Run AI agents with OpenFang, an open-source operating system project for agent workflows.
About OpenFang
OpenFang is an open-source agent operating system written in Rust and distributed from a GitHub repository. Rather than waiting for typed prompts, it runs autonomous agents on schedules, 24/7, doing work such as building knowledge graphs, monitoring targets, generating leads, managing social media and reporting to a local dashboard. The whole system compiles to a single roughly 32MB binary that installs with one command, and it ships with pre-built "Hands" capability packages that bundle tools, multi-phase prompts, domain skill references and approval guardrails.
Key features
- Autonomous agents run on schedules, 24/7, without prompting
- Bundled Hands package manifests, playbooks, skill references and approval guardrails
- Clip: turns YouTube URLs into captioned vertical shorts with thumbnails
- Lead: discovers, enriches, scores and deduplicates prospects; exports CSV/JSON/Markdown
- Collector: continuous target monitoring with change detection and sentiment tracking
- Predictor and Researcher: calibrated forecasts, confidence intervals and cited reports
Best for: Developers and teams who want to self-host scheduled, autonomous agent workflows from an open-source Rust codebase.

Run the install script via curl on Unix-like systems or irm on Windows, then run openfang init and openfang start. The dashboard is served at http://localhost:4200.
What are Hands in OpenFang?
Hands are pre-built autonomous capability packages that run on schedules. Each bundles a HAND.toml manifest, a multi-phase system prompt, a SKILL.md expertise reference and guardrails such as approval gates for sensitive actions, all compiled into the binary.
