Open-source analytics platform covering web traffic, custom events, funnels, retention, session replay, and revenue tracking. GDPR-compliant with optional self-hosting.

OpenPanel tracks website visitors and product behavior in one place. You get standard web analytics (visitors, referrers, page views) alongside deeper product analytics: custom events, user profiles, funnel conversion, retention cohorts, and session replay. No cookies, no sampling, no data limits.
Session replay lets you watch real user sessions with privacy controls built in. Revenue tracking connects payment events to MRR and shows which referrers drive actual revenue. Google Search Console data pulls in alongside your product metrics, so you can see which queries convert.
There's also an MCP integration that connects your analytics data to AI tools like Claude or Cursor. Instead of building charts manually, you can query funnels, retention, and traffic breakdowns directly through an AI agent.
Tracking is cookie-less, IPs and user agents are hashed daily, and no fingerprinting is used. Data is EU-hosted on the cloud plan, and a Data Processing Agreement is available. Self-hosting gives you full control over data storage and retention. Unlike tools like Matomo or OpenReplay, OpenPanel bundles web analytics, session replay, and revenue tracking under one roof without bolt-on modules.
Pricing is event-volume-based with no limits on websites, users, dashboards, or tracked profiles. A 30-day free trial requires no credit card. Self-hosting is free with unlimited events.
