Your terminal, with the context you need.
Rune is a minimal native macOS workspace for terminal-first development. Keep your shell at the center, with files, diffs, and Git history close at hand.
- Stay in your flow. A Ghostty-powered terminal alongside your project files.
- See what changed. Browse diffs and Git history without leaving your workspace.
- Understand the change. Get explanations, diagrams, and links to the code with Change Brief.
- Keep your hands on the keyboard. Find files, run commands, and switch branches or projects through searchable palettes.
- Pick up where you left off. Rune remembers your last project, window layout, and expanded folders.
Built for macOS 26 and newer. Small, focused, and native.
Get a clear explanation of your changes, with diagrams and links to the code. Open Change Brief from the Git sidebar or ⌘⇧P, then choose your working tree, staged changes, or PR.
Uses your installed Codex or Claude Code. Sign in first and choose your preferred agent in Settings → Change Brief. Briefs are saved so you can pick up where you left off; refresh when your changes evolve.
