Compare Antigravity and Claude Code, then keep both
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.
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.
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.
