Why You Might Want a Firebase Alternative

1. You Do Not Own Your Data

With Firebase, your data is owned by their servers, so it won’t be possible to export your emails ✉️, accounts, passwords, and other data. The only way to retrieve your data is to directly contact Firebase’s team. That would take several days of communication back and forth before it gets done.

2. Issues With Data Migration

If you’re already using Firebase, then you might already have an idea of how much inconvenience data migration causes. Since Firebase uses JSON, data migration is complicated, unlike in a simple SQL database. If you’re managing large amounts of data, then it’s worse. You will need third-party software to perform this.

3. Querying is Limited

Firebase’s data streaming has limited query capabilities. This means that certain functions can’t be combined. You’ll have to arrange and filter data one by one then perform other actions on the client side.

4. Oriented Towards Real-time Sync

Real-time Sync is actually beneficial but can get annoying at times. It’s hard when you’re just typing a text and then the database automatically updates. If you prefer writing queries and using an event handler to update the DB, you might want to try other platforms.

5. Limited Security Rules

Firebase’s security rules are designed to be fast. The downside to this is that the rules are limited, the reason why it’s hard to build and scale a complex enterprise platform. Plus, it’s hard not to mess up the JSON files carrying the security rules, which can ruin the application.

You Might Ask

When should you not use firebase?

As we’ve mentioned above, you do not have the rights to your data in Firebase. Also, data migration, especially for big amounts, is complicated, and querying is limited. Furthermore, the DB only updates real-time, and security ???? is limited.

Which is better, Heroku or firebase?

Both are excellent platforms, although the difference is that Firebase is a BaaS and Heroku is a PaaS. If you already have a minimum viable product (MVP) with a reliable backend, you might want to go with Firebase. Heroku will be preferable if you are building a complex application as it offers flexibility. Just remember that you’ll take more time setting up with Heroku as the platform will need more technical knowledge, and you might need a dedicated resource to perform this. To conclude, Firebase offers convenience while Heroku provides variability.  

Can firebase be hacked?

There have been reports that several apps using Firebase have publicly exposed databases. This can be a security issue, especially when attackers can access, delete, modify, or exploit sensitive information, including passwords, telephone numbers, and chat messages.

What are the downsides of Firebase?

Not Open Source – You have to adapt to the language and tools Firebase is using. This means there’s also less support.

Vendor Lock-In – You’re stuck with Firebase even if you’re not happy with its performance and services.

Lack of GraphQL APIs (REST only) – You only have REST as an API. This means no flexibility for your app integration.

Is firebase better than SQL?

Firebase handles large data well, while MySQL is built to manage and simplify the more complex ones. Firebase is also marginally faster and handles data in real-time. But in terms of cost, MySQL is cheaper as it is completely free. It also offers more language support since it’s open-source.

Is MongoDB similar to Firebase?

Both services allow developers and startups to easily and quickly set up in the service and are both built with JSON-like data models. The difference is that MongoDB trumps Firebase due to MongoDB’s configurability and range of Atlas performance tiers. Both are great tools for development as well, but MongoDB is the more powerful and flexible platform.


Make no doubt about it, Firebase offers rich development features that can help ???? support and scale your application. It’s also a great platform to build on for side projects and even complete products, but with so many services with great functionality available, it’s time you check out other alternatives. You might also want to try these other services especially if you have sensitive data to process within the app. Who knows? The grass might be greener on the other side.
