Firebase review
Free tierGoogle's app backend, strongest on mobile
Firestore or the Realtime Database, plus auth, push notifications, crash reporting and analytics in one console. Offline sync on mobile is the thing it does better than anything else here.
Entry price
Free, then pay per use
Free: Spark plan is free forever: 1 GiB Firestore storage, 50K document reads and 20K writes a day, 50K auth users, 10 GB hosting.
Our Firebase verdict
Firebase costs free, then pay per use. Nobody has reviewed it here yet, so this page is about what it costs and what it does, not how well it does it.
Mobile apps that need realtime sync and offline support out of the box. There is a free tier: Spark plan is free forever: 1 GiB Firestore storage, 50K document reads and 20K writes a day, 50K auth users, 10 GB hosting..
- Who it is not for
- Firestore is a proprietary document store, so leaving Firebase means rewriting your data layer, not exporting it
- What this is based on
- Based on pricing read from Firebase's own page on 2026-08-28, and what the product says it does. No reviews yet, so no score.

Firebase does one job. These are the jobs that usually come next, and what we would look at for each.

Website Building
Compare allSomething has to sit in front of it before anybody can use it.
Chosen by what job comes next, not by any integration between them: we have not verified that these products talk to each other, so we are not going to imply it. A slot in this block is not for sale and paid placement is excluded from it outright, but some of these links do earn us a commission and the ones that do say so above.
