Capy
An IDE and dashboard for orchestrating fleets of cloud coding agents.
Capy says it was built from scratch for multi-agent orchestration. Developers assign feature, bug and refactor tasks to parallel coding agents, each on its own branch and sandboxed cloud VM, and the agents plan, build and open pull requests that are reviewed as normal. It ships desktop apps for macOS, Windows and Linux plus a web app, a Slack integration, automations, and end-to-end testing with native computer use, browser use and annotated videos. Capy (YC F24) was founded in 2024 in San Francisco by Nalin Semwal and Justin Sun.
