AccessiLint

Real-time WCAG 2.1 AA accessibility linting for Visual Studio 2022 — catch violations as you write, before they reach QA or a compliance audit.

What it does

AccessiLint catches accessibility violations as you write HTML, Razor, and CSHTML — before they reach QA, a client review, or a compliance audit. Violations appear directly in Visual Studio's Error List, linked to the exact WCAG 2.1 success criterion so you know what's wrong and how to fix it.

🔒 AccessiLint Pro adds one-click HTML and Word accessibility audit reports for clients and regulators. Available at novawrightstudios.com.

🏷️ Criterion-level guidance — every finding references the exact WCAG 2.1 AA success criterion

🌐 Multi-format support — .html, .cshtml, .razor, and .css files
