Phasr
Open-source desktop workspace for running parallel AI coding agents with Git worktree isolation.
Phasr is a free, open-source AI code editor that lets you run multiple coding agents in parallel. Each agent works in its own isolated Git worktree, preventing file collisions. Real-time diffs, per-agent status tracking, and human-in-the-loop review workflows ensure you stay in control before merging. Supports Claude Code, Codex CLI, Gemini CLI, Cursor, Aider, and any CLI-based agent. One-click deep links to VS Code, JetBrains, Xcode, and more.

How to use Phasr?
Download the macOS app from GitHub releases or build from source. Launch Phasr, connect your Git repository, and create tasks. Assign each task to a compatible agent (Claude, Codex, etc.) by configuring the CLI command. Agents run automatically in isolated Git worktrees. Review changes in the built-in diff viewer, approve or reject per file, then merge approved changes to your main branch. You can also open any worktree in your preferred IDE with a single click.
