Low- and Mid-Tier Mobile for the Real World (2025) – CSS Wizardry Discover the most representative low- and mid-tier mobile devices for web performance testing in 2025.

I added a section about making better device choices on @catchpointsystems.bsky.social’s #WebPageTest: csswizardry.com/2025/08/low-...

I’ve been afraid to enable the new UI for #WebPageTest because I wasn't certain I would be able to get back to the old UI.

But I took the leap today hoping I would find an easier way to run experiments blocking domains.

Has anyone else switched to the new UI yet? What is your impressions?
