GitHub - langchain-ai/open-swe: An Open-Source Asynchronous Coding Agent
Highlights
- ▸open-swe is LangChain's open answer to Claude Code / Cursor Composer — same pattern, self-hostable, forkable, LangGraph-native
- ▸Async-by-default changes the UX: tasks run in the background and report when done, instead of the 'agent types, you wait' model of synchronous tools
- ▸For teams that don't want to lock in to a SaaS coding agent, open-swe is the reference scaffolding to build their own — orchestrator loop + tool use + planning as composable pieces
