10 Best Open Source Firebase Alternatives

Google’s Firebase is an app development platform that’s used in building, improving, and growing mobile apps. The platform offers a collection of powerful tools that help you develop, handle, and enhance your apps based on demand.

For developers, Firebase helps to solve issues such as building apps faster, releasing and monitoring apps with confidence, and engaging the users of the app. Not only that, but developers also get access to services they’d normally have to develop on their own.

Developers are also able to shift their focus more on delivering robust app experiences for users, compared to the technical issues of the application.

Some of the standout features you’ll find in Firebase include file storage, hosting, notifications, real-time databases, push messages, authentication, and analytics. The service is cloud-hosted, meaning developers can carry out on-demand scaling without hassles.

Unlike Firebase, which works only with NoSQL databases, Couchbase can scale easily to be more hardware efficient compared to other NoSQL databases. Thus, the database adds more RAM, CPU capacity, and disk space to grow horizontally and share the load.

You can use Couchbase for free and provide outstanding performance in the cloud, on-premises, in a container, or edge service at scale.

6. NativeScript

NativeScript is another open-source platform that you can use to create native mobile apps with one codebase using CSS and JavaScript libraries that you already have.

The framework can develop native apps with Angular, TypeScript, or JavaScript and is based on write once and run everywhere logic.

The native apps you develop use the richness of the mobile platform and offer the performance you need for mobile devices. NativeScript uses native APIs and controls to render, allowing you to create more sophisticated apps compared to using a hybrid approach.

In hybrid apps, you don’t get the same performance or flexibility because they’re hosted on a different framework and don’t interact directly with low-level mobile APIs.

You can also build truly native apps easily using the Firebase Plugin by Master Verbruggen, to bring the real-time connectivity and speed of Firebase to NativeScript.

NativeScript is a suite of professional services and products which include troubleshooting reports, performance analysis, in-person training, performance analysis, and coding assistance.

7. RxDB

Reactive Database or RxDB is a real-time NoSQL database for JavaScript apps such as progressive web apps, electron apps, PWAs, hybrid apps, and websites. Reactive means that you get to query the current state while subscribing to all state changes like the result of a single field of a document or query.

For user interface-based real-time apps, the RxDB platform makes it easy to develop and also has great performance benefits.

You can replicate data between your server and clients because RxDB offers modules for real-time replication with any endpoints that are compliant with CouchDB and with GraphQL endpoints.

Among the core features of RxDB include real-time queries, replication, schema, encryption, multi-window tab support, and a key compression module.

The platform is open source, unlike Firebase, whose platform doesn’t offer all services for free to start. Plus, you get real-time queries, unlike Firebase, whose queries are slow, and you’re not locked into a particular vendor or Google Cloud framework.

8. Flutter

Flutter is another open-source app development framework but it’s part of the Google family of software just like Firebase. The framework is used to build native-looking mobile apps from a single codebase and was created about six years ago.

Flutter is popular for several reasons including the ability to develop apps quickly and achieve native visual consistency and performance on different platforms.

Unlike Firebase, the Flutter platform is built on widgets, including fonts, scrolling, and styles. You can also build apps with Flutter, but it won’t work well on text-rich sites like blogs.

The platform has a growing community that is among one of the best and most helpful and offers resources and documentation of the highest quality.

As Google’s user interface toolkit, you can use it to build beautiful, natively compiled web, mobile, and embedded apps from one codebase.

The platform is a software development kit that also offers tools, libraries, and documentation that help you build cross-platform apps. This way, you can build native interfaces in minutes, ship features with a focus on native end-user experiences, and delight your users with rich features.

The app development framework is fully free unlike Firebase, whose features aren’t all free to start with, and can be used on all major operating systems including Google Fuschia.

9. LoopBack

LoopBack is an open source Node.js framework that’s highly extensible and helps developers compose scalable APIs quickly. The platform runs on top of the TypeScript framework that’s based on the Express web framework.

This way, you can create dynamic end-to-end REST APIs quickly and connect to backend systems like REST or SOAP databases and services.

You can also create models based on schema, or if you don’t, you can define models and build relationships between them.

The platform includes a new core to deliver great flexibility and extensibility. It also allows you to solve business issues such as expanding products and services to reach audiences of developers who consume the APIs.

LoopBack eases the creation of a REST API with minimal coding while offering a consistent way of designing and implementing APIs including the ORM, REST layer, and models.

The advantage LoopBack has over Firebase is that it’s open source, connects to legacy systems, and works with multiple databases, not just NoSQL like Firebase.

For developers, LoopBack helps you define your endpoints and schemas and write endpoints in modern JavaScript. You can also use defined endpoints and schemas as the source of truth without having to generate code.

Teams can also use LoopBack to review changes to endpoints without having to dig through JavaScript and maintain consistency through automation of endpoint and schema validation.

For your platform, you can use LoopBack to start creating your own platform or framework. You can also use it to build standard libraries of reusable components and use connectors to integrate with web services, databases, and other platforms.

10. SashiDo

SashiDo is a platform that helps developers build APIs quickly. The open source service can help you build global serverless apps using scalable GraphQL API and NodeJS Rest, compared to Firebase, which only uses the NoSQL database.

With SashiDo, you can also build easy-to-use CMS, built-in CDN, CRUD, user management, object and file storage, system emails, relations, push notifications, and cloud functions among others.

You can automatically scale your app based on its need so you won’t have to worry whether or not the app can handle the traffic. SashiDo also eliminates limitations of monthly requests for the service or requests per second, meaning your app is scalable to your needs.

You can also create web and mobile apps on any platform using any SDK you want, and deploy your custom business logic on your server the way you want it to be.

In addition, SashiDo allows you to integrate third-party tools using WebHooks, but you also get countless opportunities to expand your apps’ functionalities.

The open source platform is free to use, including all its features, unlike Firebase, whose features aren’t all free to start. Plus, you’re not locked into one framework and you can enhance your apps however you want to engage with your customers.

Wrapping Up

These open-source alternatives to Firebase are all completely free to use. Before you pick any of them, consider software architecture, support, maintenance, and integration capabilities.

Think about the business-level compatibility that the app will bring, security, your audience, the features proprietary to the platform, and your return on investment (ROI). This way, you can pick an app development framework that’s unique and fits your business needs.

We recommend AWS Amplify because it’s not just open source but stable, feature-rich, and you’re not locked into a specific vendor.
