Prism Analytics
Privacy-first analytics platform with real-time dashboards, funnel analysis, and custom event tracking without cookies.
Prism is a privacy-first analytics platform designed as an alternative to Google Analytics for teams that care about user privacy. No cookies, no fingerprinting, no personal data collection. You still get the insights you need — page views, referrers, geography, device types, and custom events.
The tracking script is 1.2KB gzipped. It sends a single POST request per page view with anonymized data. We hash the IP + User-Agent + daily salt to generate a session identifier that's impossible to reverse and changes every 24 hours.
ClickHouse powers the analytics backend. Its columnar storage and vectorized query engine lets us aggregate millions of events in milliseconds. The real-time dashboard updates every 5 seconds using Server-Sent Events from a Go streaming service.
Funnel analysis was the most-requested feature. Define a sequence of events (visited pricing page, clicked sign up, completed form, activated account) and see where users drop off. The visualization uses D3.js for custom funnel charts that show conversion rates at each step.
