Drill down into each issue, inspect the source of the problem and leverage extensive free remediation guidance to fix it quickly and accurately.

★ No False Positives Nobody has time to chase issues that aren’t actually issues. Axe DevTools reports only issues with absolute certainty. Other tools report irrelevant and inaccurate results, wasting your time, money, and productivity on rework.

★ The fastest and most effective path to accessible Using axe DevTools to proactively find and fix accessibility issues significantly reduces the need for manual testing, giving you quick and easy wins without disrupting your development velocity.

Upgrade to axe DevTools Pro to do so much more:

★ Intelligent Guided Testing™ (IGT) Perform more advanced testing without having to become an accessibility expert. Using a simple question and answer format, IGT leverages machine learning to help you quickly find and fix issues that are not detectable by automated testing alone. Adding IGT can get you 8o% coverage or more—while you code.

★ Component-level testing Make your testing more agile by focusing only on the specific parts of a page relevant to your immediate work. Reduce patching and retesting by finding accessibility bugs that could break existing use cases.

★ Export, Save and Share Collaborate across your dev team! With one click, create a customized URL with all issue description information to share with colleagues or your issue tracking software of choice. Save the rest of your team time and effort and help them build inclusive experiences.

★ What’s left to test? After you’ve finished automated and Intelligent Guided Tests, now you can generate and share a “Remaining Testing” report, listing what’s left for manual testers. Accessibility experts can pick up exactly where you left off to catch the remaining complex issues.

A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
