Lumtera 1.3.0 · Lumtera Pro 1.2.0

Find and fix accessibility problems while you write, and on the live page.

Lumtera checks your posts, pages and products against WCAG 2.2 level A and AA as you write, and checks the rendered page, keyboard and widgets included. Each issue is explained in plain words. Fixes are shown before they are saved, and every one can be undone. Lumtera is not an overlay: it adds nothing for visitors unless you turn on site fixes or the feedback form. It helps you fix the content itself.

Honest by design

With review mode's whole-page checks, Lumtera's automated checks cover 38 of 55 WCAG 2.2 A and AA criteria (1 fully, 37 in part). The checks of saved content alone cover 26 of 55. Covering a criterion means a check looks at it, not that your site meets it. The rest need a person, and the guided checklists walk you through them. A score of 100 in Lumtera means "no automated issues found", never "compliant". What automated testing can't do → · How accurate is Lumtera? →
