Editoria11y (“editorial accessibility ally”) is a quality assurance tool built for an author’s workflow:
This plugin is the WordPress adaptation of the open-source Editoria11y library. Tests run in the browser and findings are stored in your own database; nothing is sent to any third party. It is meant to supplement, not replace, testing your code and visual design with developer-f…
This is such a fantastic, simple tool for helping editors write content, it’s incredible that it’s open source and free! I’ve never found such an intuitive, easy to understand, and easy to implement accessibility checker like this. Great work, I’ve already installed it on all of my latest projects, and I’ll continue to do so going forward. And I absolutely love the logging feature!
Can’t believe this only has 300 installs, I’ll definitely be spreading the word as much as I can!
I have used other accessibility checkers that cannot function properly outside of core and are crazy complicated. This work wonderfully in core, Bricks Builder, and even Avada (live builder). The reporting is easy to understand and the plugin is so lightweight. Thank you for this!
We’ve been using this plugin for a while. It’s a great asset for composing posts. The checks show up in real time as content is added to the editor, which is a huge help and reminder to write accessible content the first time around, rather than having to go back and fix badly presented content later.
I also appreciate that this checker focuses on the issues that an editor can actually control and excludes issues with navigation, headers, etc. While these other issues are important and deserve a look by an administrator or site designer, they would only be a distraction to someone editing a post.
I’ve experimented with installing similar tools like Tota11y, Sa11y, and the Equalize Digital Accessibility Checker, but this is the tool that has stuck for me because it feels the most approachable to less-experienced editors and it provides suggestions for fixing things.
The errors are helpfully focused on issues that editors can actually do something about, and I think it mostly gets the right balance of making errors appear urgent but not overwhelming.
Each error includes an explanation of why the issue is important and how to resolve it, so that editors can actually take action. And the ability to track issue resolutions overtime in the dashboard is fabulous!
My agency has been installing the Editoria11y javascript as part of a custom theme on every client site for months. I was delighted to discover it’s now available as an official plugin in the repository.
We build sites and train clients on how to enter and update content. Editoria11y Accessibility Checker is a fantastic training tool – it helps content editors see where accessibility problems exist in their content, and helps them figure out solutions and alternatives. Using the plugin is a no-brainer; editors see the alerts right in the web page next to the problem.
Even if you’re not concerned about accessibility (you should be), you can use this plugin to highlight issues that affect SEO, since accessibility is closely related to SEO.
We’re going to be using this plugin on every site for the foreseeable future. Thanks for building this!
