What each one is
SWE-agent
SWE-agent from Princeton turns an LLM into an autonomous agent that fixes bugs in real GitHub repositories using a purpose-built agent-computer interface.
- Strong results on SWE-bench
- Purpose-built agent-computer interface
- Research-grade and reproducible
Agent Zero
Agent Zero is a fully transparent personal agent framework: it writes and executes code in its own Linux environment, spawns sub-agents, and every behavior is a prompt you can change.
- Everything is a prompt — completely customizable
- Executes real code in an isolated environment
- Hierarchical sub-agents keep context clean
