OpenMetrics

Mixpanel and Amplitude charge per event and sample your data at scale. Google Analytics anonymizes everything. OpenMetrics is an open-source alternative that you host on your own infrastructure — full data ownership, no event caps, no black-box algorithms.

OpenMetrics ingests events via a JavaScript snippet or server-side SDK and stores them in your own Postgres or ClickHouse database. Query your raw events with SQL, build dashboards with a drag-and-drop UI, and set up automated reports — all without sending user data to a third-party vendor.

Why teams choose OpenMetrics

• Full data ownership: events stored in your database, not ours
• Zero sampling: every event is stored and queryable
• SQL access: write custom queries against raw event tables
• GDPR/CCPA compliant by design: you control what is collected and stored
• Open source: audit the code, extend it, self-host on a $10/month VPS
