Google Antigravity vs Claude Code: documented features compared

Short answer

Antigravity is Google’s agent-first IDE, CLI and app, free to start with higher limits on Google AI Pro and Ultra. Claude Code is Anthropic’s agentic tool for the terminal, IDEs and a desktop app, included in paid Claude plans. Both support MCP and SKILL.md skills; they differ in config files, rules format and plan packaging.

How this comparison was made: we have not run hands-on tests or benchmarks of either agent. Every row summarises the vendor’s own documentation and links to it. Prices are list prices as published on the date above and can change.

Frequently asked questions

We have not tested them hands-on, so we do not rank them. Both document MCP and SKILL.md skills. The documented differences are surfaces, rules format and how plans are priced.
