Supabase vs Firebase: Which Is the Better Choice for Your Next Project?

As we move deeper into 2026, the question of which backend as a service (BaaS) to choose is more relevant than ever for indie hackers and solo founders. Supabase and Firebase both offer powerful features, but they cater to different needs and philosophies. If you're trying to decide between them, you're not alone. Many builders find themselves torn between these two platforms, especially with the rapid evolution of tools and features.

Overview of Supabase and Firebase

Before diving into the comparison, let’s clarify what each platform brings to the table.

Supabase is an open-source alternative to Firebase that aims to provide an easy way to set up a backend. It uses PostgreSQL as its database, which is a solid choice for those looking for relational database capabilities.

Firebase, on the other hand, is a Google-backed platform that has been around for years. It offers a comprehensive suite of tools for building and scaling applications, including real-time databases, authentication, and analytics.

Feature Comparison

| Feature | Supabase | Firebase | |----------------------|---------------------------------------|-----------------------------------| | Database Type | PostgreSQL (relational) | Firestore (NoSQL) | | Real-time Capabilities| Yes | Yes | | Authentication | Built-in support (OAuth, email, etc.)| Comprehensive auth options | | Pricing | Free tier + $25/mo for Pro | Free tier + $25/mo for Blaze | | Hosting | Managed hosting available | Hosting with Firebase Functions | | Analytics | Basic support, more limited | Robust analytics with GA | | Community Support | Growing but smaller community | Large community and resources |

Pricing Breakdown

When it comes to pricing, both platforms have free tiers, but they scale differently. Here’s a quick breakdown:

Supabase Pricing

• Free Tier: Limited to 500 MB database storage and 2 concurrent connections.
• Pro Plan: $25/month for 8 GB storage, 20 concurrent connections, and additional features.

Firebase Pricing

• Free Tier: Includes basic Firestore usage, up to 1 GB storage, and 50,000 reads/month.
• Blaze Plan: Pay-as-you-go model starts at $25/month based on usage—can get expensive quickly.

Best For: Use Cases

• Choose Supabase if: You need a relational database, want an open-source solution, or prefer SQL queries.
• Choose Firebase if: You require extensive analytics, real-time capabilities, or are already invested in the Google ecosystem.

Limitations and Trade-offs

Supabase Limitations

• Less mature than Firebase, which means fewer tutorials and community resources.
• Limited analytics compared to Firebase.
• Requires more manual setup for some features.

Firebase Limitations

• Can become costly, especially with high traffic.
• No built-in relational database support; relies on NoSQL.
• Lock-in with Google’s ecosystem can be a concern for some builders.

Our Take: What We've Used

In our experience, we’ve tried both platforms for different projects. For a side project that required quick deployment and real-time features, we went with Firebase. It was easy to set up, but we quickly noticed costs climbing as our user base grew.

On the other hand, Supabase has been our go-to for projects where we needed relational data handling. The SQL database structure allowed us more flexibility in queries, and the pricing was more manageable.

Conclusion: Start Here

If you're just starting out or building a small-scale project, both platforms can serve your needs well. However, if you prioritize a relational database and open-source flexibility, Supabase is the better choice for your next project in 2026. On the other hand, if you need extensive analytics and are okay with potential scaling costs, go with Firebase.

What We Actually Use

Currently, for our projects, we lean towards Supabase for its ease of use and pricing structure, especially for side projects and MVPs. If you’re in a similar situation, consider trying Supabase first.
