Supabase vs Firebase: which to pick in 2026
Pick Supabase if you want a Postgres-native, open-source backend you can self-host, query with raw SQL, and own your data without vendor lock-in — it wins for teams with relational data models or anyone who has been burned by NoSQL at scale. Pick Firebase if you are building a real-time mobile app, need Google's global CDN and offline sync out of the box, or your team is already deep in the Google Cloud ecosystem and wants zero infrastructure decisions.
Supabase
Free tier available; Pro plan starts at $25/month per project; Team plan at $599/month
Strengths
- Postgres under the hood — full SQL, joins, foreign keys, and extensions like pgvector for AI workloads
- Open-source (Apache 2.0): self-host on your own infra or any cloud, no vendor lock-in
- Row-Level Security (RLS) policies enforced at the database layer, not the application layer
- Auto-generated REST and GraphQL APIs directly from your schema with no extra tooling
- Built-in Auth, Storage, Edge Functions, and Realtime all in one dashboard
- Generous free tier: 500 MB database, 1 GB file storage, 50,000 monthly active users
Best for
- Founders building SaaS products with relational data models (multi-tenant, complex joins)
- Teams migrating off Firebase who hit NoSQL scaling or querying pain
- Engineers who want to run pgvector for AI-powered search without a separate vector DB
- Startups that need full data portability and want to avoid Google lock-in
- Backend developers who prefer writing SQL over learning a proprietary query language
Firebase
Spark plan free; Blaze plan pay-as-you-go (Firestore reads $0.06 per 100K, writes $0.18 per 100K)
Strengths
- Firestore and Realtime Database offer sub-100ms live sync to millions of concurrent clients, battle-tested at Google scale
- First-class offline persistence on iOS, Android, and web — data syncs automatically when connectivity returns
- Firebase App Distribution, Crashlytics, and Performance Monitoring make it a full mobile DevOps platform, not just a database
- Google Cloud Functions integration is mature with cold-start times under 200ms on Gen 2 runtimes
- Firebase Authentication supports 10+ providers (Google, Apple, phone, SAML, OIDC) with no extra config
- Spark (free) plan covers 1 GB Firestore storage and 10 GB/month transfer — enough to validate most MVPs
Best for
- Mobile-first teams building iOS or Android apps that need offline sync
- Consumer apps expecting viral spikes — Firebase scales to zero and to millions without config changes
- Founders who want a single Google Cloud bill and tight integration with BigQuery, AdMob, and Analytics
- Solo developers prototyping real-time features like chat, live cursors, or collaborative docs

Alternatives worth considering
PocketBase
Single Go binary you self-host; zero-cost and ideal for solo founders who want Supabase-like features without a managed service bill
Appwrite
Open-source BaaS with a Docker-based self-host path, strong mobile SDKs, and a more opinionated auth/storage layer than Supabase
Neon
Serverless Postgres with branching — a strong Supabase alternative if you only need the database layer and want per-second billing
AWS Amplify
Firebase equivalent inside the AWS ecosystem; best for teams already on AWS who want managed auth, storage, and GraphQL via AppSync
Convex
Reactive, TypeScript-native backend with real-time queries baked in — worth evaluating if you want Firebase-style reactivity with a typed schema
