Orchestrate sandboxed coding agents in TypeScript with sandcastle.run()

A provider-agnostic TypeScript toolkit for sandboxing coding agents — Sandcastle lets you invoke AI coding agents via a single sandcastle.run() call, handling sandboxing, branch strategies, and merging commits back automatically. It supports OS-level sandboxes, Docker/Podman, and cloud providers like Daytona, E2B, Fly.io, Modal and Vercel, making it useful for parallelizing AFK agents or building review pipelines.
