Supabase Starter vs Firebase Starter vs Appwrite Starter 2026
Backend-as-a-Service in SaaS Boilerplates
The backend-as-a-service market matured significantly in 2024-2025. Supabase, Firebase, and Appwrite have each become viable starting points for SaaS products — each with official or community Next.js starters.
Choosing between them is not just a database choice. It is a choice about your entire backend philosophy: SQL vs NoSQL, open source vs proprietary, self-hosted vs managed.
TL;DR
- Supabase — Best for SQL, open source, and the broader Next.js ecosystem. The most popular BaaS choice for SaaS boilerplates in 2026. Row-Level Security, PostgreSQL extensions, and Edge Functions. Generous free tier.
- Firebase — Best for real-time applications and Google ecosystem integration. Firestore's NoSQL model and real-time subscriptions are unique. The most mature platform, but proprietary and Google-owned.
- Appwrite — Best for self-hosting and data sovereignty. Open source, runs on Docker, no vendor lock-in. Smaller community, less boilerplate ecosystem support.
Supabase Starters
The Ecosystem
Supabase has the largest Next.js starter ecosystem of the three. The major commercial SaaS boilerplates — Makerkit, Supastarter, and many free templates — are built on Supabase. The @supabase/ssr package and the official Next.js Supabase Starter Kit (by vercel) provide battle-tested patterns.
Official Vercel + Supabase Starter
The most widely used Supabase starter for Next.js:
npx create-next-app -e with-supabase
Includes:
- Supabase Auth with email/password and GitHub OAuth
- Row-Level Security (RLS) policies for data protection
- Server-side auth with
@supabase/ssr - TypeScript with generated Supabase types
What Supabase Provides
| Feature | Supabase |
|---|---|
| Database | PostgreSQL |
| Auth | Email, social OAuth, magic links, MFA, passkeys |
| Real-time | Yes (Postgres changes) |
| File storage | Yes (S3-compatible) |
| Edge Functions | Yes (Deno runtime) |
| Row-Level Security | Yes (native PostgreSQL) |
| Self-hosting | Yes (docker-compose) |
| Free tier | 2 projects, 500MB DB, 1GB storage |
| Open source | Yes (MIT for most components) |
| Vector embeddings | Yes (pgvector extension) |
Why Supabase Dominates the Boilerplate Ecosystem
- SQL is universal. Developers know SQL. Prisma and Drizzle speak SQL. Joining data from multiple tables is natural.
- Row-Level Security is a powerful security primitive that most NoSQL alternatives cannot match.
- PostgreSQL extensions — pgvector for AI embeddings, PostGIS for geospatial data, full-text search — are enormous ecosystem advantages.
- Open source core means you can self-host if you outgrow the managed service or need data residency.
Supabase Boilerplate Compatibility
| Boilerplate | Supabase Support |
|---|---|
| Makerkit | Primary (Next.js Supabase stack) |
| Supastarter | Primary |
| Next.js SaaS Boilerplate | Optional |
| create-t3-turbo | Via Drizzle |
| Open SaaS | PostgreSQL (compatible) |
Firebase Starters
The Ecosystem
Firebase has a large ecosystem but limited direct presence in the SaaS boilerplate space. The reason: Firestore's NoSQL model and the lack of SQL make it less compatible with Prisma/Drizzle, which most TypeScript SaaS boilerplates use.
The Firebase + Next.js pattern exists but is less common than the Supabase equivalent.
Official Firebase + Next.js Starter
Firebase provides a Next.js starter template focused on:
- Firebase Authentication (the most mature auth service in the market)
- Firestore for the database
- Firebase Storage
- Firebase Functions for server-side logic
What Firebase Provides
| Feature | Firebase |
|---|---|
| Database | Firestore (NoSQL) + Realtime Database |
| Auth | The most mature auth service (Google, email, phone, 20+ providers) |
| Real-time | Yes (first-class, best-in-class) |
| File storage | Yes (Firebase Storage / Google Cloud Storage) |
| Edge Functions | Firebase Functions (Node.js, TypeScript) |
| Row-Level Security | Firestore Security Rules (document-level) |
| Self-hosting | No (Google-managed) |
| Free tier | Generous (Spark plan) |
| Open source | No |
| Vector embeddings | Via Google Cloud Vertex AI |
When Firebase Wins
- Real-time applications. Firestore's real-time subscriptions are first-class — no polling, no webhooks, live data updates. For collaborative tools, chat apps, or live dashboards, Firebase's real-time story is unmatched.
- Mobile-first development. Firebase SDKs are native to iOS and Android. If your product has a significant mobile component, Firebase's native mobile SDKs are more mature than Supabase's.
- Google ecosystem. If you are already using Google Cloud, Firebase integrates naturally with Cloud Run, BigQuery, and Google's AI platform.
- Auth provider breadth. Firebase Authentication supports 20+ providers including phone number auth — unmatched breadth for consumer apps.
Firebase SaaS Boilerplate Limitations
- Firestore's NoSQL model does not map well to Prisma or Drizzle — the primary TypeScript ORMs used in Next.js boilerplates
- The lack of SQL queries makes complex relational data models awkward
- Per-read/write pricing at scale can be unpredictable
Appwrite Starters
The Ecosystem
Appwrite is the open-source, self-hostable alternative to both Supabase and Firebase. It provides a comparable feature set — auth, database, storage, functions — but runs on your own infrastructure.
Official Appwrite + Next.js Starter
Appwrite maintains official SDKs and starter templates for Next.js:
- Appwrite Authentication (email, social OAuth, phone)
- Appwrite Databases (document model, like Firestore)
- Appwrite Storage
- Appwrite Functions (server-side logic)
What Appwrite Provides
| Feature | Appwrite |
|---|---|
| Database | Document model (like Firestore, not SQL) |
| Auth | Email, social OAuth, phone, magic links |
| Real-time | Yes (event subscriptions) |
| File storage | Yes |
| Edge Functions | Appwrite Functions |
| Self-hosting | Yes (Docker) |
| Free tier | Free (cloud), unlimited (self-hosted) |
| Open source | Yes (BSD-3) |
| SQL support | No (document model) |
When Appwrite Wins
- Data sovereignty. If your product requires data residency in a specific country or you cannot use third-party SaaS backends, Appwrite self-hosted is the answer.
- Cost at scale. Self-hosted Appwrite has no per-request or per-user fees. For products with predictable infrastructure, this can be significantly cheaper than managed services.
- Compliance requirements. GDPR, HIPAA, and other compliance requirements are easier to satisfy with self-hosted infrastructure.
Appwrite Boilerplate Limitations
- The document database model (not SQL) limits ORM compatibility
- Smaller community and boilerplate ecosystem than Supabase
- Self-hosting requires infrastructure expertise
Head-to-Head Comparison
| Feature | Supabase | Firebase | Appwrite |
|---|---|---|---|
| Database model | SQL (PostgreSQL) | NoSQL (Firestore) | Document (NoSQL) |
| ORM compatibility | Excellent (Prisma, Drizzle) | Poor (no SQL) | Limited |
| Real-time | Good (Postgres changes) | Excellent (native) | Good |
| Auth providers | Good (10+ providers) | Excellent (20+ providers) | Good |
| Self-hosting | Yes | No | Yes |
| Open source | Yes | No | Yes |
| Vendor lock-in | Low | High | Low |
| Free tier | Good | Good | Very generous |
| SaaS boilerplate support | Excellent | Limited | Limited |
| Next.js ecosystem fit | Excellent | Moderate | Moderate |
| AI/vector support | Yes (pgvector) | Yes (Vertex AI) | No |
| Community size | Large and growing | Very large | Growing |
The Recommendation
For Next.js SaaS boilerplates in 2026, Supabase is the default recommendation. The SQL model, the RLS security layer, the pgvector extension for AI features, and the large boilerplate ecosystem make it the best-supported choice for the developer audience using commercial and open-source starters.
Choose Firebase if: Your product is real-time-first (collaborative tools, chat, live dashboards) and you are comfortable with NoSQL and Google's pricing model.
Choose Appwrite if: You need to self-host for compliance or cost reasons, and you accept the trade-off of a smaller ecosystem and document (not SQL) database.
