    Luna sobre el mar,


    granos de arena brillan,

## About

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.
