Free alternatives to Claude Code
8 free programs that can replace Claude Code, each pairing checked by Radar's AI reviewer or by Radar.
Claude Code is Anthropic's AI coding assistant, which works in your terminal and project folder. Developers use it to read a codebase, write and change code, run commands and tests, and handle repetitive tasks. It is used through a paid plan or by paying for model usage.
Before you switch, check these points:
- Which AI model the alternative uses and who provides it. Many tools need an account or key from a model provider, and that usage can still cost money.
- Your project instructions, such as CLAUDE.md files, custom commands, hooks and MCP connections, and whether the alternative reads similar files.
- How it asks for permission before editing files or running commands.
- Editor integration, and the terminal or desktop interface you prefer.
Keep your work in version control so you can review and undo anything an agent changes. The list below includes opencode, Codex CLI and others.
