Supabase: The Best Open-Source Firebase Alternative (And So Underrated)

At Blanche Agency, we're always on the lookout for powerful, efficient tools that allow us to build scalable and secure applications quickly. One of our go-to platforms, which we believe is highly underrated, is Supabase. Often described as an open-source alternative to Firebase, Supabase offers many of the same features—real-time databases, authentication, and storage—but with the added advantages of being open-source and based on PostgreSQL.

In this article, we’ll dive into why Supabase is an exceptional platform, why we prefer it over Firebase for many of our projects, and why it deserves far more recognition in the development community.

Why Supabase Is the Ideal Firebase Alternative

Firebase has been a popular choice for developers who need a Backend-as-a-Service (BaaS) to quickly build and scale applications. However, Supabase has rapidly emerged as a compelling alternative, offering many of the same features while providing some key advantages that make it our platform of choice.

Here’s why Supabase stands out:

1. Open-Source and Built on PostgreSQL

Unlike Firebase, which is proprietary and relies on its NoSQL database (Firestore), Supabase is open-source and built on PostgreSQL. PostgreSQL is an industry-standard relational database known for its robustness, scalability, and support for complex queries.

Advantages of PostgreSQL:

• SQL: For developers who prefer working with SQL, Supabase offers the full power of PostgreSQL. This allows for complex queries, joins, and other advanced database features that Firestore simply can't handle in the same way.
• Flexibility: Supabase’s relational model is often a better fit for applications that require complex relationships between data entities—something that can be cumbersome in a NoSQL database like Firestore.
• Open-source: Supabase’s open-source nature means you can host it yourself, contribute to its development, or modify it to suit your needs. This offers far more flexibility and transparency compared to Firebase’s closed ecosystem.

2. Real-Time Capabilities

Supabase is built with real-time features baked in, just like Firebase. Every change to the database can trigger a real-time event, meaning you can build applications that update instantly without constantly refreshing the data.

For example, we’ve used Supabase’s real-time functionality in several projects to create live chat applications, collaborative tools, and dashboards where users see updates as soon as they happen. This is achieved using Postgres's built-in replication features, allowing for efficient real-time updates without any third-party solutions.

3. Authentication and Authorization Made Simple

One of Supabase's standout features is its auth system, which is fully integrated with the PostgreSQL database. Just like Firebase, Supabase offers an easy-to-use authentication service with support for OAuth providers like Google, GitHub, Facebook, and Twitter, as well as email/password and magic link authentication.

Key Benefits:

• Customizable Authorization Rules: Supabase lets you set row-level security (RLS) policies, making it extremely flexible for creating custom user permissions. This is a huge plus compared to Firebase’s somewhat limited rule system.
• User-Friendly Interface: The Supabase dashboard makes managing users and authentication flows straightforward, allowing developers to set up auth systems without dealing with too much configuration.

4. Storage for Files and Media

Supabase includes a storage service that is perfect for handling file uploads, which Firebase also offers through its Cloud Storage service. What we like about Supabase’s storage is that it’s also integrated with the database and real-time capabilities, making it easy to manage media assets like images, videos, and documents alongside your app’s data.

Supabase storage uses S3-compatible object storage, meaning it’s both scalable and secure. You can also set bucket policies to control access to files, making it simple to manage public and private assets within your application.

5. Serverless Functions

In addition to its core services, Supabase is starting to roll out Edge Functions—a serverless function layer built on Deno. This means you can write custom backend logic that runs on-demand and scales automatically, all within the same platform. It’s similar to Firebase’s Cloud Functions, but the fact that it’s built on an open-source stack gives you more flexibility and control.

6. Developer-Friendly Pricing

Supabase’s pricing is highly competitive, especially for small to medium-sized projects. It offers a free tier with generous limits that allow you to prototype and build fully functional apps without upfront costs. As your application grows, Supabase’s pricing scales based on your usage, making it cost-effective compared to Firebase, which can become expensive as your app scales.

7. Ease of Setup and Developer Experience

One of the things we love about Supabase at Blanche Agency is how easy it is to set up. In just a few clicks, you can have a fully functional backend with a real-time database, auth, and storage ready to go. The development experience is smooth, with extensive documentation, code examples, and a helpful community that makes it easy to get started and resolve any issues.

Supabase also integrates seamlessly with popular frontend frameworks like React, Next.js, and Vue, making it a great match for our tech stack. We’ve found that its APIs are well-documented and intuitive, allowing our developers to focus more on building features rather than managing infrastructure.

Why Supabase Deserves More Recognition

Despite offering so many powerful features, Supabase still flies under the radar compared to Firebase. But as developers, we find that its open-source nature, robust SQL foundation, and developer-friendly features make it an incredibly versatile tool for modern web and mobile app development. It combines the best of both worlds: the speed and ease of use of Firebase with the power and flexibility of PostgreSQL.

At Blanche Agency, we’ve successfully used Supabase for projects ranging from SaaS platforms to real-time applications, and we couldn’t be happier with its performance. We encourage more developers to explore what Supabase can do—it’s a truly underrated tool that delivers enterprise-grade features without the restrictions of proprietary platforms.

Final Thoughts

If you're looking for a powerful, open-source backend solution, Supabase is the clear choice. Its real-time database, flexible authentication, integrated storage, and open-source model make it a top contender as a Firebase alternative. At Blanche Agency, we continue to integrate Supabase into our projects because it combines the scalability of a modern BaaS with the freedom that developers crave.
