Open SWE is an open-source cloud-based coding agent built with LangGraph. It’s designed to autonomously understand, plan, and execute code changes across entire repositories.

​
How It Works

Open SWE operates through three specialized LangGraph agents:
  • Manager Graph: Orchestrates user interactions and coordinates between other graphs
  • Planner Graph: Analyzes requirements and creates detailed execution plans
  • Programmer Graph: Executes code changes based on approved plans
The agent can be used through a web interface or triggered automatically via GitHub webhooks, making it flexible for both interactive development and automated workflows. Open SWE UI Screenshot
