Supabase vs Firebase
Two popular backend-as-a-service platforms for web and mobile apps. Here's an honest comparison across database, auth, real-time, pricing, and lock-in.

الإجابة المختصرة
Choose Supabase if you want a relational Postgres database with SQL, open-source portability, and less vendor lock-in. Choose Firebase for a mature, fully managed platform with deep Google integration and strong mobile SDKs, especially for document-style data. Both offer auth, real-time, storage, and serverless functions.
Supabase vs Firebase في لمحة
| المعيار | Supabase | Firebase |
|---|---|---|
| Best for | Apps that want SQL/Postgres and open-source portability | Mobile-first apps and rapid prototyping in the Google ecosystem |
| Database | PostgreSQL (relational, full SQL) | Firestore / Realtime DB (NoSQL document store) |
| Querying | Full SQL, joins, views, and Postgres extensions | Document queries; joins and complex queries are limited |
| Real-time | Real-time subscriptions on Postgres changes | Real-time is a core, mature strength |
| Auth | Built-in auth with row-level security policies | Mature auth with many providers and tight SDK integration |
| Functions | Edge Functions (Deno/TypeScript) | Cloud Functions (Node, Python, and more) |
| Open source & portability | Open-source; self-hostable on standard Postgres | Proprietary; data and logic are tied to Google Cloud |
| Pricing model | Predictable tiers; Postgres-based usage | Pay-as-you-go on reads, writes, and storage |
| Maturity & ecosystem | Younger, growing fast; standard SQL tooling works | Very mature, large ecosystem, deep Google integration |
متى تختار Supabase
- You want a relational database and full SQL.
- Open-source and the option to self-host matter to you.
- You want to minimise vendor lock-in.
- Your data is relational with meaningful joins and constraints.
متى تختار Firebase
- You're building mobile-first and want mature, polished SDKs.
- Your data fits a document model and needs heavy real-time sync.
- You're already invested in Google Cloud and its services.
- You want a battle-tested platform with a large ecosystem.
كيف نقرر
We ship production apps on both. At SummationWorks we often reach for Supabase when an app benefits from relational data, SQL, and portability, and Firebase when a project is mobile-first or already in the Google ecosystem. We recommend based on your data model and product, not a default. See our web development services or أخبرنا عن مشروعك.

الأسئلة الشائعة
Is Supabase better than Firebase?
Neither is universally better. Supabase gives you a relational Postgres database, full SQL, and open-source portability with less lock-in. Firebase is a more mature, fully managed platform with excellent mobile SDKs and real-time, especially for document-style data. The right choice depends on your data model and stack.
Is Supabase a true Firebase alternative?
Yes. Supabase offers the same core building blocks — database, authentication, real-time subscriptions, storage, and serverless functions — which is why it's positioned as an open-source Firebase alternative. The main difference is a relational Postgres database instead of a NoSQL document store.
Which is cheaper, Supabase or Firebase?
It depends on usage. Firebase's pay-as-you-go billing on reads, writes, and storage can grow unpredictably at scale, while Supabase's Postgres-based tiers tend to be more predictable. Model your real workload before deciding, as either can be cheaper for a given app.
Can I self-host Supabase or Firebase?
Supabase is open-source and can be self-hosted on standard PostgreSQL infrastructure. Firebase is proprietary and runs only on Google Cloud, so you cannot self-host it — that's a key consideration if avoiding vendor lock-in matters to you.
Which should I choose for a mobile app?
Firebase has long been a strong default for mobile thanks to its mature SDKs and real-time database, especially for document-style data. Supabase is fully capable for mobile too and is the better fit when you want relational data and SQL. Pick based on your data model.
