How to know if a website uses the AppLovin (Axon) Pixel

Open the page's source (Ctrl+U, or Cmd+Option+U on a Mac) and search for axon, AXON_EVENT_KEY, or s.axon.ai. If the pixel is installed you'll find the account's event key set in AXON_EVENT_KEY. Don't want to dig through code? Paste the URL above.

1

Read the page source

Right-click the page, choose “View page source” or press Ctrl+U, and search for axon or AXON_EVENT_KEY. A match means the pixel is on that page.

2

Check the Network tab

Open DevTools (F12), go to Network, filter for axon, then reload. A request to s.axon.ai/pixel.js confirms the pixel is loading, even when it's added through a tag manager.

3

Look for the _axwrt cookie

The Axon Pixel sets a first-party cookie named _axwrt to identify visitors. Finding it under Application, Cookies in DevTools is another sign the pixel is live.

4

Paste it above

The fastest option when you just want a yes or no and the event key. No extension, no DevTools, works on any URL.

questions

the AppLovin (Axon) Pixel, answered.

Yes. AppLovin runs its self-serve web advertising under the Axon brand, so the web pixel is officially the Axon Pixel. People still call it the AppLovin pixel. They're the same snippet that loads s.axon.ai/pixel.js.
It's the identifier that ties pixel events to an AppLovin/Axon account. The install snippet sets it with var AXON_EVENT_KEY="..." and the pixel sends it with every event. You can find your own key in the AppLovin dashboard under Account, General, Keys.
Some sites load the pixel through Google Tag Manager or a consent platform, or only after a visitor accepts cookies, so it isn't in the raw HTML we read. The Network tab catches those cases: filter for s.axon.ai and reload.
Yes. The snippet sits in public page source, so anyone can see whether the pixel is present and what event key it uses. You can't see their campaigns, audiences, or conversion data, only that the pixel is there.
Yes. AppLovin offers a Shopify app and a Google Tag Manager path in addition to the native JavaScript snippet. However it's installed, the page ends up loading the same Axon pixel script, which is what this checker looks for.
The check is free and reads only public page source. We don't save the URLs you enter.
