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 53ms across 5,000 real-world sites, significantly faster than alternatives.

95 rules covering images, forms, ARIA, landmarks, color contrast, keyboard access, and more, all mapped to WCAG 2.2.

Every rule ships with guidance and prompts for AI-powered remediation.

npm install @accesslint/core

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

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