Supabase vs Firebase vs PocketBase: Best Backend for Your Next Project

The backend is the part of your app users never see but always feel — the database, authentication, and storage that make it actually work. In 2026, three names dominate the "backend without the pain" conversation: Supabase, Firebase, and PocketBase. They take genuinely different approaches, and the right choice depends on your scale, your budget, and how much control you want. Here's how they compare for your next project.

Quick Verdict

• Best all-round for most projects: Supabase
• Best for real-time and Google ecosystem: Firebase
• Best for small, self-hosted projects: PocketBase

Supabase is the balanced default (SQL, predictable pricing, open source). Firebase is the battle-tested Google option with unmatched real-time features. PocketBase is a brilliant single-file backend for small apps you want to host yourself.

Pricing Compared (Verified July 2026)

Backend	Free tier	Paid	Pricing model
PocketBase	Free (open source)	$0 (self-hosted)	You pay only for your server
Supabase	Generous free	Pro — ~$25/mo per project	Predictable flat tiers
Firebase	Spark (free, limited)	Blaze — pay-as-you-go	Billed per operation

Verified July 2026. Supabase offers predictable flat pricing; Firebase bills per read/write/storage, which can spike as you grow; PocketBase is free software you host yourself (you only pay for the server). Confirm current pricing before building.

The pricing story matters more than it looks. Supabase's flat tiers make costs predictable. Firebase's per-operation billing can surprise growing teams — the same workload that costs ~$50–100/month on Supabase can run into the hundreds on Firebase at scale.

Database and Developer Experience

Supabase is built on PostgreSQL — a real, standard SQL database. That means portability (your data isn't locked into a proprietary format), powerful queries, and easy migration later. It also bundles auth, storage, and instant APIs. For most web apps, it's the most flexible starting point.

Firebase uses a NoSQL document database (Firestore). It's exceptional for real-time syncing — think live chat and collaborative apps — and has the deepest mobile SDK support. The trade-offs are the proprietary data model and the usage-based bill.

PocketBase is a single Go binary with an embedded SQLite database, auth, file storage, and an admin UI built in. It's astonishingly simple to run for small-to-medium apps, but it's designed to run on one server, so it's not built for massive horizontal scale.

Which Should You Choose?

• Choose Supabase if you want a flexible, SQL-based backend with predictable pricing and no lock-in — the best default for most web apps. It's the backend behind many AI website builders, too.
• Choose Firebase if real-time features and deep mobile support are central, and you're comfortable with usage-based billing and Google's ecosystem.
• Choose PocketBase if you're building a small project and want a free, self-hosted backend you fully control.

Frequently Asked Questions

Is Supabase really cheaper than Firebase? For most mid-scale apps, yes — often 30–50% cheaper — because it uses flat pricing instead of billing per database operation. Firebase can be cheaper at very small scale but gets less predictable as you grow.

Can I move away later? Supabase uses standard PostgreSQL, so your data is portable. Firebase's proprietary model makes migration harder. PocketBase uses SQLite, which is also easy to export.

Which is best for a beginner? Supabase strikes the best balance of power and ease, with excellent docs. PocketBase is the simplest to run for a small project. Firebase is great if you're building mobile-first.

Bottom Line

Supabase is the best all-round backend for most projects in 2026, Firebase leads on real-time and mobile, and PocketBase is the ideal lightweight, self-hosted option. Pick based on scale and how much you value predictable pricing and data portability. Explore more in our Developer Tools category.
