[Report issues here.](https://github.com/RightNow-AI/openfang/issues) --- ## What is OpenFang? OpenFang is an **open-source Agent Operating System** — not a chatbot framework, not a Python wrapper around an LLM, not a "multi-agent orchestrator." It is a full operating system for autonomous agents, built from scratch in Rust. Traditional agent frameworks wait for you to type something. OpenFang runs **autonomous agents that work for you** — on schedules, 24/7, building knowledge graphs, monitoring targets, generating leads, managing your social media, and reporting results to your dashboard. The entire system compiles to a **single ~32MB binary**. One install, one command, your agents are live. ```bash curl -fsSL https://openfang.sh/install | sh openfang init openfang start # Dashboard live at http://localhost:4200 ``` <details> <summary><strong>Windows</strong></summary> ```powershell irm https://openfang.sh/install.ps1 | iex openfang init openfang start ``` </details> --- ## Hands: Agents That Actually Do Things <p align="center"><em>"Traditional agents wait for you to type. Hands work <strong>for</strong> you."</em></p> **Hands** are OpenFang's core innovation — pre-built autonomous capability packages that run independently, on schedules, without you having to prompt them. This is not a chatbot. This is an agent that wakes up at 6 AM, researches your competitors, builds a knowledge graph, scores the findings, and delivers a report to your Telegram before you've had coffee. Each Hand bundles: - **HAND.toml** — Manifest declaring tools, settings, requirements, and dashboard metrics - **System Prompt** — Multi-phase operational playbook (not a one-liner — these are 500+ word expert procedures) - **SKILL.md** — Domain expertise reference injected into context at runtime - **Guardrails** — Approval gates for sensitive actions (e.g. Browser Hand requires approval before any purchase) All compiled into the binary. No downloading, no pip install, no Docker pull. ### The 7 Bundled Hands | Hand | What It Actually Does | |------|----------------------| | **Clip** | Takes a YouTube URL, downloads it, identifies the best moments, cuts them into vertical shorts with captions and thumbnails, optionally adds AI voice-over, and publishes to Telegram and WhatsApp. 8-phase pipeline. FFmpeg + yt-dlp + 5 STT backends. | | **Lead** | Runs daily. Discovers prospects matching your ICP, enriches them with web research, scores 0-100, deduplicates against your existing database, and delivers qualified leads in CSV/JSON/Markdown. Builds ICP profiles over time. | | **Collector** | OSINT-grade intelligence. You give it a target (company, person, topic). It monitors continuously — change detection, sentiment tracking, knowledge graph construction, and critical alerts when something important shifts. | | **Predictor** | Superforecasting engine. Collects signals from multiple sources, builds calibrated reasoning chains, makes predictions with confidence intervals, and tracks its own accuracy using Brier scores. Has a contrarian mode that deliberately argues against consensus. | | **Researcher** | Deep autonomous researcher. Cross-references multiple sources, evaluates credibility using CRAAP criteria (Currency, Relevance, Authority, Accuracy, Purpose), generates cited reports with APA formatting, supports multiple languages. | | **Twitter** | Autonomous Twitter/X account manager. Creates content in 7 rotating formats, schedules posts for optimal engagement, responds to mentions, tracks performance metrics. Has an approval queue — nothing posts without your OK. | | **Browser** | Web automation agent. Navigates sites, fills forms, clicks buttons, handles multi-step workflows. Uses Playwright bridge with session persistence. **Mandatory purchase approval gate** — it will never spend your money without explicit confirmation. | ```bash # Activate the Researcher Hand — it starts working immediately openfang hand activate researcher # Check its progress anytime openfang hand status researcher # Activate lead generation on a daily schedule openfang hand activate lead # Pause without losing state openfang hand pause lead # See all available Hands openfang hand list ``` **Build your own.** Define a `HAND.toml` with tools, settings, and a system prompt.
