Build with Agentastic

A native macOS IDE for running many AI coding agents at once — each in its own git worktree, with a real editor, a GPU-accelerated terminal, a browser, and diff review in the same window. Free, and it drives the agent CLIs you already have installed.

What you can only do here

The capabilities that are genuinely ours. Each one is a page.

Run 20 agents at once

Every agent gets its own git worktree, so parallel work never collides.

Chat with 30 agents

Claude Code, Codex, Cursor, Droid, Goose and more — one readable transcript.

Agents that run other agents

A standing manager with objectives, a wiki, and workers it starts itself.

Connect a tool once

MCP plugins reach every agent. Credentials live in the Keychain, never the repo.

Ship while you sleep

Schedule a whole launch — repo, agent, prompt, plugins — with its own memory.

Know what agents cost

Quotas, tokens, and spend by model and worktree, computed on your Mac.

Your agents in your pocket

Answer a permission prompt from your iPhone, end-to-end encrypted.

Every worktree on one board

Diff counts, PR state, and live terminals on each card.
