cypress-axe is the direct starting point for adding axe-core accessibility checks to Cypress tests. For richer in-runner feedback or reports, consider wick-a11y or cypress-a11y-report; for a different checking engine, consider cypress-accessibility-checker, which integrates IBM Equal Access. These are community plugins, so check their current Cypress compatibility and maintenance before installing. Automated scans find useful classes of problems, but they cannot prove that an application is accessible.

Cypress labels these as community plugins and says it does not review community-owned plugins. Directory versions and update dates are a snapshot, not a substitute for checking a package’s current releases, issue activity, license and contents. See the Cypress plugin directory before choosing.
What to check before adding a package
- Confirm that the package’s published Cypress range includes the version your project uses.
- Review its latest release, maintenance activity, license and installation instructions in the package’s own repository or registry listing.
- Decide whether your team needs raw axe findings, runner highlighting, a report, or an alternate engine.
- Plan which UI states tests will scan; a plugin only checks when and where your tests invoke it.
How to add axe checks with cypress-axe
Cypress documents cypress-axe as an integration that adds axe-core checks to Cypress tests. Install the package version compatible with your project, register its commands in your Cypress support file, then call cy.checkA11y() after the page or component state you want to inspect is ready. Cypress’s setup and configuration details are in its accessibility testing guide.
- Install: add
cypress-axeas a development dependency using the package manager and version appropriate for your project. Check package instructions and compatibility before pinning a version. - Register commands: import the package’s Cypress commands from the support file loaded by your tests, following the setup instructions for the installed version.
- Visit or mount the interface: wait until the relevant page or component has rendered and any state-specific controls are present.
- Run a scan: invoke
cy.checkA11y()at that point in the test. Configure scope, rule selection and failure behavior when appropriate; consult Cypress documentation for supported options. - Repeat for meaningful states: add scans after actions that expose important content, such as opening a menu, showing validation errors or displaying a modal.
The exact install command and support-file path can vary with the package version and Cypress project configuration. Use the package’s current installation directions rather than copying an outdated path or assuming a particular project layout.

Choose scan points around user-visible states
A scan is a snapshot of the current rendered state, not a test of every possible interaction. Include states with distinct accessibility implications: for example, a closed and open navigation menu, an empty and invalid form, or a modal before and after dismissal. Avoid repeating scans on identical states without a reason.
Scope rules and page regions deliberately
Cypress says checks can be configured for particular WCAG success criteria and related rules, and scans can be limited by page scope or rule scope. Narrowing scope can help focus a test, but it can also hide findings outside that scope. Record why a rule or region is excluded and retain broader checks where they are useful.

What each option adds beyond a basic scan
cypress-axe: direct control over axe scans
Use it when test authors should choose the point in a flow to scan and want to configure rule scope or whether findings fail a test. Cypress describes axe-core as able to catch issues such as poor color contrast, missing labels and missing image alt text, while emphasizing that those findings are not a complete accessibility evaluation.
wick-a11y: more visible runner feedback
Wick-a11y builds on cypress-axe. In a November 7, 2024 Cypress article, its creator described raw findings as a usability problem; the article attributes visual highlighting, HTML reports with screenshots and voice feedback to the plugin. These are creator and vendor descriptions, not an independent performance comparison. The reviewed directory excerpt does not establish a current version or Cypress compatibility range, so verify both before adopting it. Cypress’s article on open-source accessibility plugins

How automated scans fit into accessibility testing
Cypress’s guidance is direct: “While automated scans do a good job at detecting violations of a known list of rules, no automated scan can prove that the interface is fully accessible and works well for users with disabilities.” Treat a clean scan as evidence about the rules it checked in that state, not as a conformance guarantee. Cypress Accessibility Testing
Pair scans with explicit application tests and human evaluation. Cypress documents using native key events to check keyboard navigation, asserting image alt text and accessible names, and using accessible locators. A locator alone is not proof: assert the expected behavior or implementation, such as whether keyboard interaction reaches and activates the right control. Include manual evaluation of the experience, including keyboard and screen-reader-relevant behavior.

Runtime, reliability and CI considerations
Each scan evaluates DOM elements against applicable rules and takes time. Cypress cautions that many repeated scans across hundreds or thousands of application states can materially increase pipeline runtime. Choose states that add distinct coverage, avoid redundant scans, and consider component tests or narrower rule and page scopes where they fit. Do not optimize runtime by omitting important interactive states from the user journey.
Keep the test failure policy aligned with the purpose of the suite. If findings should block changes, configure checks to fail the test and ensure the CI output makes the violations actionable. If a team uses a reporting-focused extension, confirm how its reports are produced and retained in the current version; the directory metadata alone does not establish those details.
Common selection and setup problems
- Plugin does not work with the installed Cypress release: compare the package’s published compatibility range with your project’s Cypress version, then choose a supported release or a different plugin. Do not extrapolate a directory range that ends at an earlier major version.
- The scan reports no issues, but a flow still behaves poorly: automated rules cannot judge every interaction. Add assertions for the expected keyboard, naming and state behavior, then evaluate the experience manually.
- Checks slow the CI pipeline: remove duplicate scans of unchanged states, keep scans at meaningful transitions and consider component tests or narrower scopes without dropping important flows.
- Findings are difficult for the team to interpret: retain cypress-axe for direct findings or evaluate a presentation-oriented extension such as wick-a11y or cypress-a11y-report. Verify current support and report behavior before adopting either.
- Different engines produce different findings: axe-core and IBM Equal Access are different integrations. Review each engine’s documentation and decide which rule coverage and workflow meet your needs instead of assuming identical output.
ScreenshotNeo as a separate screenshot tool
ScreenshotNeo is a website screenshot API and MCP server, not a Cypress accessibility-testing plugin; it does not replace the Cypress checks above. For developers who also need website screenshots, it is an alternative to try first: it removes cookie banners, popups and chat widgets before capture, bills only clean shots, and provides an MCP server for AI agents. Details: ScreenshotNeo.
For accessibility work, use the Cypress testing approach described above; a screenshot alone does not establish accessibility. ScreenshotNeo may be useful separately when you need programmatic page images or PDFs.

Does a passing Cypress accessibility scan mean my site is accessible?
No. It indicates that the scan did not report violations among the rules it ran on the tested state; it is not proof of full accessibility.
Is cypress-a11y-report compatible with Cypress 15?
The Cypress directory snapshot reviewed October 3, 2026 listed it for Cypress ^10 through ^13, so compatibility with Cypress 15 is not established there. Check the package’s current compatibility information.
