Gemini CLI vs Claude Code: Should you still use Gemini CLI, or Claude Code?
Summary
Derived from sourced facts, not from builder opinions- Gemini CLI stopped serving free users and Google AI Pro and Ultra subscribers on June 18, 2026. Google moved them to Antigravity CLI, so for most individual developers the real choice is Antigravity or Claude Code, which the Antigravity vs Claude Code comparison covers.
- Gemini CLI still works with a paid Gemini API key or a Gemini Code Assist Standard or Enterprise license, and Google still ships releases.
- Google says Gemini CLI is not optimized for its latest models, including Gemini 4 Argon, and points to Antigravity for them.
- Claude Code with Opus 5.5 leads Terminal-Bench 4.0 at 64.85%. Gemini CLI has no entry on that board.

Switching checklist
- Install Claude Code with curl -fsSL https://claude.ai/install.sh | bash on macOS or Linux, or irm https://claude.ai/install.ps1 | iex in Windows PowerShell, then run claude in your project.
- Sign in with a Pro, Max, Team or Enterprise plan, or a Console account. The free Claude plan does not include Claude Code.
- Import GEMINI.md into a CLAUDE.md with a line such as @GEMINI.md, or run /init to write a new one.
- Copy the MCP servers declared in ~/.gemini/settings.json, which is where Gemini CLI keeps them.
- Add each one to Claude Code with claude mcp add-json, passing the object inside mcpServers.
- Pick a model with /model: opus (Opus 5.5) is the default on paid plans, with sonnet, haiku and fable also available.
- Run one real task in your own repository with both tools and compare the diffs before moving a team.
