A TypeScript library for orchestrating AI coding agents (like Claude Code) inside isolated sandboxes via a single sandcastle.run() call. It handles sandboxing with configurable branch strategies and merges agent commits back, with built-in providers for Docker, Podman, and Vercel.
Use cases
- run multiple AI coding agents in parallel safely
- sandbox claude code agent execution in docker
- orchestrate AFK coding agents and merge their commits
- build review pipelines for AI-generated code
- run coding agents in isolated firecracker microvms
- create custom sandbox providers for agent execution
When to choose
- you want to run AI coding agents with container isolation and automatic branch/merge workflows
- you need to parallelize many autonomous agent runs in TypeScript
- you want provider-agnostic sandboxing across Docker, Podman, or cloud microVMs
When to avoid
- you need a general-purpose agent framework beyond coding tasks
- you don't use git or can't run containers or cloud sandboxes
- you want a GUI for managing agents rather than a code-first API
