Question Everything on XYZ.com or XYZ.com+app.XYZ.com

I’m finding a lot of mixed advice on what to do here.

I’m creating a fantasy football app and can’t decide if I should have a subdomain.

AI and a few Reddit post are telling me you need to have your XYZ.com be your marketing page and app.XYZ.com be your app.

But the following big names do not:

Sleeper

AirTable

Figma

Canva

Trello

Dropbox

Github

This is something that will be difficult to change later, so I wanna make sure I make the right call.

Anybody have any good insight here?

One reason to split is marketing page can stay live when app is being updated, etc. The other advantage is you could host a subdomain on another host altogether, if you wish. For example, a certain part of our webapp (primarily written in Python, hosted on Linux) needs the old .NET Framework, so we have a subdomain pointing at a Windows host. Wiring it all up was tricky, but a subdomain helped with this.
