Workers Analytics Engine

Analytics Engine is a write-from-Workers time-series store you query with SQL over HTTP. Write a data point per event (with dimensions and metrics), then slice it however you like later. It’s cheap, it scales without thought, and it fills the “I want metrics about my thing without running a metrics stack” niche perfectly.

It fits per-customer usage counters, feature adoption tracking, and internal dashboards fronted by Grafana — the SQL API plugs into anything.

The catch you must understand before trusting the numbers: it uses adaptive sampling at high volumes, and queries return sampled estimates with a sample interval you’re expected to multiply through. That’s fine for trends and dashboards, wrong for billing-grade counts. Add the fixed retention window and a dashboarding story that’s entirely DIY, and it stays a 7 — but a 7 I’m genuinely fond of.
