# Antigravity vs Claude Code

Google Antigravity is Google's agent-first development platform, with an app, CLI, IDE extensions and SDK, a $0 individual plan with weekly rate limits, and Gemini models. Claude Code is Anthropic's coding agent, included in paid Claude plans and built around Claude models. Both have five-hour and weekly limits on paid plans, and Reason's web and Mac apps can carry a task on when either runs out.

[Start with Reason](https://reasonmachines.com/) on the web, or [download Reason for macOS](https://reasonmachines.com/download).

## Compare Antigravity and Claude Code, then keep both

1. **Try the same task in both**: Give Antigravity and Claude Code a task you already know the answer to, and compare the result with the limits each plan leaves you.
2. **Open Reason on the web or the Mac app**: Sign in at reasonmachines.com, or download the Reason Mac app for macOS from reasonmachines.com/download and sign in there. Both open the same Sessions.
3. **Carry on in Reason when one runs out**: Push the branch, then tell Reason in the composer what is done and what is next, and pick a model on an account that still has usage.

## Honest tradeoffs

Antigravity's free plan makes it the cheaper place to start, and its paid tiers come with Google AI subscriptions you may already have. Claude Code suits people who want Claude models in their terminal and already pay for a Claude plan. Google doesn't publish exact request counts for Antigravity's quotas, and Anthropic describes Claude's in multiples of Pro, so compare them on your own work.

## Questions

### Is Antigravity free?

Google lists a $0 individual plan with basic weekly rate limits. Google AI Pro and Ultra raise the limits.

### Did Antigravity replace Gemini CLI?

For individuals, yes: free and Google AI Pro and Ultra access to Gemini CLI moved to Antigravity CLI on June 18, 2026. Gemini CLI remains for Code Assist licenses and paid API keys.

### What if both run out?

Carry the task on in Reason's web or Mac app: push the branch, tell Reason what's next, and run it on another model account you connect or on a Reason plan's credits.
