[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." 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>Windows</summary> ```powershell irm https://openfang.sh/install.ps1 | iex openfang init openfang start ``` </details> --- ## Hands: Agents That Actually Do Things "Traditional agents wait for you to type. Hands work for you." **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, so 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.

Every layer is independently testable and operates without a single point of failure. | # | System | What It Does | |---|--------|-------------| | 1 | **WASM Dual-Metered Sandbox** | Tool code runs in WebAssembly with fuel metering + epoch interruption. A watchdog thread kills runaway code. | | 2 | **Merkle Hash-Chain Audit Trail** | Every action is cryptographically linked to the previous one. Tamper with one entry and the entire chain breaks. | | 3 | **Information Flow Taint Tracking** | Labels propagate through execution. Secrets are tracked from source to sink. | | 4 | **Ed25519 Signed Agent Manifests** | Every agent identity and capability set is cryptographically signed. | | 5 | **SSRF Protection** | Blocks private IPs, cloud metadata endpoints, and DNS rebinding attacks. | | 6 | **Secret Zeroization** | `Zeroizing<String>` auto-wipes API keys from memory the instant they're no longer needed. | | 7 | **OFP Mutual Authentication** | HMAC-SHA256 nonce-based, constant-time verification for P2P networking. | | 8 | **Capability Gates** | Role based access control. Agents declare required tools, the kernel enforces it. | | 9 | **Security Headers** | CSP, X-Frame-Options, HSTS, X-Content-Type-Options on every response. | | 10 | **Health Endpoint Redaction** | Public health check returns minimal info. Full diagnostics require authentication. | | 11 | **Subprocess Sandbox** | `env_clear()` + selective variable passthrough. Process tree isolation with cross-platform kill. | | 12 | **Prompt Injection Scanner** | Detects override attempts, data exfiltration patterns, and shell reference injection in skills. | | 13 | **Loop Guard** | SHA256-based tool call loop detection with circuit breaker. Handles ping-pong patterns. | | 14 | **Session Repair** | 7-phase message history validation and automatic recovery from corruption. | | 15 | **Path Traversal Prevention** | Canonicalization with symlink escape prevention. ``../`` doesn't work here. | | 16 | **GCRA Rate Limiter** | Cost-aware token bucket rate limiting with per-IP tracking and stale cleanup. | --- ## Architecture 14 Rust crates. 137,728 lines of code.

No Meta Business account required. ### Prerequisites - **Node.js >= 18** installed ([download](https://nodejs.org/)) - OpenFang installed and initialized ### Setup **1. Install the gateway dependencies:** ```bash cd packages/whatsapp-gateway npm install ``` **2. Configure `config.toml`:** ```toml [channels.whatsapp] mode = "web" default_agent = "assistant" ``` **3. Set the gateway URL (choose one):** Add to your shell profile for persistence: ```bash # macOS / Linux echo 'export WHATSAPP_WEB_GATEWAY_URL="http://127.0.0.1:3009"' >> ~/.zshrc source ~/.zshrc ``` Or set it inline when starting the gateway: ```bash export WHATSAPP_WEB_GATEWAY_URL="http://127.0.0.1:3009" ``` **4. Start the gateway:** ```bash node packages/whatsapp-gateway/index.js ``` The gateway listens on port `3009` by default. Override with `WHATSAPP_GATEWAY_PORT`. **5. Start OpenFang:** ```bash openfang start # Dashboard at http://localhost:4200 ``` **6. Scan the QR code:** Open the dashboard → **Channels** → **WhatsApp**. A QR code will appear. Scan it with your phone: > **WhatsApp** → **Settings** → **Linked Devices** → **Link a Device** Once scanned, the status changes to `connected` and incoming messages are routed to your configured agent. ### Gateway Environment Variables | Variable | Description | Default | |----------|-------------|---------| | `WHATSAPP_WEB_GATEWAY_URL` | Gateway URL for OpenFang to connect to | _(empty = disabled)_ | | `WHATSAPP_GATEWAY_PORT` | Port the gateway listens on | `3009` | | `OPENFANG_URL` | OpenFang API URL the gateway reports to | `http://127.0.0.1:4200` | | `OPENFANG_DEFAULT_AGENT` | Agent that handles incoming messages | `assistant` | ### Gateway API Endpoints | Method | Route | Description | |--------|-------|-------------| | `POST` | `/login/start` | Generate QR code (returns base64 PNG) | | `GET` | `/login/status` | Connection status (`disconnected`, `qr_ready`, `connected`) | | `POST` | `/message/send` | Send a message (`{ "to": "5511999999999", "text": "Hello" }`) | | `GET` | `/health` | Health check | ### Alternative: WhatsApp Cloud API For production workloads, use the [WhatsApp Cloud API](https://developers.facebook.com/docs/whatsapp/cloud-api) with a Meta Business account. See the [Cloud API configuration docs](https://openfang.sh/docs/channels/whatsapp). --- ## 27 LLM Providers, 123+ Models 3 native drivers (Anthropic, Gemini, OpenAI-compatible) route to 27 providers: Anthropic, Gemini, OpenAI, Groq, DeepSeek, OpenRouter, Together, Mistral, Fireworks, Cohere, Perplexity, xAI, AI21, Cerebras, SambaNova, HuggingFace, Replicate, Ollama, vLLM, LM Studio, Qwen, MiniMax, Zhipu, Moonshot, Qianfan, Bedrock, and more. Intelligent routing with task complexity scoring, automatic fallback, cost tracking, and per-model pricing. --- ## Migrate from OpenClaw Already running OpenClaw? One command: ```bash # Migrate everything: agents, memory, skills, configs. openfang migrate --from openclaw # Migrate from a specific path openfang migrate --from openclaw --path ~/.openclaw # Dry run first to see what would change openfang migrate --from openclaw --dry-run ``` The migration engine imports your agents, conversation history, skills, and configuration. OpenFang reads SKILL.md natively and is compatible with the ClawHub marketplace. --- ## OpenAI-Compatible API Drop-in replacement. Point your existing tools at OpenFang: ```bash curl -X POST localhost:4200/v1/chat/completions \ -H "Content-Type: application/json" \ -d '{ "model": "researcher", "messages": [{"role": "user", "content": "Analyze Q4 market trends"}], "stream": true }' ``` 140+ REST/WS/SSE endpoints covering agents, memory, workflows, channels, models, skills, A2A, Hands, and more. --- ## Quick Start ```bash # 1.
