Speed and quality

Speed, mobile and accessibility checks

Fast, usable on a phone, and usable by everyone.

A page that feels fine on your laptop can take ten seconds on a phone, hide its buy button off-screen, or be impossible to use with a keyboard. Each of those costs visitors on the day you can least afford it.

These agents find oversized images, heavy JavaScript, layouts that break on narrow screens, and forms without labels. They report the cause in the code and the change that fixes it.

Some of what it looks for

  • MOB-01highThe viewport tag is missing, so phones show a tiny desktop page
  • BUNDLE-01mediumA heavy library is loaded on every page when it is needed on one, or not at all
  • BUNDLE-02mediumA whole library is imported to use one function
  • BUNDLE-03mediumLarge components (charts, editors, maps, 3D) load up front instead of on demand
  • BUNDLE-04mediumServer-only code or large data files end up in the browser bundle
  • MOB-02mediumContent is wider than the screen and the page scrolls sideways
  • MOB-03mediumThe navigation has no phone version
  • MOB-04mediumButtons and links are too small or too close together to tap

The agents that do the work

  • speed-checker

    Finds what makes a site slow to load and slow to respond: heavy images, oversized JavaScript, render-blocking scripts, fonts and uncached pages.

  • accessibility-checker

    Checks a site for common barriers to people using a keyboard, a screen reader or with low vision: missing labels, poor contrast, hidden focus, clickable divs and inaccessible pop-ups.

  • mobile-checker

    Checks that a site works on phones: viewport, layouts that fit narrow screens, tap targets, readable text and usable forms.
