The Keupera tracker is a lightweight (under 2 KB), cookieless JavaScript snippet that streams pageviews into the [Analytics](/features/analytics) module. It populates the **Website** summary, daily traffic, top pages, referrers, devices, browsers, and geo breakdowns. ## How it works * No cookies. A `keupera_session_id` is generated in `sessionStorage` and reset when the tab closes. * Uses `navigator.sendBeacon` so the request never blocks navigation; falls back to `fetch` on older browsers. * Captures URL, path, hostname, referrer, and UTM parameters automatically. * Skips common sensitive paths (`/wp-admin`, `/wp-login`, `/admin`, `/.env`, `/.git`). ## Get your Tracking API key Go to **Account → API Keys** in your [dashboard](https://app.keupera.com). Click **Create API key** and choose the **Tracking** scope. Tracking keys are restricted — they can only send analytics events, never read or mutate other data, so it's safe to expose them in client-side HTML. Never embed a Full Access (`sk_live_...`) key in your website's HTML. Always use a **Tracking** scoped key for the pixel. ## Install on any website Paste this snippet just before `` on every page you want to track: ```html theme={null} ``` That's the whole install. The script self-initialises on `DOMContentLoaded` and fires a `pageview` event automatically. ## Platform-specific install Install the [Keupera Connector plugin](/integrations/wordpress). It injects the snippet into `wp_head` automatically when **Enable Website Analytics** is on (default). The plugin uses your Tracking key if provided, otherwise it falls back to the connected Full Access key. Install the **Keupera** plugin from the Framer marketplace and paste your Tracking key. The plugin handles the snippet injection. Add the following to your root layout (`app/layout.tsx`). Set `NEXT_PUBLIC_KEUPERA_TRACKING_KEY` in your `.env.local`. ```html theme={null} ``` Or use `next/script` — set `window.KEUPERA_API_KEY` in a `beforeInteractive` Script and load the tracker with `strategy="afterInteractive"`. Add the snippet in **Site Settings → Custom Code → Header**. The exact path varies per builder but every modern site builder supports a global `` injection field. ## Custom events (optional) After the tracker loads, `window.keupera.track(eventName, properties)` is available for custom events: ```js theme={null} window.keupera?.track("signup_clicked", { plan: "pro" }); ``` Custom events show up in the **Analytics → Events** view alongside pageviews. ## Verify the install 1. Open your live site in a new browser tab. 2. Open DevTools → **Network** and filter by `track`. You should see a `POST` to `https://sqnxgokfnvdglftrgekd.supabase.co/functions/v1/track` returning `204`. 3. In Keupera, open **Analytics → Website Summary**. New sessions appear within \~30 seconds. If you see `Keupera Analytics: API Key not found` in the console, the `window.KEUPERA_API_KEY` assignment ran after the tracker — make sure the key `
