Liwan

Liwan is an open source web analytics platform designed for site owners who want to monitor visitor activity while maintaining strict privacy standards. It operates as a single, self-contained binary that runs on user-controlled infrastructure, eliminating reliance on third-party services or cloud vendors. The platform tracks essential metrics including page views, visitor groups, and referral sources while filtering common bot traffic automatically. It delivers real-time dashboard updates and requires minimal computational resources, running efficiently on budget VPS instances, older hardware, or single-board computers. Built in Rust with async I/O support, the project is available under an Apache 2.0 license and can be extended or modified by users.
