Checking if a Movie has a Post or Mid Credit Scene

This is a simple no-frills web-app that tells you if a movie has credits scenes or not.

I saw it pop up in the !kagismallweb@lemmy.world. The link goes to a blog post about how they made it, but here's the link directly to the thing:

Seems super useful, and the opening paragraph about how annoying it is searching for that info resonates. It's kinda rough tho, UI could probably use another pass.

But maybe there are already better existing solutions you all can suggest?
