Set up in a minute

The proxy is optional. It's also how you catch the visitors other tools miss.

  1. Step 1
    Add the script
    Paste it into your <head>. Pageviews and errors start coming in.
    index.html
    <script
  defer
  data-website-id="your-site-id"
  src="https://usedatasense.com/js/script.js"
></script>
  2. Step 2
    Serve it from your domain
    Two rewrites, and ad blockers see a first-party request.
    next.config.ts
    { source: "/_ds/js/script.js", destination: "https://usedatasense.com/js/script.js" }
{ source: "/_ds/api/e", destination: "https://usedatasense.com/api/e" }
  3. Step 3
    Watch, track, export
    Visitors show up in about a second. Goals are one line of code.
    anywhere in your app
    window.datasense("signup", { plan: "pro" })

<button data-ds-goal="checkout">Buy</button>

Proxy

A proxy ad blockers don't stop

Requests come from your own domain, so uBlock, Brave and private windows still count.

  • Goals & custom eventsOne function call or a data attribute.
  • Sources & UTMReferrers and campaigns, attributed per session.
  • Cookieless by designDaily-rotating hashes. No raw IPs stored.
  • FeatherweightUnder 3 KB. Never blocks render.

Count the visitors other tools can't see

Ad blockers drop requests to known analytics domains. Serve the script from your own domain and there's nothing to block.

  • Works with uBlock Origin, Brave, Safari private and Firefox strict mode
  • Pick your own path, so filter lists can't guess it
  • Recipes for Next.js, Vercel, Netlify, Cloudflare and Nginx
Pick your stack
Your dashboard fills in your site ID.
next.config.ts
// next.config.ts
import type { NextConfig } from "next"

const nextConfig: NextConfig = {
  async rewrites() {
    return [
      { source: "/_ds/js/script.js", destination: "https://usedatasense.com/js/script.js" },
      { source: "/_ds/api/e", destination: "https://usedatasense.com/api/e" },
    ]
  },
}

export default nextConfig
Then load the script from your own domain
<script
  defer
  data-website-id="your-site-id"
  src="/_ds/js/script.js"
></script>
