Accessibility testing tool from TPGi
I have been using this testing tool for over 6 years. With each iteration over the years, the tool has improved. It has easily become my go to tool, and replaced all former tools that I used to use. I especially like the ability to test only a certain portion of a page, limiting the scope to just a particular node in the DOM. This allows me to focus on the part that I am interested in/working on, reducing the time it takes me to filter through all of the other results. Overall, a dependable tool.
It was one of the best tools. The last usable version was 4.3. The UX sucks. Mainly because I now have 2 more clicks for each functionality I want to use than in the previous version of the tool. Also, I have to ask myself every time which option to choose to test what I want. Before, everything was clear. After the last update (5.7.2), no matter which test topic I choose, all topics are tested after clicking the "Run tests" button.
A powerful extension that allows users to preview web pages and see what issues are present on the site in relation to WCAG recommendations. I would highly recommend as you can test before going live, even working on a local version of the page to see how it performs. The extension allows you to quickly find the specific code and test how to correct the issue within any environment.
