PocketBase vs Firebase: A Complete Comparison and the Secret Weapon for MVPs in 2025

Introduction

In the world of startups and digital products, time is the main resource. The faster you ship an MVP (minimum viable product), the sooner you get market feedback and can correct course. In 2025, PocketBase has become our secret weapon for ultra-fast project launches.

What Is PocketBase?

PocketBase is an open-source backend-as-a-service (BaaS) that ships as a single executable file. Everything you need is already inside:

• SQLite database — reliable data storage
• Authentication system — sign-up, login, OAuth (Google, GitHub, etc.)
• File storage — uploading images and documents
• Real-time subscriptions — instant data updates
• REST API — automatically generated for all collections
• Admin panel — a convenient interface for managing data

All of this launches with a single command and weighs about 15 MB. When idle, PocketBase consumes only 100-150 MB of RAM. For comparison: a self-hosted Supabase stack can require several GB of RAM just to stay idle, since it bundles Postgres, Studio, Realtime, Auth, and Storage as separate containers — a heavier footprint that calls for a more powerful server.

Why PocketBase Instead of Firebase or Supabase?

1. Full Control Over Your Data

Unlike cloud services, PocketBase runs on your server. What does that mean for a business?

The choice of infrastructure is entirely yours:

• Rent a VPS from any provider: AWS, DigitalOcean, Hetzner, Linode, or a local host
• Host it on the company's own server — for maximum confidentiality
• Easily move between hosts when needed — the data is always yours

Why this matters:

• Compliance with data-protection regulations — the data stays where you choose
• No third-party provider can shut down or restrict access to your service
• Full access to the database at any moment
• Independence from the pricing policy of cloud providers

2. Zero Operating Costs

Firebase is priced by the number of operations and volume of data — as a project grows, the bills can scale up quickly. PocketBase is free: you only pay for hosting (from around $6/month for a VPS).

3. A Minimal Barrier to Entry

To launch PocketBase, a single terminal command is enough. One file — no Docker containers, Kubernetes, or complex configurations to get started. Even a junior developer can handle it.

For comparison: Firebase and Supabase require registration, project setup in a cloud console, and working with CLI utilities. PocketBase can be deployed in 5 minutes.

4. Official SDKs for React and Flutter

PocketBase works great with both frameworks we actively use. There are official SDKs:

• JavaScript/TypeScript SDK — for React, Next.js, Vue
• Dart SDK — for Flutter (iOS, Android, Web)

This lets us use a single backend for web apps built with React and mobile apps built with Flutter.

When PocketBase + Node.js?

PocketBase covers 80% of the tasks of a typical application. However, there are scenarios where we add Node.js to the mix:

Payment System Integration

Connecting Stripe, PayPal, or other payment gateways requires server-side logic to handle webhooks and verify signatures. For this we use a Node.js microservice alongside PocketBase.

Complex Business Logic

If you need queue processing, deferred tasks, or integration with external APIs (CRM, ERP) — Node.js complements PocketBase.

A Typical Architecture

In a typical project, React/Next.js (web) and Flutter (mobile app) connect to PocketBase for authentication, data handling, files, and real-time updates. When needed, Node.js handles payments, webhooks, and integrations with external services.

Our Cases Built on PocketBase

MomConnect — a social platform for parents

Stack: React + PocketBase

MomConnect is a platform for parents to communicate, with real-time chat, user profiles, and content sharing. Thanks to PocketBase:

• Chat works instantly — real-time subscriptions deliver messages in milliseconds
• Sign-up in 30 seconds — built-in authentication with email verification
• Photo uploads — built-in storage with automatic resizing

Building the MVP took 6 weeks instead of the expected 3 months.

SDK for React	Yes	Yes	Yes

When NOT to Use PocketBase?

PocketBase is an excellent choice for MVPs and mid-scale projects. However, there are limitations:

High Load (More Than 10,000 RPS)

What is RPS? Requests Per Second — the number of requests per second. In plain terms: if 1,000 users simultaneously open pages, click buttons, and send messages, this creates thousands of server requests every second.

To grasp the scale: 10,000 RPS is roughly 100,000+ active users online at the same time. That's the level of large marketplaces. For 99% of startups and business apps, such a load is unrealistic at the start.

The SQLite Database

SQLite is a lightweight embedded database. It has limitations on complex queries, but for most projects it is more than enough. SQLite supports indexes, transactions, and full-text search. Important: Firebase has no SQL interface at all — only NoSQL, which limits query flexibility.

Horizontal Scaling

PocketBase runs as a single instance, without a cluster. But that doesn't make it weak. A single instance on a server with 16 GB of RAM and 8 CPU cores can serve:

• Tens of thousands of registered users
• Thousands of concurrent connections
• Millions of records in the database

This is more than enough for most commercial projects. By the time you grow to scales requiring horizontal scaling, you'll already have the resources to migrate.

Conclusion

PocketBase in 2025 is a Swiss Army knife for a fast start. It lets you launch a full-featured application with authentication, a database, and real-time features in days rather than months.

We successfully use it both for React projects (MomConnect) and for Flutter apps. And when payment-system integration or a complex backend is needed, we add Node.js to the mix.
