oh-my-pi

Oh My Pi is an AI coding agent that lives in your terminal. It reads your code, makes edits, runs commands, and drives whole workflows. What sets it apart is that it wires in the machinery a real IDE uses: language servers for accurate renames and refactors, and actual debuggers (lldb, Delve, debugpy) so the model can step through running code instead of guessing. MIT licensed and completely free.

Setup is a one-line install through curl, Homebrew, or Bun, and the same binary runs on macOS, Linux, and Windows with no WSL. It picks up rules, skills, and MCP servers from the config folders of Claude, Cursor, Windsurf, Codex, Cline, and Copilot. It works with more than 60 model providers, local runners like Ollama and llama.cpp included, and signs in with existing subscriptions like GitHub Copilot as well as API keys.

The tool costs nothing. What you pay is the model bill, and a swarm of subagents plus browser automation runs that up faster than a single-threaded assistant. Solo devs and small teams comfortable in a terminal: this is a legitimate free alternative to a Cursor subscription.

The catch is maturity. It is a hard fork of another young project, shipping several releases a week. A company, Stencil Labs, now stands behind it, but there is no support offering. Treat it as a powerful tool you are willing to debug.
