LangChain Open-SWE: Async Coding Agent With Slack and Linear Integration — 7,819 Stars
Story
LangChain released Open-SWE, an open-source asynchronous coding agent built on LangGraph that analyzes codebases, plans implementation, writes code, runs tests, and opens PRs autonomously. The killer integration: mention @openswe in any Slack thread or comment @openswe on any Linear issue and it starts working. This is the architecture Cognition and Devin built privately, now fully open-source and forkable for self-hosted deployment with cloud sandboxes and subagent orchestration.
