Pirsch is a privacy-focused, cookie-free web analytics tool built around a server-side Go core, so traffic is measured through backend integration or lightweight scripts rather than client-side JavaScript that ad blockers can strip out. It ships as a drop-in Go package for developers who want analytics baked directly into their own applications, alongside a hosted dashboard offering event tracking, conversion goals, session breakdowns, and white-labeling for agencies managing client sites. Made and hosted in Germany, Pirsch is built to satisfy GDPR, CCPA, and PECR out of the box, and its open-source core can be self-hosted via a community proxy for teams wanting full infrastructure control.
