ManyAgents

ManyAgents is a macOS app that runs a team of Claude Code and Codex agents from one window: an orchestrator splits your request into tasks, workers build each one in its own git worktree, and read-only reviewers check the result.

Why it matters

For developers already paying for Claude Code or Codex who want to run several agents on one project without juggling terminals. It organizes the work into roles and puts every question that needs you in one place.

Highlights

• Orchestrator, worker, thinker and reviewer roles: workers each get their own git worktree, thinkers handle hard design calls, and reviewers can only read.
• Reviewers run on a different provider than the worker when Codex is set up, so a model isn't checking its own work.
• A card view shows every agent across every project, and a 'Needs you' panel collects each decision with the agent's recommendation.
• Built-in browser lets agents click through your app to test flows, and an iOS Simulator panel shows iPhone builds beside the chat.
• Uses your existing Claude Code and Codex plans, so there's no extra AI bill; the makers say code isn't sent to them and the app has no analytics.

Worth knowing: Not affiliated with Anthropic or OpenAI; it drives their CLIs under your own accounts, so usage counts against your plan limits. After the trial, new work pauses until you buy a license.
