Visualization of website accessibility tree
When COVID-19 started I needed something to get busy to not go crazy. I happened to work on our app WCAG compliance for a few months at the time and was frustrated by the state of of accessibility-related tools for developers. I've spend two months delivering a tool that is easy to understand and helps catching accessibility issues on my apps. A few years later it's pretty popular despite being mostly abandoned. I will be happy to work on this further but honestly lost my enthusiasm some time ago. I'd love to get in touch with some company in the accessibility testing space and discuss how…
