Gemini CLI vs Claude Code
Comprehensive comparison of Gemini CLI and Claude Code for terminal-based AI development. Compare features, pricing, skills support, and real-world performance.
Both Gemini CLI and Claude Code are terminal-native AI coding agents, but they take fundamentally different approaches. Gemini CLI (now transitioning to Antigravity CLI) was open-source with a generous free tier, offering 60 requests per minute with Gemini 2.5 Pro and a 1M token context window. Claude Code is closed-source starting at $20/month but offers superior reasoning with extended thinking mode.
Key differences: Gemini CLI excels at breadth with its massive context window and Google Search grounding, while Claude Code excels at depth with its multi-step reasoning and code understanding. For skills, both support the SKILL.md open standard, meaning skills are largely portable between them.
Pricing: Gemini CLI offered the best free tier in the market before deprecation. Antigravity CLI continues with a free Flash tier. Claude Code requires a Max subscription ($20/month) or API credits.
Ecosystem: Claude Code has the more mature MCP server ecosystem. Gemini CLI/Antigravity has deeper Google Cloud integration and the official Google Skills Repository.
Recommendation: Choose Antigravity CLI if you work heavily with Google Cloud services or need cost-effective AI assistance. Choose Claude Code if you need the strongest reasoning capabilities and are willing to pay for premium performance.
