Multi-agent IDE for macOS
Run many coding agents without losing the codebase.
Agentastic.dev gives Claude Code, Codex, Gemini, Cursor, Copilot, Junie, OpenHands, and more their own isolated git worktrees, terminals, browsers, and diff reviews.
What makes an IDE multi-agent?
A multi-agent IDE is not just an editor with a chat panel. It is a control room for parallel software work: separate tasks, separate worktrees, separate terminals, separate browsers, and one review surface where you decide what lands.
Parallel agents
Launch several coding agents at once and keep their runs visible, resumable, and scoped to the task they own.
Worktree isolation
Each agent works in its own git worktree or container, so changes stay separated until you review and merge them.
Built-in review
Inspect diffs, compare agent output, and run code review before work reaches your main branch.
A practical workflow for agentic development
Send one issue, bug, or experiment to each agent.
Give every run a clean branch and worktree.
Watch terminals, browsers, and task status in one app.
Review diffs and keep only the changes that earn it.
Bring the agents and editors you already use
Agentastic.dev is designed for the agent stack developers already have, not a single locked-in assistant. Pair it with your subscriptions, models, editors, and command-line tools.

Multi-agent IDE FAQ
What is a multi-agent IDE?
A multi-agent IDE is a development workspace built for running more than one coding agent at the same time. Instead of sending every task to one assistant in one working tree, each agent gets its own isolated workspace, terminal, browser, and diff.
How is Agentastic different from an AI editor?
AI editors usually add chat, autocomplete, or one built-in agent to a single editor session. Agentastic is a native macOS workspace for launching many CLI agents in parallel and reviewing each result before you merge.
Can I keep using Cursor, Zed, VS Code, or Xcode?
Yes. Agentastic sits around your editor. You can open any agent worktree in Cursor, Zed, VS Code, Xcode, JetBrains IDEs, or a terminal.
Why use git worktrees for agents?
Git worktrees keep parallel agent changes separated. One agent can refactor a feature while another fixes a bug, and neither one tramples the other agent's files.
