We just shipped the new librefang.ai — a complete redesign of the official website for LibreFang, our open-source Agent Operating System built in Rust.
If you haven't heard of LibreFang: it's a production-grade runtime for autonomous AI agents. Single binary, 180ms cold start, 40MB memory. 15 built-in autonomous capability units ("Hands"), 44 channel adapters, 50 LLM providers. It runs agents 24/7 on a schedule — no user prompts needed.
Here's what we built for the new site.
7 languages, day one
The site ships with full translations in English, 简体中文, 繁體中文, 日本語, 한국어, Deutsch, and Español. Not machine-translated placeholders — every string was reviewed for grammar and natural phrasing.
Language detection is automatic based on your browser, and you can switch anytime from the nav.
Architecture visualized
The homepage walks through LibreFang's five-layer architecture:
- Channels — 44 adapters: Telegram, Slack, Discord, WhatsApp, Signal, Matrix, Teams, and more
- Hands — 15 autonomous units, each with its own model, tools, and workflow
- Kernel — agent lifecycle, workflow orchestration, budget control, scheduling
- Runtime — Tokio async, WASM sandbox, Merkle audit chain, SSRF protection
- Hardware — runs everywhere: laptop, VPS, Raspberry Pi, bare metal
Each layer is interactive — click to explore the components inside.
Performance benchmarks, not marketing claims
We put a comparison table right on the homepage:
| Metric | Others | LibreFang |
|---|---|---|
| Cold Start | 2.5 ~ 4s | 180ms |
| Idle Memory | 180 ~ 250MB | 40MB |
| Binary Size | 100 ~ 200MB | 32MB |
| Security Layers | 2 ~ 3 | 16 |
| Channel Adapters | 8 ~ 15 | 44 |
| Built-in Hands | 0 | 15 |
Rust, not TypeScript. Production, not prototype.
One command install with OS detection
The install section detects your OS automatically and shows the right command:
macOS / Linux:
curl -fsSL https://librefang.ai/install | sh
Windows (PowerShell):
irm https://librefang.ai/install.ps1 | iex
Tabs let you switch between macOS, Windows, and Linux manually too.
Downloads & changelog
The downloads section pulls release data in real-time through our own API proxy. Desktop apps, CLI binaries, everything categorized by platform.
The changelog page shows a full timeline of releases with:
- Category filters (features, fixes, etc.)
- Download counts per asset
- Auto-linked
#issuereferences and@usernamementions in release notes
Tech stack
- React + TypeScript + Vite
- Tailwind CSS for styling
- Framer Motion for animations
- TanStack Query for data fetching
- Cloudflare Workers for the GitHub stats proxy
No heavy frameworks. No CMS. Just a fast SPA that gets out of your way.
What's next
LibreFang itself is moving fast — WhatsApp bidirectional routing just landed, prompt versioning and A/B experiments are in, and we're working toward the v1.0 milestone.
The website will keep evolving with the project. Docs are at docs.librefang.ai, and the deploy page at deploy.librefang.ai has one-click options for Fly.io and more.
