Run 100s of Claude agents in parallel
Mngr is a CLI tool for programmatically spinning up coding agents at any scale. It lets you compose workflows—fix all my tests, open PRs for every issue, validate every use case—and run them repeatedly. Run 1. Run 100s. See all your agents, and if they're blocked on you. Connect to any agent mid-task to ask a question or debug it. Agents start in under 2 seconds and shut down when idle. The same commands work with any agent harness, running locally, on Modal, or in Docker. Free and open-source.
