Ask HN: Anyone else experiencing high costs using Google Firebase?

Last year I discovered Firebase and fell in love on first sight: simple to use and include in new projects.

But after a year of usage I'm shocked by the monthly costs for even simple apps. Putting and storing data in Firebase is cheap, but displaying / transferring data is a huge pain point in terms of costs right now.

Example: on Firebase Blaze plan (pay as you go) I'm paying right now $50 for 60GB of data transfers.

I've developed a simple backend web app to update entries. Loading a complete list of entries from Firebase costs a lot money, because it'll transfer maybe a megabyte of JSON. So I had to think about how to structure my data in terms of costs first. This is something I'd never experienced before.

Has anyone else similar experiences and possible tips?
