A little harsh review
Now, some might strongly disagree with me on what I am about to say, just keep in mind this is my opinion: First off, firebase is amazing for any new or experienced developer that wants to create a web application but doesn't like back-end or needs a trusted ( more on that later ) hosting for it. The features it offers are 2 types of databases, a storage solution, authentication, ads, analytics and functions. All of them run fine and are just as promised, the problem appears when you start going over the free limit. While not being very expensive, sometimes renting a VPS, setting up Appwrite.io and using that is cheaper, as firebase has Google Cloud prices, which are not the most friendly ones. Now, about privacy: technically, when you store a users data with firebase you don't actually own it ( by my understanding of the service terms ), meaning your users data is not private from third parties, leaving google with all of your data at their disposal. tl;dr : Why 3 stars? Well, I like my users data to be private and be shared only with my and theirs consent. Also, it is a bit pricey compared to the self-hosted alternative. Is it amazing? 100% yes! Would I used it in production? If the data is shared by default, no.
