usage, especially with multiple agents running

Platform Limitations

• No custom model integration: You can’t plug in your own API keys for alternative models
• VS Code extension compatibility: Some extensions have issues or don’t work
• Subscription syncing bugs: Multiple reports of subscription status not syncing correctly — a contributing factor to the lockout issues
• Removed Command support (v1.20.3): Some workflows that relied on the Command feature need updating

Security Considerations

Google’s own documentation states: “Antigravity is known to have certain security limitations.” Security researcher Mindgard flagged vulnerabilities in late November 2025, with five additional vulnerabilities documented by researcher Johann Rehberger. By default, agents have autonomous access to your terminal, filesystem, and network connections.

Critical Incident: One widely-cited case involved Antigravity accidentally wiping a user’s entire D drive. The new macOS sandbox (February 23, 2026) addresses this for macOS users, but Windows and Linux users should still exercise caution.

Recommendation: Use Secure Mode with at least Auto permission level. Configure Allow Lists and Deny Lists for terminal commands. macOS users: enable the workspace sandbox. Never run Antigravity with admin privileges on production machines.

🎯 Who Should Use This (And Who Shouldn’t)

✅ Antigravity is Perfect For:

1. Serious Hobbyists and Indie Hackers

The free tier provides shocking value. Build entire MVPs at zero cost. One developer reported building a complete lead generation website in a single afternoon. Hit the weekly limit? Take a break and come back fresh.

2. Developers Who Want to Experiment with Agent-First Development

If you’re curious about the “future of coding” where you delegate rather than type, Antigravity is the best risk-free way to explore it. Compare with Claude Agent Teams if you want a more controlled multi-agent experience.

3. Rapid Prototypers and “Vibe Coders”

When you want to go from idea to working demo fast, without worrying about perfect code quality. The Playground feature lets you experiment without thinking about folder structures.

4. Teams Looking to Standardize Workflows (via Agent Skills)

The Agent Skills feature with AGENTS.md support makes Antigravity excellent for teams that want to codify best practices into reusable AI workflows that work across multiple tools.

⚠️ Consider Alternatives If:

1. You Need Predictable Daily Availability

The rate limit situation in March 2026 makes Antigravity unreliable as a daily driver for intensive coding. If you can’t afford interruptions, Cursor’s unlimited usage is safer.

2. You Work Primarily on Legacy Codebases

Antigravity excels at greenfield projects but struggles with complex existing code that has hidden dependencies and undocumented side effects.

3. Consistent Quality Matters More Than Free Access

Given the ongoing performance and rate limit concerns, if you need reliable, consistent behavior, Claude Code or Cursor may be better choices.

❌ Skip Antigravity Entirely If:

1. You’re a Beginner Learning to Code

The agent-first approach means you’ll see working code without understanding how it works. That’s terrible for learning. Start with tools that explain, not delegate.

2. You Need Production Stability

This is a public preview. Crashes happen. Features change. v1.20.3 shipped with a fatal bug. Don’t bet mission-critical systems on experimental software.

3. Security is Non-Negotiable

Despite the new macOS sandbox and Secure Mode, documented vulnerabilities and the drive-deletion incident should give pause to anyone working with sensitive data. For regulated industries, wait until Google demonstrates a stronger security track record.

🔮 The Road Ahead: What’s Next for Antigravity

Immediate Priorities (What Google Needs to Fix)

• Rate limit crisis: Pro subscribers are owed an explanation and a fix. The 7-day lockout issue is the top complaint on the developer forum with 10,000+ views.
• Gemini model quality: The “lobotomy” allegations need a formal Google response.
• Transparency: Published rate limits for each tier, not vague “generous” descriptions.

Short-Term (Q1-Q2 2026)

• Team and Enterprise plan launches (pricing TBA)
• Google AI Studio integration expanding (currently live in basic form)
• Windows and Linux sandbox equivalent to the macOS sandbox
• Enhanced Google Workspace support

Medium-Term (Q3-Q4 2026)

• Gemini 3.5 integration with 2 million token context (teased)
• Native mobile preview with Android emulators
• Custom model integration (bring your own API keys)
• Video understanding for UI/UX feedback

The Big Question

Will Google commit to Antigravity long-term, or will it join Google Reader in the graveyard? The investment level (built alongside Gemini 3, acquired Windsurf talent) suggests serious intent. But the current rate limit crisis and lack of official communication are exactly the kind of trust failures that have killed Google products before. The next 60 days will tell us a lot about whether this is a platform Google is serious about.

❓ FAQs: Your Questions Answered

Q: Is Google Antigravity free?

A: Yes, Antigravity is completely free during the public preview for individuals with personal Gmail accounts. You get access to Gemini 3.1 Pro, Gemini 3 Flash, Claude Sonnet 4.6, Claude Opus 4.6, and GPT-OSS models with weekly-based rate limits. Heavy users report hitting free tier limits within 2-3 hours of intensive coding. Google AI Pro ($19.99/month) advertises 5-hour refresh cycles, but in March 2026 many Pro subscribers are experiencing 7-day lockouts instead.

Q: Is Antigravity better than Cursor?

A: It depends on your priorities. Antigravity offers free access to Claude Opus 4.6, Agent Skills customization, and browser testing automation. Cursor offers unlimited usage, more parallel agents (8 vs 5), a more polished GUI, and more consistent performance. Given the March 2026 rate limit crisis, Cursor is the safer choice for anyone who codes daily. Choose Antigravity for free experimentation with agent-first development. Read our full Claude Code vs Cursor comparison for a broader view.

Q: What are Agent Skills?

A: Agent Skills are reusable “playbooks” that teach your AI agent how to perform specific tasks according to your team’s standards. They’re directory-based packages containing a SKILL.md file with instructions. The agent loads relevant skills only when needed. As of v1.20.3, skills now work with AGENTS.md files, enabling cross-tool compatibility with other agentic coding tools.

Q: What is Secure Mode and the macOS sandbox?

A: Secure Mode offers three terminal permission levels: Turbo (minimal oversight), Auto (balanced, recommended), and Off/Manual (requires confirmation for every command). The macOS sandbox (added February 23, 2026) is a separate feature that physically restricts agent terminal commands to the workspace directory — preventing the kind of accidental full-drive deletion that was reported in late 2025. Windows and Linux equivalents are not yet available.

Q: What happened to the rate limits for Pro subscribers?

A: This is the top issue in March 2026. Google AI Pro ($20/month) advertises rate limits that refresh every 5 hours. In practice, many subscribers are experiencing 7-day and even 10-day lockouts on Claude models, with minimal usage triggering the caps. Google has not officially acknowledged or resolved this. If you need reliable daily access to Claude Opus 4.6, consider upgrading to AI Ultra ($250/month) or using Cursor as a backup.

Q: What models are available in Antigravity?

A: As of March 2026, Antigravity offers: Gemini 3.1 Pro (High and Low variants), Gemini 3 Flash, Claude Sonnet 4.6, Claude Sonnet 4.6 (Thinking), Claude Opus 4.6 (Thinking), and GPT-OSS 120B. The standout is free access to Claude Opus 4.6, the top reasoning model that normally costs $100-200/month. Model names were upgraded from the 4.5 generation in early 2026.

Q: What did version 1.20.3 fix?

A: v1.20.3 (March 5, 2026) fixed a token accounting bug that was causing conversations to prematurely hit the maximum token limit — partially addressing the context window complaints from January-February. It also added AGENTS.md support, made Auto-continue the default, and improved conversation load times. However, the release itself shipped with a reported fatal bug that required an emergency patch. Always check for the latest version before starting important work.

Q: Is my code safe with Antigravity?

A: Google notes “known security limitations.” Security researchers have documented multiple vulnerabilities, and a critical incident involved the agent accidentally wiping a user’s entire drive. Use Secure Mode (Auto or Manual), enable macOS sandbox if on Mac, configure terminal Allow/Deny Lists, and never run with admin privileges on machines with sensitive data.

Q: Will Google kill Antigravity like Reader?

A: This is a legitimate concern given Google’s history. The investment level — built alongside Gemini 3 as a flagship product, acquired Windsurf talent — suggests serious intent. However, the current rate limit crisis and lack of official communication mirror the kind of neglect that has preceded other Google product shutdowns. The upcoming Team and Enterprise plan launches will be the real test of commitment. Don’t build your entire workflow around it until Google demonstrates 12-18 months of continued, reliable development.

🏆 Final Verdict: Should You Try Antigravity in March 2026?

Yes — but with even clearer eyes than before.

Google Antigravity remains the best free deal in AI coding. Free access to Claude Opus 4.6 alone makes it worth trying. The new Agent Skills feature adds genuine customization value, the macOS sandbox addresses the security concerns for Mac users, and the token accounting fix in v1.20.3 partially resolves the context window complaints.

But the rate limit trust issue is now the dominant story. Pro subscribers paying $20/month for “5-hour refresh” cycles are being locked out for 7 days with no official acknowledgment from Google. Until this is fixed and communicated, Antigravity can’t be your only development tool.

My updated March 2026 recommendation:

• Download it today and spend a few hours experimenting on a greenfield project
• Use Claude Opus 4.6 (Thinking) when Gemini performance feels degraded
• Enable macOS sandbox (macOS) and Secure Mode (all platforms)
• Invest time in Agent Skills if you have repeatable workflows — now with AGENTS.md compatibility
• Don’t upgrade to AI Pro yet until Google fixes the 7-day lockout issue
• Keep Cursor or Claude Code as your reliable fallback for time-sensitive work
