Koa11y: Open-Source Accessibility Testing Tool

Discover Koa11y, an open-source accessibility testing tool for websites, scanning web pages and highlighting issues to make the site usable by everyone

What is Koa11y?

Koa11y is an open-source web accessibility testing tool. It is designed to help developers and web designers identify accessibility issues on their websites.

Koa11y scans web pages and highlights potential problems that could make the site difficult or impossible to use for people with disabilities. This includes issues like:

  • Missing alternative text for images
  • Low color contrast that makes text hard to read
  • Lack of ARIA labels for interactive elements
  • Videos without captions
  • Non-semantic markup that is confusing for screen readers

After scanning a page, Koa11y generates a report showing all the flagged issues. Each one includes a description of the problem and suggestions for fixing it. There are also handy filters to sort issues by type or severity.

As an open source tool, Koa11y is free for anyone to use. It can be installed as a browser extension or used as an online webapp. The code is available on GitHub for developers wanting to contribute and improve the project.

While Koa11y doesn't catch every single accessibility issue, it is extremely helpful for catching common problems. Both developers and accessibility testers can use it as part of their overall workflow for ensuring websites are usable for all visitors.
