zest

Zest is a Mac utility that brings your development tools into a radial menu. Hold option-space, flick toward a slice, and trigger Claude Code, Codex, Gemini CLI, or any shell command without leaving your project. Each slice runs locally on your Mac with your own API keys, so your code never touches Zest's servers.

You can create custom slices by dropping a .zest.yml file in your repo. Name each slice, pick an agent, write a prompt using variables like {selection}, {screenshot} or {ask}, and commit it so your whole team gets the same wheel. Slices can run in isolated git worktrees on separate branches, letting you review diffs before merging changes back.

Zest works with Xcode projects, Node apps, Python codebases and anything else. The app runs on macOS 26 or later and includes optional Ghostty terminal integration. You pay once for a lifetime license with all 1.x updates included, and can use it on up to 3 Macs.
