Reasonix

Reasonix is an open-source, DeepSeek-native coding agent for the terminal. Its Go CLI/TUI supports tools, plugins, OpenAI-compatible endpoints, and cache-stable sessions.

Reasonix Desktop brings the open-source Reasonix coding agent to a native interface for macOS, Windows, and Linux, using the same local engine as its CLI/TUI.

Reasonix connects its open-source coding agent to VS Code and VSCodium through ACP, sharing editor context with the same local engine used by its CLI and desktop app.
