## 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
```

## 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, 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. Publish to FangHub.

## 16 Security Systems: Defense in Depth
OpenFang doesn't bolt security on after the fact. 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. |

## WhatsApp Web Gateway (QR Code)
Connect your personal WhatsApp account to OpenFang via QR code, just like WhatsApp Web. 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).

## Stability Notice
OpenFang v0.5.10 is pre-1.0. The architecture is solid, the test suite is comprehensive, and the security model is deep. That said:
- **Breaking changes** may occur between minor versions until v1.0.
- **Some Hands** are more mature than others. Browser and Researcher are the most battle tested.
- **Edge cases** exist. If you find one, [open an issue](https://github.com/RightNow-AI/openfang/issues).
- **Pin to a specific commit** for production deployments until v1.0.
We ship fast and fix fast. The goal is a rock solid v1.0 by mid 2026.
