Frequently asked questions
Who is Axe DevTools Linter for?
The Axe DevTools Linter is for teams of developers who want to automatically have their source code checked for accessibility violations in real time. 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 or can be accessed locally on the developers machine.
How does Axe DevTools Linter work?
Axe DevTools Linter scans your static code and provides instant feedback on accessibility issues while you code—like a spellchecker for accessibility. You can use it to run an automated check as part of a pull request (PR) and block obvious accessibility defects from being merged into the code.
How is Axe DevTools Linter licensed?
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 refers to lines of code that are inspected with our linter.
Are there any free accessibility linters available?
Yes! We offer a free personal edition linter called Axe Accessibility Linter for VS Code for developers to automatically check the accessibility of their code while they type. It’s purpose-built to test your static code for accessibility. The Axe Accessibility Linter for VS Code as of October 2025 has more than 600k downloads on the Visual Studio marketplace.
