Google Antigravity is an agent-first IDE that orchestrates up to five AI agents in parallel across your editor, terminal, and a built-in browser, built for developers who want to delegate whole features instead of typing line by line. Launched in late 2025 and maturing through 2026, it treats agents as first-class workers with their own workspaces and verification loops.
Core Features
- Up to 5 parallel agents plan, code, test, and verify simultaneously in separate git worktrees.
- A built-in Chromium browser agent closes the loop from code change to UI check inside one tool, no Playwright setup needed.
- Per-mission model selection across Gemini 3.1 Pro, Claude Opus 4.6, and GPT-OSS 120B.
- A 1M to 2M token context window handles large monorepos and very long files.
- A standalone desktop app for macOS, Windows, and Linux, not a VS Code fork, with MCP server support.
Use Cases
- Full-stack builds where frontend verification matters and you want browser testing built in.
- Teams already on Google Cloud, Firebase, or Vertex AI wanting native platform hooks.
- Developers who want free Opus-level models without paying 100 dollars plus per month elsewhere.
Pricing
Public Preview is free for personal Google accounts and rate-limited, and it includes Gemini 3 Pro and Claude Opus 4.6. Google AI Pro costs 20 dollars per month for higher limits; Ultra is 249.99 dollars per month. Credit packs run 25 dollars per 2,500 credits for burst usage.
Our Take
Best free on-ramp to multi-agent coding if you can tolerate preview rate limits and occasional instability. The trade-off is that it is standalone only, cloud-only, and uses opaque credit pricing, which makes it weak for enterprises with data-residency rules.
