OpenFang
An open-source agent operating system, written in Rust, that runs autonomous agents on schedules around the clock rather than only responding to a typed prompt, compiling to a single binary.
OpenFang is an open-source operating system for autonomous agents, built from scratch in Rust rather than as a chatbot framework or a wrapper around a language model. It runs agents on schedules, continuously, building knowledge graphs, monitoring targets, generating leads, managing social media and reporting results to a dashboard.
Its core unit is the Hand, a pre-built autonomous capability package that runs independently on a schedule without being prompted. Each Hand bundles a manifest declaring its tools, settings and dashboard metrics, a multi-phase system prompt acting as an operational playbook, a skill reference with domain expertise, and guardrails that require approval before sensitive actions such as a purchase.
The entire system compiles to a single roughly 32MB binary, installed and started with one command. The project is pre-1.0 and still changing between minor versions, so its maintainers recommend pinning to a specific commit for production use.
