Choose by the model family you want and by ecosystem: Claude Code for Anthropic models with MCP and Skills support, Codex CLI for OpenAI models and its cloud sandbox, Gemini CLI for Google models with a generous free tier. Feature sets converge quickly; verify against current docs before relying on a difference.\n\n## Comparison (as of 2026-09)\n\n| | Claude Code | Codex CLI | Gemini CLI |\n| --- | --- | --- | --- |\n| Vendor | Anthropic | OpenAI | Google |\n| Open source | No (npm package) | Yes | Yes |\n| MCP client | Yes | Yes | Yes |\n| Skills / instruction files | `SKILL.md`, `CLAUDE.md` | `AGENTS.md` | `GEMINI.md` |\n| Hooks and automation | Yes | Limited | Limited |\n| Cloud or sandboxed runs | Yes | Yes | Via Google Cloud |\n| Free tier | No (subscription or API) | With ChatGPT plans | Yes, rate-limited |\n\n## Deciding questions\n\n- Which model do you already pay for?
