Yeah it's a good service for hosting images and video. I'm actually quite impressed with the Nostr integration.

If you have an account, a few Nostr clients allow you to make a note in the client and it will drop the file right into your nostr.build account and then attach it to your note. No need to upload a file first at the nostr.build website, get a link and then put that link in the client. Saves some time.
