open-swe is an open-source asynchronous coding agent from LangChain, written in Python. It ships agent-app scaffolding including AGENTS.md and CLAUDE.md files and references Anthropic and OpenAI models.

Use it to
- Run coding tasks asynchronously through an open agent
- Study or extend an agent-app built with LangChain
- Use the shipped AGENTS.md and CLAUDE.md conventions in your own repos
- Swap between Anthropic and OpenAI model backends
