Overview

pi-gui is a native Mac desktop interface for the pi coding agent (mariozechner/pi), giving developers a Codex-style GUI around AI-assisted coding workflows instead of a pure CLI. Open multiple project workspaces in parallel with independent session histories, resume previous sessions across restarts, and watch agent activity in a real-time timeline that surfaces every tool execution, code modification, and reasoning step with full input/output details. The app is extensible through skills and slash commands for switching models, changing thinking levels, and scripting custom workflows. Built on Electron, React, TypeScript, and Vite, pi-gui cleanly separates the desktop shell from the underlying pi agent runtime so each can evolve independently. Signed and notarized DMG releases are provided, and installation is available via GitHub Releases or Homebrew (brew install --cask pi-gui). Open source under MIT, currently in beta for macOS (Apple Silicon) and Linux (AppImage).

Pricing: Free (open source, MIT)

Architecture: Apple Silicon
