Install Dupes in a minute

Dupes is a single lightweight script that tracks your visitors — plus a server-side detector for AI crawlers. Works with any stack, and every site can run cookieless if you'd rather not ask for consent.

Add your site

In the dashboard, click Add site, enter a name and your domain. You'll get a website ID that looks like dps_….

Drop in the script

Paste this before the closing </head> on every page, using your own website ID and domain:

Watch data flow in

Deploy and open your dashboard. Pageviews, channels, campaigns, pages, devices and geography appear within seconds — plus any AI crawler visits.

<script>window.dupes=window.dupes||function(){(window.dupes.q=window.dupes.q||[]).push(arguments)}</script>
<script
  src="https://usedupes.com/js/script.js"
  data-dupes-id="dps_your_site_id"
  data-dupes-domain="yourdomain.com"
  defer
></script>

Script options

Only data-dupes-id is required.

Attribute	What it does
data-dupes-id	Your website ID. Required.
data-dupes-domain	Domain shown in the dashboard.
data-dupes-hostnames	Comma-separated allowlist, e.g. example.com,*.example.com. Blocks staging clones and mirrored copies from polluting your numbers. Omit to allow every hostname.
data-dupes-localhost	Set "true" to track localhost while developing.
data-dupes-iframe	Set "true" to track when embedded in an iframe. Off by default — embedded copies usually aren’t your traffic.
data-dupes-api	Custom collect endpoint, if you proxy it.

The script skips automated browsers (headless Chrome, Selenium, Puppeteer, Playwright) so scrapers don't inflate your visitor count, and captures the browser's timezone and language — which stay accurate behind VPNs and proxies, unlike IP geolocation. Paid clicks are attributed from gclid, fbclidand friends, so ad traffic doesn't land in Direct.
