This is the open-source core of Pirsch Analytics, a privacy-friendly web analytics solution. It originally started as an experiment to reliably analyze web traffic from the server-side using Go.
Pirsch is made in the EU 🇪🇺 and hosted on German 🇩🇪 owned servers at Hetzner. You can find an interactive demo of what the dashboard looks like today here.
Pirsch generates a unique fingerprint for each visitor. The fingerprint is a hash of the visitors IP address, User-Agent, the date, and a salt. The tracking works without invading the visitor's privacy. It doesn't use cookies and no personal information is stored, making it GDPR-, CCPA-, and PECR-compliant. If used on the server-side, Pirsch can track visitors using ad blockers.
