Accessibility audits, anywhere

A zero-dependency WCAG engine that runs in browsers, headless browsers, and server-side DOMs — in under 100ms.

Why @accesslint/core

Median audit completes in 52ms across 5,000 real-world sites — significantly faster than alternatives.

93 rules covering images, forms, ARIA, landmarks, color contrast, keyboard access, and more — all mapped to WCAG 2.1.

Every rule ships with guidance and prompts for AI-powered remediation. Built for the next generation of developer tools.

npm install @accesslint/core

import { runAudit } from "@accesslint/core";

const result = runAudit(document);
console.log(result.violations);
