ComplyWCAG Documentation & Guides
Everything you need to install, configure, secure, and customize the ComplyWCAG accessibility widget on any web platform.
5-Minute Quickstart
Add the lightweight asynchronous script snippet before the closing </head> or </body> tag of your website:
<script async src="https://complywcag.com/accessibility.js?key=YOUR_PUBLIC_KEY"></script>Replace YOUR_PUBLIC_KEY with the unique key generated when registering your site in the customer dashboard.
Content Security Policy (CSP)
If your website enforces strict HTTP Content Security Policy headers, allow ComplyWCAG edge domains:
Content-Security-Policy: default-src 'self'; script-src 'self' https://complywcag.com; connect-src 'self' https://complywcag.com; style-src 'self' 'unsafe-inline' https://complywcag.com; font-src 'self' https://complywcag.com data:;Performance Benchmarks & Methodology
We continually benchmark ComplyWCAG against standard Core Web Vitals to guarantee zero perceptible performance penalty:
Gzipped Initial Loader
Main Thread Blocking
Cumulative Layout Shift (CLS)
Methodology: Measured with Google Lighthouse 11.x on simulated Moto G4 (Slow 4G / 4x CPU Throttling).
