WAVE Web Accessibility Evaluation Tools

Overview

WAVE is a suite of evaluation tools designed to help web developers, designers, and content authors identify and fix accessibility errors and WCAG violations in web content. Unlike automated checkers that flag every possible issue, WAVE focuses on problems that genuinely impact users with disabilities and facilitates manual review rather than relying solely on automated detection.

WAVE provides three distinct approaches: an online tool for quick testing, browser extensions for Chrome, Firefox, and Edge that let you test password-protected or dynamic pages directly in your browser, and a subscription API for large-scale testing across multiple pages and continuous integration workflows.

Key Benefits

• Test accessibility directly in your browser without uploading pages or entering URLs manually.
• Access the Accessibility IMpact (AIM) assessment report, which scores your site based on end-user impact and includes expert manual test results.
• Integrate the stand-alone API and testing engine into your infrastructure to test intranet, non-public, and secure pages.
• Identify WCAG errors and accessibility issues that actually matter to users rather than every automated flag.
• Monitor and test intranet pages, locally stored content, and highly dynamic applications without restriction.

How It Works

To test a public webpage, you enter the URL into the online WAVE tool. For browser-based testing, you install a WAVE extension in Chrome, Firefox, or Edge, then run it directly on any page you visit. For enterprise-scale testing, you integrate the stand-alone API and testing engine into your infrastructure, either for one-time assessments or as part of continuous integration pipelines.

Use Cases

• Web developers building internal applications can use the stand-alone testing engine to check intranet pages and non-public environments without uploading sensitive content.
• Accessibility auditors and consultants rely on WAVE to generate AIM reports with manual test results, helping them document compliance and advise clients on fixes.
• Content teams managing dynamic websites use the browser extensions to test pages as they appear to end users, catching issues that static HTML analysis misses.
• QA teams integrate WAVE into continuous integration workflows to automatically flag accessibility regressions as code is deployed.
• Educational institutions use WAVE to teach students about web accessibility standards and hands-on evaluation techniques.

Why Choose This Product

WAVE is best suited for organizations that prioritize real user impact over checklist compliance and want flexible testing options ranging from quick browser checks to enterprise-scale automation. The product was created by Utah State University's WebAIM program, a widely recognized authority in accessibility education and evaluation.
