Introducing Open SWE: An Open-Source Asynchronous Coding Agent
Open SWE is an open-source asynchronous coding agent developed by the LangChain team, enabling tasks to be delegated from GitHub issues or a custom UI. It operates as a collaborative engineer, handling research, planning, code writing, testing, review, and pull request creation, and integrates directly with GitHub for secure, isolated execution. The system uses a multi-agent architecture with a Planner and Reviewer to ensure quality checks before code submission, and is deployed on the LangGraph Platform for long-running tasks. It supports asynchronous execution, cloud-based processing, and is designed to be extensible for customization.
