Frequently Asked Questions
Brief Summary
OpenFang is the first open-source Agent Operating System built entirely in Rust — not a chatbot wrapper, but a genuine OS that schedules autonomous agents 24/7, all in a single 32 MB binary with 180 ms cold start.
Seven pre-built 'Hands' wake up on cron schedules to research competitors, generate leads, monitor targets, and manage social media — completely without human prompting.
With 16 independent security layers including a WASM dual-metered sandbox, Merkle hash-chain audit trail, and Ed25519 signed manifests, OpenFang delivers enterprise-grade security that no other open-source agent framework even approaches.
Extended Summary
What if your AI agents kept working through the night — researching, prospecting, monitoring, and publishing — without you ever typing a command? OpenFang makes this real: an open-source Agent Operating System written in 137,000 lines of Rust that compiles to a single 32 MB binary, starts in 180 milliseconds, and idles at just 40 MB — making it 10× lighter than OpenClaw and 14× faster to start than LangGraph.
The defining innovation is 'Hands' — seven pre-built autonomous capability packages that run on cron schedules and deliver structured results to a dashboard: the Researcher fact-checks with CRAAP criteria, the Lead Hand scores and enriches B2B prospects daily, the Collector builds OSINT knowledge graphs continuously, and the Browser Hand automates web workflows with a mandatory purchase-approval gate.
Security is not an afterthought: 16 discrete defence layers include a WASM dual-metered sandbox that caps every tool call's compute budget, Ed25519 signed agent manifests that prevent supply-chain tampering, a Merkle hash-chain audit trail that makes log manipulation cryptographically impossible, and an always-on prompt injection scanner.
Deployment spans 40 channel adapters — Telegram, Discord, Teams, WhatsApp, Signal, Bluesky, Nostr, and 32 more — with cross-channel canonical sessions ensuring a unified user identity regardless of which platform they contact the agent through, and 27 LLM providers including free-tier Groq and fully local Ollama/LM Studio options.
OpenFang is pre-1.0 software targeting a rock-solid v1.0 by mid-2026, built primarily by one engineer at RightNow AI — a technical foundation and architectural vision that make it the most compelling open-source agent infrastructure released in 2026 for anyone building autonomous, always-on AI workloads.
