SWE-agent
SWE-agent is a research framework that enables large language models (LLMs) like GPT-4o or Claude Sonnet to autonomously interact with codebases, fix GitHub issues, and perform complex software engineering tasks. It provides a configurable, tool-using agent environment built by researchers at Princeton and Stanford. The tool is designed for maximum agent autonomy and is highly hackable. It's configured via a single YAML file and supports adding custom tools. While it's state-of-the-art on the SWE-bench benchmark, the project is now in maintenance mode, with development focused on its successor, mini-swe-agent.

What it actually does
Who uses it
Real use cases, no hype- State-of-the-art performance on SWE-bench for open-source projects.
- Free-flowing and generalizable design, giving the language model maximum agency.
- Highly configurable and fully documented with a single YAML config file.
- Built for research—simple and hackable codebase.
- Active research community from top institutions (Princeton, Stanford).
- Supports multimodal inputs for vision-capable models.
- Tool bundle architecture for custom, environment-specific tool definitions.
- Officially superseded; now in maintenance-only mode.
- More complex than its recommended successor, mini-swe-agent.
- Documentation can be sparse or error-prone (e.g., 404 FAQ page).
- Requires specific model API keys and environment setup.
- Core value is in solving SWE-bench; may be overkill for simpler tasks.
- Heavy dependency on specific LLM providers for top performance.
- Action parser and history processor systems add configuration complexity.
