How to choose

What should the platform scan?

Choose a platform whose scan scope matches the content you need to check.

Compare automated scans and standards coverage, then confirm that the tool addresses the kinds of digital content your team manages.

How will it fit into our issue workflow?

Look for issue workflows that fit how your team tracks and resolves accessibility problems.

Compare developer integrations and whether a public API is available if you need the platform to connect with other software.

Do we need continuous monitoring?

Choose continuous monitoring if you need checks to continue over time rather than relying on individual scans.

Compare monitoring with automated scan options and the scope each platform covers.

Which platforms can we use it on?

Check the listed platforms against where your team needs to run or access the tool.

The board includes web, API, self-hosted, Windows, Linux and extension options; confirm the specific fit before choosing.

How should we compare plans and prices?

Compare whether a free plan is available, the paid starting price and whether pricing is provided on request.

A free plan and a free trial are different, so check which option is listed and what it offers before deciding.
