What is openfang?
OpenFang is an open-source agent operating system built from scratch in Rust. Instead of waiting for user input, it runs autonomous agents around the clock on a schedule to build knowledge graphs, monitor targets, find potential customers, and report results to a dashboard. It packs 7 autonomous capability packages (Hands), 30 agents, 40 channels, 38 tools, 26 LLM providers, and 16 security systems into a single binary of about 32MB. It notes that it is still pre-1.0, so compatibility may break between minor versions.
