Add analytics to HTML without cookies

One script tag, about 1.2 KB compressed, with no visitor cookies and no build step.

Where the tag goes

Paste it just before </head> in every page you want counted.

<script async src="https://simplytics.dev/track.js" data-key="YOUR_SITE_KEY"></script>

Where your key comes from

Swap YOUR_SITE_KEY for your own key, which is on your dashboard beside each site. One key covers the whole site.

Is the key a secret?

No. It is a public identifier that ships in the tag on every page you track. But a tag carrying YOUR_SITE_KEY reports nothing at all, so swap it before you deploy.

Check that it is working

  1. Deploy, then open any page of your site in a normal browser window.
  2. Open your dashboard. The visit appears within seconds.
Nothing after 60 seconds?
  • Your own ad blocker. Most silently block any script with "analytics" in the path. Try a private window with the blocker off, or open the site on your phone.
  • A subdomain. www.example.com and example.com are treated as the same site, but blog.example.com is not — add it as its own site.
  • Not deployed yet. Views from localhost or a preview URL are refused: the hostname has to match a site on this account.
  • A Content-Security-Policy. If your site sends one, add https://simplytics.dev to both script-src and connect-src: the tag loads from there and reports back to it.
  • Your own browser is opted out. Brave and DuckDuckGo send Global Privacy Control by default, so the tag sends nothing and your visit looks like a broken install. Test in a browser that does not send it, or see the opt-out page.

Single-page navigation

Client-side navigations are counted automatically. Do not fire anything yourself; that double-counts.

Which navigations count, and which do not

Client-side navigations are counted automatically: the tag patches history.pushState, history.replaceState and popstate, and counts again whenever the path changes. Do not fire anything yourself; that double-counts. Changes to only the query string or the # fragment are ignored, so a router that navigates by # alone is not counted automatically.
