There’s no shortage of web accessibility testing tools, however there are currently none that I know of that do all of the following: * provide immediate, up-to-date feedback on issues created by the code that I’m writing; * make that feedback really hard to ignore; * scan the rendered page (as opposed to the source code).

So I built Accented, an open-source tool that satisfies all of the above criteria.

You can read more about what it does and how it’s different from other approaches at https://accented.dev/blog/2025-07-16-introducing-accented/

Here’s also a playground where you can poke around without installing anything: https://stackblitz.com/edit/accented-playground-react-ts?fil...
