# Agentastic: Parallel AI Coding on macOS

> Run multiple AI coding agents simultaneously in isolated git worktrees. No conflicts, no blocked workflows — just parallel progress.

Agentastic is a native macOS code editor built for AI-first development. Instead of running one AI agent at a time and waiting, you launch multiple agents in parallel — each working in its own isolated git worktree or Docker container — so you can review finished work while more keeps coming in.

## How Agentastic works

Each AI agent you launch gets its own git worktree — a complete, independent checkout of your repository on a separate branch. Agents edit files, run commands, and make changes in complete isolation. When an agent finishes, you review its diff, run AI code review, and merge or discard — all without interrupting your own work.

<Steps>
  <Step title="Install Agentastic">
    Install via Homebrew: `brew install agentasticai/tap/dev`, or download the `.dmg` from [agentastic.dev/download](https://agentastic.dev/download).
  </Step>

  <Step title="Open your project">
    Press `Cmd+O` to open any git repository. Agentastic works with any project that has git initialized.
  </Step>

  <Step title="Launch an agent">
    Open Agent Home, write a prompt describing your task, select an AI agent, and click **Send**. Agentastic creates a worktree and starts the agent automatically.
  </Step>

  <Step title="Review and merge">
    When the agent finishes, open the Diff Viewer to review changes. Run AI code review for a second opinion, then merge or discard.
  </Step>
</Steps>

<Note>
  Agentastic requires macOS 14.0 (Sonoma) or later. Both Apple Silicon and Intel Macs are supported.
