Open SWE is an open-source cloud-based asynchronous coding agent built with LangGraph. It autonomously understands codebases, plans solutions, and executes code changes across entire repositories—from initial planning to opening pull requests.
Core Features
Intelligent Planning
Open SWE has a dedicated planning step which allows it to deeply understand complex codebases and nuanced tasks. You’re also given the ability to accept, edit, or reject the proposed plan before it’s executed.
Human in the Loop
With Open SWE, you can send it messages while it’s running (both during the planning and execution steps). This allows for giving real time feedback and instructions without having to interrupt the process.
Parallel Execution
You can run as many Open SWE tasks as you want in parallel! Since it runs in a sandbox environment in the cloud, you’re not limited by the number of tasks you can run at once.
End-to-End Task Management
Open SWE will automatically create GitHub issues for tasks, and create pull requests which will close the issue when implementation is complete.
Use Cases
Open SWE is suitable for various software development scenarios:
- Automated code refactoring and optimization
- Large-scale codebase maintenance
- Bulk code changes across repositories
- Continuous integration and deployment automation
- Code review assistance tools
- Technical debt management and cleanup
