Using Firebase in production

Firebase team member here.

We have a lot of large customers who use Firebase in production.

The main metric to be aware of are the concurrent users. Basically, how many devices are connected to the app at the same time.

The free plan covers you up until 100 concurrent users. The $5 spark plan gives you a custom domain. After that you have unlimited concurrent uses but there's different metrics like data storage and bandwidth to be aware of.

For your use case I believe you would be just fine on the free plan.

Also, if you're building and Ionic app, check out our AngularFire library. It will save you a lot of time and make developing your app a lot more enjoyable.

@David East All Others,

Coming back here after around 5 years after my initial question . Over the time has firebase had bought in some major upgrade's to use it as a single platform for all your backend needs . It has a solution for all your problems and with NOSQL DB, you will be able to ship your product . I was able to ship a PWA on react with using Firestore for an organization in 3 weeks time . The average server charges are also considerably low for any other alternate solution you would choose.
