Supacode

Supacode is a native macOS application designed to serve as a command center for terminal-based coding agents. Built on libghostty rather than Electron or web wrappers, it delivers native macOS performance for managing multiple AI coding workflows simultaneously.

The core concept revolves around git worktree isolation. Each coding agent runs in its own dedicated git worktree, preventing file conflicts and enabling true parallel development across a single repository. Users can run 50 or more agents at the same time, each operating in its own sandboxed environment.

Supacode follows a bring-your-own-agent philosophy. It works with any CLI-based coding agent including Claude Code, OpenAI Codex, and Opencode. There is no translation layer or proprietary agent runtime. Agents run directly in the built-in terminal, which supports tabs, panes, and splits for organizing multiple sessions.

The built-in terminal is powered by GhosttyKit, the same engine behind the Ghostty terminal emulator. It includes full terminal emulation with search, notifications, and keyboard shortcut support. A command palette provides quick access to common actions.

GitHub integration is built in through the GitHub CLI. Users can open pull requests, review CI check status, and resolve merge conflicts without leaving the application. Repository commands can be configured per-project to automate common workflows.

Supacode stores all configuration and state locally. It requires macOS 26 (Tahoe) or newer and needs Git installed in the shell. For GitHub features, the GitHub CLI must be authenticated. The app is distributed as a direct DMG download and through Homebrew.

The project is fully open source under a public license on GitHub. It is written in Swift using SwiftUI and The Composable Architecture pattern. Developers can build from source using the provided Makefile, which handles compiling the GhosttyKit XCFramework from Zig source code and building the macOS app.
