What it is AI-extracted, prompt v1, taxonomy v1, 2026-08-29, confidence not recorded

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
