Parallel feature development

Launch multiple agents to work on different features (e.g., auth middleware, rate limiting, webhook retry logic) at the same time.

Code review and approval

Review file-level diffs and line counts before merging any agent-generated code into the main branch.

Multi-provider experimentation

Run agents from different AI providers (Claude, Codex, Gemini, Cursor) side-by-side to compare results.

Isolated task execution

Use Git worktrees to keep each agent's changes completely separate, preventing file collisions and merge conflicts.

IDE integration

Open agent-generated code in your preferred editor (VS Code, Cursor, JetBrains, Xcode, etc.) with one-click deep links.

Parallel execution

Run dozens of agents at once across independent tasks, each in its own isolated environment with live status and progress visibility.

Universal compatibility

Works with any CLI agent that runs in a terminal—no vendor lock-in or proprietary protocols required.

Git worktree isolation

Every agent automatically gets its own Git worktree, ensuring zero-conflict parallel development and clean merge paths to main.

Real-time diff review

See exactly what each agent changed with file-level diffs and line counts before approving or rejecting changes.

One-click IDE integration

Open any agent's code directly in VS Code, Cursor, Zed, JetBrains, Sublime, Terminal, Xcode, or Finder with keyboard shortcuts.

Approval workflow

Keep humans in control by reviewing and approving changes before merging them into the main branch.

Automatic resource management

The tool handles resource allocation across concurrent tasks, with real-time progress tracking and status updates.
