CowAgent vs. Ouroboros
CowAgent
Ouroboros
A massively popular open-source personal AI assistant and 'Agent Harness' that plans tasks, runs skills, and self-evolves with memory and knowledge. Multi-agent, multi-model, and multi-channel with a one-line install and an active skill hub.
A self-creating, self-rewriting AI agent with persistent identity and durable memory across restarts. It coordinates a swarm of specialist agents and can modify its own code, prompts, tools, and dependencies.
