Pirsch
Cookie-free server-side analytics with a clean Go-based architecture
Overview
Pirsch is a lightweight, cookie-free analytics solution that processes events server-side, avoiding ad-blockers entirely. It stores data in ClickHouse for high-throughput sites and exposes a simple REST API for custom integrations. The open-source core covers all essential metrics; a managed SaaS tier adds team collaboration and extended data retention.
Where it falls short of Google Analytics
- ClickHouse dependency raises the infrastructure bar considerably
- No built-in session replay or heatmap features
- Team/org management requires the commercial SaaS tier
We list the gaps honestly so you can decide if the trade-off is worth owning your data.
