What is Google Antigravity and how to download

What Is Google Antigravity?

1. Agent-First IDE
   • It’s built around AI agents (not just code suggestions). These agents can plan, write, test, and verify code more autonomously. Google Developers Blog+2Real Python+2
   • Agents have access to:
     • Editor (like a code IDE) Google Developers Blog+1
     • Terminal Google Developers Blog
     • Browser (they can control a browser to test web apps) India Today+2Google Developers Blog+2
2. Artifact Generation for Transparency
   • Agents produce “Artifacts” — these are like verifiable records of what they do: task lists, implementation plans, screenshots, even browser recordings. Google Developers Blog
   • This helps you audit and review what the AI did (so it’s not a black box). GlobalGPT+1
3. Multiple Views / Interfaces
   • Editor View: Like a normal IDE (similar to VS Code) but with agent assistance. Google Developers Blog+1
   • Manager View: A “mission control” for managing multiple agents across different tasks / workspaces. Google Developers Blog
4. Model Support
   • Primarily built for Gemini 3 Pro (Google’s model) Wikipedia
   • Also supports other models like Claude Sonnet 4.5 and GPT-OSS. Google Developers Blog+1
5. Availability
   • It’s in public preview right now. Google Developers Blog
   • Supported platforms: Windows, macOS, Linux. Google Developers Blog
   • Google says there are “generous rate limits” for usage. The Times of India

   • After login, you can start by creating a workspace for your project. Reddit
4. Using Agents
   • You can spawn agents to do tasks: write code, test, run browser checks, etc.
   • Review the Artifacts they produce to verify what they did.
5. Feedback & Iteration
   • You can give feedback on the artifacts (e.g., comment on the plan or a screenshot), and the agents will adapt. Google Developers Blog
   • Agents can also learn from past work (knowledge base) to improve future tasks. Google Developers Blog

Pros and Considerations

Pros:

• Very powerful: agents can automate full workflows.
• Transparent: artifacts make it easier to trust what agents are doing.
• Multi-agent orchestration: good for complex or parallel tasks.

Considerations / Risks:

• It’s still in preview, so there may be bugs. Some users on Reddit reported instability or login issues. Reddit+2Reddit+2
• Rate limits: although “generous,” heavy usage might hit caps. India Today
• It requires a Google login / account setup.
