Buyer's guide

How to choose tools for digital accessibility

No single tool makes a website accessible. An automatic scanner finds some of the problems quickly. A widget lets visitors adjust the page. Developer tools catch errors before they are published, and an expert review assesses flows with assistive technology. Most organisations need a combination.

Comparison

Four types of tools

  • Automatic scanner

    What it does
    Finds recurring technical problems in seconds and sorts them by severity
    What it does not do
    Does not assess flows, content or how the page works with assistive technology
    Right when
    You want a first picture or to follow up continuously
  • Accessibility widget

    What it does
    Lets visitors adjust text, contrast and reading
    What it does not do
    Does not fix errors in the code and does not replace fixing them
    Right when
    You want to support visitors while you fix things
  • Developer tools (API, integrations)

    What it does
    Catches errors in the development workflow before they are published
    What it does not do
    Does not cover content that is already published without an audit
    Right when
    You develop and release often
  • Expert review and user testing

    What it does
    An expert tests key pages and flows against WCAG with assistive technology
    What it does not do

Questions to ask the vendor

The answers quickly show whether the tool suits you and what help you get.

  • Which WCAG criteria does the tool test automatically, and which need a manual check?
  • What does the report look like, and who in our organisation is it written for?
  • How do we check that the problems actually get fixed?
  • What is included in the price, and what does it cost to grow in number of pages or domains?
  • Who helps us when the tool is not enough?

Common questions about accessibility tools

Is an automatic tool enough?
No. Automatic tests do not find every problem and need to be complemented by manual testing. A scan alone does not show that you meet the law.

Which standard should the tool measure against?
EN 301 549, which builds on WCAG 2.1 level A and AA.

Can a widget be the whole solution?
No. A widget can be a good complement that helps visitors make personal choices, improves keyboard navigation and makes things easier for screen readers by adapting the HTML for the visitor, but it does not fix errors in the source code. Make sure to test a widget manually and to compare vendors.
