Run Claude Code in Agentastic
Anthropic's coding agent, launched in an isolated worktree with its native settings, skills, hooks, and MCP servers intact.
What Agentastic adds
Give every task its own worktree, branch, or container.
Keep Claude Code's real CLI and your existing configuration.
Inspect the diff, run code review, test, and open a pull request.
Launch Claude Code
- Install the official CLI and sign in with your existing provider account.
- Open a repository in Agentastic. The connection is discovered from your PATH.
- Open Agent Home, choose Claude Code, describe the task, and select worktree, local, container, cloud, or remote mode.
Every run gets its own git worktree, so three tasks can share a repository without sharing a branch or a build directory.
What Claude Code supports
- Launch from a task description: supported
Type the task in Agent Home and Agentastic hands it to claude at launch, so the run starts from your prompt instead of an empty session.
- Unattended runs: supported
Claude Code can run without stopping for per-tool confirmation, which is what makes an overnight or scheduled run finish on its own.
- Plan before editing: supported
Start Claude Code in a read-only pass that proposes an approach without touching the working tree, then approve it and let the same session execute.
- Resume a session: supported
Reopen the last Claude Code session for a worktree and keep its history — useful when reviewing the diff turns up one more change.
- Structured chat: supported
Talk to Claude Code in a native chat that renders thinking, nested tool calls, plans, and permission requests as structured events instead of scraped terminal output.
- Code review: not supported
Claude Code writes the change; pair it with a review-capable agent for the pass before merge.
Agentastic reads these from Claude Code's own CLI rather than emulating them, and modes it does not support stay out of the picker. The provider reference lists the exact flags for each launch, and how to compare coding agents covers what changes when you switch harnesses.
Claude Code questions
Is there a GUI for Claude Code?
Yes. Anthropic's Claude Code Desktop is the Code tab in the Claude app. Agentastic is a native Mac alternative that runs the real Claude Code CLI (claude) with a git worktree, terminal, diff view, and code review for each task, plus a structured chat view of the session.

How do I run multiple Claude Code sessions in parallel?
Start each task from Agent Home in worktree mode. Agentastic gives every run its own git worktree and terminal, so several Claude Code sessions can work in one repository without editing the same files.
How do I install Claude Code?
Run curl -fsSL https://claude.ai/install.sh | bash, then sign in the way Claude Code's documentation describes. Agentastic finds the claude command on your PATH when you open a repository.
Does Agentastic charge for Claude Code?
No. Agentastic is free and does not proxy model calls. It launches Claude Code with the credentials and plan you already use, so any usage is billed by your provider, not by Agentastic.
