Is there a page where you can find out on which portal you can watch movies?

I would like to know, if there's a page where you can search for a movie and this one tells you that you can watch it on certain portals like Netflix, Amazon Prime etc.

So how does such a comparison for streaming portals

Most of the time, I search Google for the movie and add "Stream German" at the end. Then many websites show where you can watch the movie.

I think I found a page. Just entered your search suggestion and landed on werstreamt.es. Believe, that's what I'm looking for.

There are, for example, the following pages:

https://www.werstreamt.es/...treamt.es/
http://www.vodster.de/
https://www.justwatch.com/de
