Is your website visible?

Visible is a tool-chain that helps developers to build websites in the perspective of accessibility


Less pain, more accessible

Visible is not just a linter, we also provide information on how to make your website accessible. We indicate which part you need to fix, give you patches of codes, give you references to the standards — to help you to learn and improve the accessibility of your website.

Visible is also available on command-line, so you can use it on continuous integrations services and monitor the website is fine.
