Aizen
Git worktree workspace with integrated AI coding agents
Free Coding Open Source
Overview
Aizen is a native macOS workspace for developers who work on multiple branches in parallel. Each git worktree gets its own terminal, file browser, web browser, and AI agent session - so you switch worktrees, not windows. With built-in support for Claude, Codex, Gemini, and Kimi agents via the Agent Client Protocol, plus an integrated terminal powered by libghostty, Aizen brings order to multi-branch development workflows.
