# Workers Analytics Engine

Last updated Aug 25, 2026|Copy as Markdown|[View as Markdown](https://sm-rtk-allowlist-page.previews.developers.cloudflare.com/analytics/analytics-engine/index.md)|[Agent setup](https://sm-rtk-allowlist-page.previews.developers.cloudflare.com/agent-setup/)

Workers Analytics Engine provides unlimited-cardinality analytics at scale, via [a built-in API](https://sm-rtk-allowlist-page.previews.developers.cloudflare.com/analytics/analytics-engine/get-started/) to write data points from Workers, and a [SQL API](https://sm-rtk-allowlist-page.previews.developers.cloudflare.com/analytics/analytics-engine/sql-api/) to query that data.

You can use Workers Analytics Engine to:

* Expose custom analytics to your own customers
* Build usage-based billing systems
* Understand the health of your service on a per-customer or per-user basis
* Add instrumentation to frequently called code paths, without impacting performance or overwhelming external analytics systems with events
