What is OpenAgent?

OpenAgent is a terminal-native AI coding agent. It reads your files, writes code, runs commands, searches the web, and ships features — all from the command line. Unlike Claude Code, it isn’t locked to a single provider: switch between Claude, GPT-5, Gemini, Grok, Llama, Ollama, MLX, LM Studio, and more with one keystroke.

Why people use it:

  • Bring your own model. Already paying for Claude Max? OpenAgent uses your existing subscription. Want GPT-5 today, Gemini tomorrow? /model and switch.
  • Run locally for free. First-class support for Ollama, LM Studio, and Apple’s MLX framework — no API costs, no rate limits, no telemetry.
  • Real agent loop. Plans, executes, verifies. Not a chat box that occasionally writes code.
  • Open source, Apache 2.0. Fork it, audit it, self-host it.
