What is Google Antigravity?

Antigravity is Google's answer to the agent era of coding: instead of autocompleting lines, its agents plan a task, edit files across a project, run terminal commands, drive a browser and check their own work, while you supervise from a mission-control view. It ships as a desktop IDE, a command-line tool and editor extensions, and runs Google's Gemini models alongside Anthropic's Claude models on paid plans.

Unusually for Google, the free tier is real: the Individual plan costs nothing and includes a weekly agent quota with unlimited tab completions. There is no Antigravity-only subscription — bigger quotas ride on Google AI plans, from AI Pro at $19.99/mo up to Ultra tiers at $99.99 and $199.99/mo, and companies buy seats through Gemini Enterprise from $30/seat/mo.

Who Google Antigravity Is Best For

Best for: Google Antigravity is a strong fit for developers and engineering teams: Generous free tier for an agent platform; multi-model access without separate subscriptions. The free plan makes it easy to try on real work before paying anything.

Not ideal for: It may not suit you if any of these are dealbreakers: quota system is opaque — Google publishes no exact numbers; pricing rides on Google AI plans, which reprice often.
