How it works

This demo uses two feature flags defined in code control the visibility of two banners on the page. Both flags are configured to show/hide each banner 50% of the time.

Once you visit the page, you can see a variation of both/one/none of the banners. Since this example is using a stable id to identify users, you will see the same variation all the time.

To test different variations, you can use the Dev Tools at the bottom to reset the stable id and reload the page. This allows you to test different variations of the banners.

This templates also tracks analytics events in Vercel Analytics.

If you deployed your own instance of this example you can also use the Flags Explorer to test different variations by creating overrides.
