The agent orchestrator for Claude Code.
Luna sobre el mar,
granos de arena brillan,
noche de cristal.

Warning
Early Development — This project is under active development. Real usage is not recommended at this time. Expect breaking changes and potential data loss until we reach a stable release.
Sandcastle is an open-source agent orchestrator for managing fleets of AI coding agents. Spawn isolated development environments, assign Claude Code instances to specific tasks, and monitor progress across all your work streams—from a beautiful, unified interface.
Built with a client-server architecture, Sandcastle lets you host your orchestration server wherever you want and connect from desktop or web clients. Multi-client streaming keeps everything in sync, so you can seamlessly switch between devices while your agents keep working.
