Sandcastle
A TypeScript library for orchestrating coding agents in isolated sandboxes.
Sandcastle is a TypeScript library (published as @ai-hero/sandcastle) for orchestrating AI coding agents in isolated sandboxes with a single sandcastle.run() call. It sandboxes the agent with a configurable branch strategy and merges the resulting commits back. It is provider-agnostic, shipping Docker, Podman and Vercel (Firecracker microVM) providers plus APIs for custom ones, and is aimed at parallel AFK agents and review pipelines; the quick start runs Claude Code via an OAuth token or API key.
