Frequently asked questions

The axe DevTools Linter is used by teams of developers who want to automatically have their source code checked for accessibility violations. We have 44 accessibility rules that check your code in your CI/CD system, provide reports or provide the results back to your code collaboration system such as GitHub. Additionally, reports can be sent to SonarQube.

It’s now possible to run an automated check as part of a pull request (PR) and block obvious accessibility defects from being merged into the code. Another common practice in agile development is to collect quality, compliance, and tech-debt metrics as part of the continuous integration (CI) process and to show it on a dashboard for everyone to see. Now, with no additional work on the part of the team, you can include accessibility issues in those metrics. This allows code accessibility to be treated as it should be– another standard aspect of software quality.

Axe DevTools Linter can be licensed as a stand-alone product or as a component within the axe DevTools product suite. The licensing model fees are based on actual server usage which we track using a metric we call LoC – which stands for lines of code that are inspected with our linter.
