Ouroboros
OpenFang is a Rust-built Agent OS shipping as a single 32MB binary with autonomous 'Hands' that run scheduled tasks without prompting. It's pre-1.0 but battle-tested with 2,696+ passing tests and active security audits, aiming to be an autonomous agent platform rather than a chatbot.
A self-modifying AI agent that rewrites its own mind and evolves autonomously with a constitution and persistent identity. Ships as a native desktop app with local model support, layered safety, and a community skills marketplace.
