• (2025-03-12) Haley Anderton-Folmer: This is such a downgrade from the last version that is now deprecated and still listed (but no longer downloadable) in the store. Because this doesn't check as thoroughly, I have to log into SI and do a single page check for all pages, not just new pages.
• (2025-03-03) ETech Buy (ETechBuy): It's really time saving and organized!
• (2024-07-02) Katarina Đurđević: Super easy, intuitive and organized!
• (2024-03-20) Ralf Longwitz: I have used it on a few sites today, and found it easy to use and very useful. I only wanted to check contrast, and now found a few other issues as well. Great.
• (2023-05-15) Carolina Aguilera: Antes aportaba información de calidad al hacer la revisión y ahora la experiencia usuaria con la interfaz de la extensión al activarla es horrible. ¿Qué sucedió en esta nueva versión? Se fue eliminada de mis herramientas de revisión de accesibilidad. Fuiste bueno Siteimprove.
• (2023-04-16) Earl W: V1 was good. This version does not work well, and I don't use it because the errors do not load for me. I only see the Spinner which does not stop. I quit after 40 seconds.. I with they would go back to version 1 so I can use this again, but for now I'll pass.

• (2023-01-09) Christopher Sheldon: I really liked v1.x but I have noticed that v2 has obvious errors and things it is not finding in pages. It is beyond the rules being refined in this version. One example that made me take notice was a page that had dark grey text on a darker grey background that was obviously a contrast fail, followed by a dark blue "Read more" link that also was an obvious fail. The extension only called out the grey on grey and didn't seem to notice the blue on grey fail in an anchor adjacent to the grey text for any issues. When manually checked the contrast was below the 4.5 ratio so failed AA and AAA contrast guidelines, possibly also AA and AAA Link Purpose. Finding these errors in the extension has shown me it is not as reliable as the previous version at finding issues. Be careful if you are using it to scan your site as it could be missing obvious fails.

• (2022-08-11) Thomas IX Days: Hello, I can't find documentation if this plug-in works at checking ADA accessibility for mobile devices if I use the plugin while using the developer tools (Responsive Views) on a Chrome browser. It's been frustrating find information about this.

• (2022-05-18) I love that this exists! As a UX designer I am always looking for quick simple ways to check accessibility and this does the trick! Couldn't recommend it enough.
• (2022-01-04) Alina B: Great extension. It helped to make rough initial assessment of our website.

• (2021-12-03) Ren Tyler: This used to be my favorite checker. Happily would've given 5 stars. Now... -1 star for no more side panel. -1 star for being colossally slow to check sites. Tested several. I closed after 15 seconds of getting no details. Used to be near instantaneous results. -1 star for having to even deduct stars in the first place.

• (2021-08-27) Robert Moore: Version 1 would retain your settings, v2 has to be rebuilt for every use. As mentioned earlier, 2.4.7 Focus Visible and 2.4.4 Link Purpose are not being discovered in v2.

• (2021-05-28) Jeff Leombruno: Unfortunately version 2.0 doesn't seem to return all the same errors that my coworkers with v127 see. Specifically v2 is not returning errors about 2.4.7 Focus Visible and 2.4.4 Link Purpose on a page where my coworkers see those errors using the older version of the extension.

• (2021-05-08) Jurjen de Vries: I really like the extension because it is helping a lot to optimize sites with WCAG norms so a broader audience is able to surf the web. But for me it also worked better as a sidebar of the page as we had in the previous version. What about a configuration switch in the settings so we as end-users can decide if we want it as sidebar or on a separate page?

• (2021-05-03) Carlos Izquierdo: Antes era una buena ayuda para auditar la accesibilidad de una página web, ahora, esta nueva versión es un asco. Me dedico a auditar la accesibilidad de sitios web y compruebo muestras de 35 páginas simultáneamente y que se abriera la extensión a un lado de la ventana no estaba mal, ahora es una ventana emergente que a veces sale y otras no. Además cuando sale me obliga a abrir y cerrar la ventana cada vez que cambio de pestaña porque no se sabe a cual de todas se refiera. Esta nueva versión no aporta nada nuevo pero sí que empeora la experiencia de usuario, ¡Por Dios! vuelvan a la versión anterior, esta es inusable.
