**Short answer.** All three are terminal coding agents that read a repository, run commands, and edit files. 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.
