ouroboros vs SWE-agent
Persistent AI agent compared with a repository issue-fixing tool
ouroboros is a persistent, self-modifying AI agent for desktop or headless use, while SWE-agent equips language models to work on software repositories and attempt GitHub issue fixes. ouroboros emphasizes ongoing memory and autonomous evolution; SWE-agent focuses on configurable software engineering research and tasks, with its maintainers recommending mini-SWE-agent for new use.

ouroboros: Run a Persistent, Self-Modifying AI Agent
Ouroboros is a Python AI agent for desktop or headless use, designed to retain identity and memory across tasks and restarts. It can work in external projects, coordinate specialist agents, and evolve its own implementation through reviewed changes.

SWE-agent: Use Language Models to Fix GitHub Issues
SWE-agent gives a language model tools to work on real software repositories, including diagnosing and attempting to fix GitHub issues. It is designed for software engineering research and configurable coding tasks, though its maintainers now recommend mini-SWE-agent for new use.

Key differences
- ouroboros retains memory, conversation history, and identity across tasks and restarts; SWE-agent is organized around repository work such as attempting to fix a GitHub issue.
- ouroboros can coordinate specialist agents and evolve its own implementation through reviewed changes; SWE-agent provides repository tools and configurable workflows for research and coding tasks.
- ouroboros runs as a desktop app or headless CLI, with a local runtime and remote API or local GGUF inference; SWE-agent connects a chosen language model to repository tools.
- Both projects use Python and have an MIT license.
- ouroboros targets persistent assistance, project work, and experiments in self-modification; SWE-agent is research-oriented and also documents SWE-bench and EnIGMA workflows.
- SWE-agent's maintainers recommend mini-SWE-agent for new use; ouroboros's provided considerations instead emphasize setup, operational complexity, and reviewing its self-modification governance.
Choose ouroboros if you…
- want an agent to retain memory, history, and identity across tasks and restarts.
- need a desktop or headless agent that can work in external projects and coordinate specialist agents.
- want to explore reviewed self-modification or use a local GGUF model option.
Choose SWE-agent if you…
- want to study how language models use repository tools to attempt software issue fixes.
- need configurable workflows for coding tasks or SWE-bench evaluation.
- want to explore the documented EnIGMA cybersecurity mode, using version 0.7 while its 1.0 update is pending.
