We are building a library of recorded analytics script benchmarks — measured on real test pages, not estimated from marketing claims.
Coming soon
Most analytics comparisons repeat vendor claims about script weight. We are recording our own numbers instead — transfer size, decoded body size, and main-thread blocking time on controlled test pages with documented network and device conditions.
We will not publish a benchmark until a test is complete. Pending entries below are queued for measurement, not placeholders with guessed metrics.
These benchmarks are planned and awaiting controlled recording. No performance numbers are shown until testing is finished.

This benchmark is queued for controlled testing. We publish results only after recording transfer size, decoded weight, and main-thread blocking on a live test page — never estimated or vendor-claimed numbers.
Benchmarks are recorded by AnalyticsVS using controlled test pages. See /methodology for full details.
