The Agent
Operating System
Open-source Agent OS built in Rust. 7 autonomous Hands that run on schedules, build knowledge graphs, and report to your dashboard. 30 agents, 40 channels, 38 tools, 26 LLM providers. 16 security systems. One binary.
14 crates. 137K lines of Rust. Zero clippy warnings. Production-ready.

What OpenFang Does
The core primitives for building, running, and deploying autonomous agents.
7 Autonomous Capability Packages
Pre-built agents that work FOR you. Clip turns video into shorts. Lead generates qualified leads. Collector monitors targets. Predictor forecasts with Brier scores. Researcher fact-checks with CRAAP. Twitter manages your X account. Browser automates the web. Activate, configure, check your dashboard.
16 Security Systems
WASM dual-metered sandbox, Ed25519 manifest signing, Merkle audit trail, taint tracking, SSRF protection, secret zeroization, HMAC-SHA256 mutual auth, GCRA rate limiter, subprocess isolation, prompt injection scanner, path traversal prevention, and more.
Sandboxed Execution
Tool code runs inside WASM with dual metering (fuel + epoch interruption). File operations are workspace-confined. Subprocesses are env-cleared and timeout-enforced. 10-phase graceful shutdown.
30 Pre-Built Agents
From orchestrators to code reviewers to customer support. Four performance tiers across Anthropic, Gemini, Groq, and DeepSeek. Spawn one in a single command.
38 Built-In Tools + MCP
38 native tools plus Model Context Protocol client and server. Connect external MCP servers and expose OpenFang tools to other agents. Includes web search, browser automation, image generation, TTS, Docker, knowledge graphs.
Persistent Memory
SQLite-backed storage with vector embeddings. Cross-channel canonical sessions, automatic LLM-based compaction, and JSONL session mirroring. Agents recall context across conversations and channels.
40 Channel Adapters
Telegram, Discord, Slack, WhatsApp, Teams, IRC, Matrix, and 33 more. Per-channel model overrides, DM/group policies, rate limiting, and output formatting. One agent, every platform.
MCP + A2A + OFP
Model Context Protocol (client + server), Google A2A agent-to-agent tasks, and OpenFang Protocol for P2P networking with HMAC-SHA256 mutual authentication. Your agents talk to the world.
Tauri 2.0 Native App
Native desktop application with system tray, notifications, single-instance enforcement, auto-start on login, and global shortcuts. Full dashboard in a native window.
OpenFang vs The Landscape
6 frameworks. 10 dimensions. See how OpenFang's kernel-grade Rust architecture compares to OpenClaw, ZeroClaw, CrewAI, AutoGen, and LangGraph.
Measured, Not Marketed
Cold start time, memory footprint, install size, security depth, channel coverage, and provider support — benchmarked across 6 leading agent frameworks.
Agents That Work For You
Hands are pre-built autonomous capability packages. Unlike regular agents you chat with, Hands run on schedules, build knowledge graphs, and report results to your dashboard. Activate one and check in on its progress.
Traditional agents wait for you to type. Hands work for you.
Each Hand bundles a HAND.toml manifest, system prompt with multi-phase operational playbook, SKILL.md expert knowledge, configurable settings, and dashboard metrics — all compiled into the binary at build time.
Clip
ContentTurns long-form video into viral short clips with captions, thumbnails, and optional AI voice-overs. Publishes to Telegram and WhatsApp.
Lead
DataAutonomous lead generation. Discovers, enriches, scores, and deduplicates qualified leads on a daily schedule. Builds ICP profiles and knowledge graphs.
Collector
IntelligenceOSINT-style intelligence collector. Monitors any target continuously with change detection, sentiment tracking, and knowledge graph construction.
Predictor
ForecastingSuperforecasting engine. Collects signals, builds calibrated reasoning chains, makes predictions, and tracks accuracy with Brier scores.
Researcher
ProductivityDeep autonomous researcher. Cross-references sources, fact-checks claims with CRAAP evaluation, and generates cited reports in multiple languages.
Autonomous Twitter/X manager. Creates content in 7 rotating formats, schedules posts, engages with mentions, and tracks performance metrics.
Browser
AutomationWeb automation agent. Navigates sites, fills forms, clicks buttons, and completes multi-step workflows. Mandatory purchase approval gate.
Build Your Own
Define a HAND.toml with tools, settings, requirements, and a system prompt. Publish to FangHub.
