Comparison

Agentastic vs Claude Code

Claude Code is Anthropic's CLI agent. Agentastic is the workspace around it — it can launch many Claude Code instances in parallel, each in its own git worktree, with a diff viewer and built-in code review for the changes Claude proposes. They're complements, not competitors.

Who should choose each option

Agentastic

Choose Agentastic when you want to run more than one Claude Code session at a time and review the diffs visually.

Claude Code

Frequently asked questions

Do I still pay Anthropic if I use Claude Code through Agentastic?

Yes. Agentastic does not resell agent capacity — you log in with your existing Claude Pro / Max / API credentials.

Can I run multiple Claude Code sessions on the same repo without conflicts?

Yes. Each session lives in its own git worktree, so two agents can edit the same repo in parallel without stomping on each other.

Can I review what Claude Code changed before committing?

Yes — Agentastic's diff viewer shows every change, and you can run Claude / Codex / CodeRabbit as a second-opinion code reviewer.
