Best Supabase Alternatives 2026
Discover the best Supabase alternatives for 2026. Compare Firebase, Appwrite, PocketBase, Neon + Auth.js and Convex on features, pricing and flexibility.
At MG Software, we use Supabase as our primary BaaS platform. As an alternative, we recommend Firebase for mobile apps with offline sync, and PocketBase for rapid prototypes and MVPs.
Why do people look for alternatives to Supabase is an open-source Backend-as-a-Service built on PostgreSQL with realtime subscriptions, Row Level Security, built-in auth, storage, edge functions and auto-generated APIs. It positions itself as an open-source Firebase alternative.?
Developers seek Supabase alternatives when they don't want PostgreSQL, prefer a fully serverless model, need more control over backend architecture, or miss specific features like Firebase's offline sync or Convex's reactive data model.
Best alternatives
Firebase
Google's fully managed app development platform with Firestore (NoSQL), Authentication, Cloud Functions, Hosting, Cloud Messaging and comprehensive mobile SDKs.
Pros
- +Mature platform with comprehensive mobile SDKs and offline sync
- +Seamless integration with Google Cloud Platform and other Google services
- +Generous free tier (Spark plan) for prototyping and small apps
Cons
- -Strong vendor lock-in — migrating from Firestore is complex
- -NoSQL model (Firestore) limits complex queries and joins
Appwrite
Open-source Backend-as-a-Service with database, authentication, storage, functions and realtime — self-hostable or as a cloud service with support for 10+ programming languages.
Pros
- +Fully open-source and self-hostable for maximum control
- +SDKs for 10+ languages including Flutter, React Native and Swift
- +Built-in auth with 30+ OAuth providers and team management
Cons
- -Database is document-based — no SQL or relational features
- -Smaller ecosystem and community than Supabase or Firebase
PocketBase
Ultra-compact open-source backend in a single Go binary with built-in SQLite database, realtime subscriptions, authentication and an admin dashboard.
Pros
- +Single binary — no Docker, no dependencies, deploys in seconds
- +Built-in auth, realtime and file storage without external services
- +Extremely low hosting costs on any VPS or edge location
Cons
- -SQLite limits horizontal scalability for high concurrency
- -No serverless functions — custom logic requires external integration
Neon + Auth.js
Serverless PostgreSQL (Neon) combined with Auth.js (formerly NextAuth.js) as the authentication layer, for teams wanting to build a modular backend stack.
Pros
- +Full PostgreSQL power with serverless scalability and branching
- +Flexible choice of auth, ORM and API layer — no vendor lock-in
- +Neon's database branching makes dev/staging/production workflows easy
Cons
- -Requires assembling auth, storage and realtime layers yourself
- -More configuration and maintenance than an all-in-one BaaS platform
Convex
Reactive backend platform with a TypeScript-first approach, automatic caching, realtime queries and serverless functions in one integrated environment.
Pros
- +Reactive queries — UI updates automatically on data changes
- +TypeScript end-to-end with full type safety from database to frontend
- +No caching logic needed — Convex handles invalidation automatically
Cons
- -Proprietary data model — no standard SQL or PostgreSQL access
- -Relatively new platform with a smaller ecosystem
What to consider when switching?
- Determine whether you need PostgreSQL/SQL or a document/reactive model suffices
- Compare built-in features (auth, storage, functions) per platform
- Evaluate self-hosting capabilities versus vendor-managed cloud service
- Assess SDK support for your frontend framework and mobile platforms
