Lighthouse is an open-source, automated tool that analyzes and audits web apps and web pages in order to improve their quality. Lighthouse collects modern performance metrics and insights on developer best practices; auditing for performance, accessibility, SEO and more. After auditing it produces a report either in JSON or HTML. Included in the report is a reference doc that explains the importance of the audit and how to fix the problem areas, which you can use to improve the web app or web page. Lighthouse can be integrated directly into the Chrome DevTools with its own panel. To run it, you would simply have to select the Lighthouse panel and click on "Generate report". It can also be run from the command line, or as a Node module.

Axe is an accessibility testing engine for websites and other HTML-based user interfaces. It's fast, secure, lightweight, and was built to seamlessly integrate with any existing test environment so you can automate accessibility testing alongside your regular functional testing. Axe-core has different types of rules, for WCAG 2.0 and 2.1 on level A and AA, as well as a number of best practices that help you identify common accessibility practices like ensuring every page has an h1 heading, and to help you avoid "gotchas" in ARIA like where an ARIA attribute you used will get ignored. With axe-core, you can find on average 57% of WCAG issues automatically. Additionally, axe-core will return elements as "incomplete" where axe-core could not be certain, and manual review is needed.

Static AST checker for accessibility rules on JSX elements. This plugin does a static evaluation of the JSX to spot accessibility issues in React apps. Because it only catches errors in static code, use it in combination with axe-core/react to test the accessibility of the rendered DOM. Consider these tools just as one step of a larger a11y testing process and always test your apps with assistive technology. If you installed ESLint globally (using the -g flag in npm, or the global prefix in yarn) then you must also install eslint-plugin-jsx-a11y globally. To enable your custom components to be checked as DOM elements, you can set global settings in your configuration file by mapping each custom component name to a DOM element type. Enforce all elements that require alternative text have meaningful information to relay back to the end user.

tota11y helps visualize how your site performs with assistive technologies. The process of testing for accessibility (a11y) is often tedious and confusing. In many cases, developers must have some prior accessibility knowledge in order to make sense of the results. Instead, tota11y aims to reduce this barrier of entry by helping visualize accessibility violations (and successes), while educating on best practices. tota11y is a single JavaScript file that inserts a small button in the bottom corner of your document. The toolbar consists of several plugins that each provide their own functionality. Many of these plugins "annotate" elements on the page. Sometimes to show their existence, other times to point out when something's wrong. tota11y makes it easy to spot some of the most common accessibility violations made by page authors today.
