I’m considering using Realm Sync for a new project, but I’m trying to understand if I’m misunderstanding the pricing.
If I understand the pricing (and that’s a big “if”), Firestore seems a lot more economical. Unless I’m missing something, the free tier seems far better on Firestore as well as the pricing after that (seems like it’s half the cost of realm sync).
https://cloud.google.com/firestore/pricingFirebase Prices for Requests
Reads $0.036 per 100,000 documents
Writes $0.108 per 100,000 documents
Delete $0.012 per 100,000 documentsData Storage = $0.108 / GB per monthLet’s say that averages out to around 0.072 per 100,000 requests (excluding deletes)
Realm Sync Pricing
https://docs.mongodb.com/realm/billing/ $0.2 per 100,000 requests (effectively double if I’m reading it correctly).
Plus a sync cost of 0.00000008 / min.
Plus data transfer = $0.12 / GB
Seems like Realm double/triple charges for syncs (since it charges for the requests, sync time, and data transfer), and the cost per request being more than double than Firestore
I guess the biggest difference is with Firebase you’re going to be paying a monthly fee for storage but I think the requests will be the most costly aspect of most apps (I could be wrong). Beyond that, Firestore isn’t truly off-line first.
Check out the examples for example mobile product cost:

The costs per request seem to be the big differentiator. The free tier seems to be more generous with Firebase as well. Am I missing something or is Realm significantly more costly when compared with Firestore?
