Gemini CLI vs Antigravity CLI: What Changed in 2026
Gemini CLI vs Antigravity CLI after Google's 2026 transition: consumer access, enterprise exceptions, pricing, migration, and feature differences.
For most individual developers, this is now a migration decision rather than a choice between two equally supported Google tools. Google ended free, Google AI Pro, and Google AI Ultra request service for Gemini CLI on June 18, 2026. Antigravity CLI is the consumer successor. Gemini CLI remains available to organizations with Gemini Code Assist Standard or Enterprise licenses and through paid Gemini or Gemini Enterprise Agent Platform API keys. The open-source Gemini CLI repository still matters, but the consumer backend and subscription access that made it broadly free no longer do.

Key Differences
- Consumer access: Antigravity CLI has a $0 individual tier plus higher quotas through Google AI Pro and Ultra. Gemini CLI no longer serves free or consumer Google AI subscription requests.
- Enterprise exception: Gemini CLI remains supported for Gemini Code Assist Standard and Enterprise customers and through paid Gemini or Gemini Enterprise Agent Platform API keys.
- Architecture: Antigravity CLI is a Go client for the shared Antigravity agent platform. It can run asynchronous multi-agent work without tying up the terminal session. Gemini CLI uses the earlier open-source terminal agent architecture.
- Workflow migration: Antigravity keeps Agent Skills, Hooks, Subagents, and Extensions under the new Antigravity plugin model, but Google says feature parity was not complete at launch.
- Source availability: Gemini CLI publishes its Apache 2.0 client source. Antigravity CLI has a public repository for documentation and releases, but Google does not publish an equivalent client source license there.
Which Should You Choose?
Choose Antigravity CLI for a personal account or Google AI subscription because it is the supported consumer path. Keep Gemini CLI when an enterprise license or paid API-key workflow already supports it and the open-source client is important to your team. Before moving shared workflows, test each Gemini CLI extension against the Antigravity plugin equivalent because Google did not promise one-to-one feature parity at launch.
