It's a joke and a real product - they have a real landing page too.

https://fibery.io

vs

https://fibery.io/anxiety

They have 4:

https://fibery.io/build

https://fibery.io/freedom

https://fibery.io/connect

https://fibery.io/anxiety

It appears to round-robin on page load of https://fibery.io/

Mobile browser hiding the URL makes this approach work almost too well.

I think this will backfire if it gets more traffic than the real page.

The joke one is so much more concise and just better. I know what the product is about instantly.

Someone is really committed to this.
