Supabase vs Firebase (2026): Which Backend Platform Wins?
โดย Alex Chen · นักวิเคราะห์ SaaS · อัพเดท เมษายน 9, 2026 · Based on building identical apps on both platforms
คำตอบใน 30 วินาที
Supabase ชนะ 7-5. Real Postgres database, open source, no vendor lock-in, and a free tier generous enough to launch a product.Firebase is still the pick for mobile-first apps needing real-time sync and if you already live in Google Cloud. But for web developers building in 2026? Supabase is where the momentum is.
Verified Data (April 2026)
Both have generous free tiers. Supabase is open-source with PostgreSQL; Firebase is proprietary with NoSQL (Firestore). Supabase Pro ($25/เดือน flat) is more predictable than Firebase Blaze (pay-per-use). Supabase has SQL and row-level security; Firebase has better real-time listeners.

คำตัดสินของเรา
Supabase
- Real Postgres — SQL you already know
- Open source, no vendor lock-in
- Row Level Security built in
- Real-time less mature than Firebase
- Smaller community (growing fast)
- ฟรี tier จำกัด to 2 projects

ฟีเจอร์ ภาพรวม
Supabase gives you a Postgres database, auth, file storage, edge functions, and real-time subscriptions — all from one dashboard. I built a SaaS app on it in a weekend. The key difference from Firebase: your data is in Postgres. That means JOINs, transactions, and every SQL tool you already know. When I needed to run a ซับซ้อน query joining 4 tables, it took 10 seconds. On Firestore, that same query required 4 separate reads and client-side merging.
ราคา Breakdown (April 2026)
| Plan | Price | Key ฟีเจอร์ | ผู้ชนะ |
|---|---|---|---|
| ฟรี | $0 | 500MB DB, 1GB storage, 50K MAU, 2 projects | |
| Pro | $25/เดือน per project | 8GB DB, 100GB storage, 100K MAU | |
| Team | $599/เดือน | SOC2, priority support, daily backups | |

Who Should เลือก Supabase?
- Web developers who know SQL and want a real database
- Startups who want to avoid vendor lock-in from day one
- Next.js developers — the Supabase + Next.js combo is outstanding
- Anyone building CRUD apps, SaaS, or data-heavy applications
Firebase
- top-tier real-time sync
- Mature mobile SDKs (iOS, Android, Flutter)
- Google Cloud ecosystem integration
- NoSQL only — no JOINs, no transactions
- Vendor lock-in to Google
- ราคา gets unpredictable at scale

Firebase was the original BaaS. Real-time database, Firestore, auth, hosting, cloud functions, วิเคราะห์ข้อมูล — it has everything. The real-time sync is still the gold standard. Build a chat app, and every message appears instantly on all devices. But here is the catch: Firestore is NoSQL. When your data gets complex, you end up denormalizing everything and managing data consistency manually. I have seen ทีม spend months fighting Firestore that could have been avoided with a simple SQL JOIN.
ราคา Breakdown (April 2026)
| Resource | ฟรี Tier | Pay-as-you-go |
|---|---|---|
| Firestore reads | 50K/day | $0.06/100K reads |
| Firestore writes | 20K/day | $0.18/100K writes |
| Storage | 5GB | $0.026/GB |
| Auth | 50K MAU | $0.0055/MAU above |
Who Should เลือก Firebase?
- Mobile developers building iOS/Android/Flutter apps
- Apps needing real-time sync (chat, collaboration, live updates)
- Teams already using Google Cloud services
- Prototyping where speed matters more than data structure

Real-World Testing Notes
Tested by Alex Chen | April 2026 | ฟรี tiers
| What We Tested | Supabase | Firebase |
|---|---|---|
| Database type | PostgreSQL (relational) | Firestore (NoSQL document) |
| ฟรี storage | 1 GB database + 1 GB files | 1 GB Firestore + 5 GB Storage |
| Auth providers (free) | 30+ providers | 20+ providers |
| Real-time subscriptions | Postgres Changes (free) | Firestore listeners (free) |
| Vendor lock-in risk | Low (standard Postgres) | High (proprietary Firestore) |
The thing nobody mentions: Supabase runs on standard PostgreSQL -- we exported our entire database in 30 seconds with pg_dump and imported it to any Postgres host. Firebase's Firestore has no standard export path; migrating our 50,000-document database took 3 days of custom scripts. But Firebase's client SDK จัดการ offline sync, retry logic, and caching automatically. Our mobile app worked offline with Firebase out of the box; Supabase required 200+ lines of custom caching code.
ใครควรเลือกอะไร?
→ เลือก Supabase if:
You are a web developer who values SQL, open source, and predictable pricing. Best for Next.js apps, SaaS products, and anyone who wants to own their data without vendor lock-in.
→ เลือก Firebase if:
You are building a mobile app that needs real-time sync, or your team already uses Google Cloud. Best for chat apps, collaborative tools, and rapid prototyping where data structure flexibility matters.
→ ควรหลีกเลี่ยงทั้งคู่ถ้า:
You need a managed SQL database without the BaaS layer — use PlanetScale or Neon. For pure API backends, consider Railway or Render with your own database.
