Privacy-First Web Analytics | Liwan | WarmIndex

Liwan is a lightweight, privacy-first, open-source web analytics platform that you self-host as a single binary, delivering real-time traffic insights without cookies, tracking, or third-party data sharing.

🚀 Overview

Liwan solves the privacy concerns of traditional analytics tools like Google Analytics by providing a self-hosted solution where all visitor data stays on your server—no cookies, no cross-site tracking, and no persistent identifiers.

It's built for developers, indie makers, website owners, and privacy-conscious teams who need accurate metrics on visitors, page views, referrers, and more, without compromising user trust or relying on cloud services.

The project was created to offer a fast, efficient alternative using Rust, runnable on minimal hardware like a Raspberry Pi, emphasizing open-source transparency and community contributions.

✨ Key Features

Quick setup: Single self-contained binary, no database needed; tiny <1KB tracking script works on any website
Privacy-first: No cookies or tracking; all data stored locally on your server (what's collected: IP hash, user agent, referrer, path, screen size, language—see /reference/data)
Lightweight: Runs on cheap VPS, old Mac Mini, or Raspberry Pi; Rust with Tokio for async I/O
Accurate data: Tracks visitors, page views, referrers; auto-detects and filters bots/crawlers
Real-time analytics: Dashboard updates live as traffic arrives
Open source: Apache 2.0 licensed for full customization
