Script tag

Add Monitoring to any site with a single script tag.

Paste this into your pages. It works on any site that lets you edit HTML — no framework or plugin required.

Add the script

<script src="https://accessible.so/a11y/loader.js" data-site-key="acc_rum_YOUR_SITE_KEY" async></script>

Replace acc_rum_YOUR_SITE_KEY with your site's own key — copy the snippet from your domain's Monitoring page, which already carries it — and add it to every page you want Monitoring to cover.

Attributes

See Configuration for what each attribute on the script tag does and how it interacts with your dashboard settings.

Content Security Policy

If your site sends a Content Security Policy, allow https://accessible.so under script-src, which covers both the loader and the engine bundle it downloads for sampled sessions, and https://app.accessible.so under connect-src, where config and beacon requests go. If you set data-endpoint or data-engine, or host the loader yourself, allow those origins instead. See Debugging if requests are being blocked.
