Independent measurement

Inspect providers, files, transfer size and main-thread work

Differences and pricing

PSI is a laboratory mobile test, so advertising, geography, cache and external server response can change the figures. Compare several runs under similar conditions and verify functionality manually.

info is the number of unique providers; the total is their file count. The base price covers three integrations on the submitted URL. PSI retains the full list. If confirmed, you can order third-party optimization.
