A pencil sketch of a wislr performance report: a score of 96, a bar for each key page against a target line, and an Export PDF button.

Measure. Compare. Improve.

Every key page, on desktop and mobile, with lab tests and real-user data. Before and after every release. Findings your developers can act on the same day.

Two sources, one report

Lab Tests and Real Users, Side by Side.

Lab tools tell you what a page does under controlled conditions. Field data tells you what your visitors actually experienced in Chrome over the last 28 days. Most reports show one or the other. Ours put both next to each other for every page, so a green lab score never hides a red field result.

How it works

Nothing to Install. Nothing to Slow Down.

We measure from the outside, the way Google does. Your site stays exactly as it is.

ZeroSetup

No tags, no scripts, no access to your codebase. Send us the URLs that matter and the first report is on its way.

2Data Sources

Lighthouse lab runs plus Core Web Vitals from real Chrome users, for every page, on desktop and mobile.

EveryRelease Compared

Run a baseline, ship, run again. The comparison shows exactly what moved and by how much, page by page.

STEP 1

Pick the Pages That Matter.

Home, category, product, cart, checkout. Usually five to ten URLs that carry the business.

STEP 2

We Measure on a Schedule and Around Each Release.

A baseline first, then before and after every deployment, then monthly so nothing drifts unnoticed.

STEP 3

You Read It in Your Portal, We Walk Through It Together.

Reports land in your private wislr.io space within a day, with a summary up top and the detail underneath.
