What are Firebase and Supabase?
Firebase is a cloud-based platform that provides backend services for applications. Think of it as a complete toolkit that handles everything your app needs on the server side. Instead of building your own servers, databases, and authentication systems from scratch, Firebase gives you ready-to-use services.
The platform includes a real-time database where your app data updates instantly across all devices. It has user authentication that works with email, phone numbers, Google, Facebook, and other providers. Firebase also offers cloud storage for images and files, push notifications to reach users, crash reporting to find bugs, and performance tracking to see how your app runs.
All these services work together smoothly. You can pick only what you need, making it flexible for any project size from small hobby apps to large business applications.
Supabase is a complete backend platform that gives you all the tools needed to build modern applications. At its core is a Postgres database, which is known for being stable and feature-rich. You can store data, create tables, and manage relationships without writing complex code.
Beyond the database, Supabase includes user authentication with support for email, social logins, and phone numbers. It also has file storage for images and documents, real-time features for live updates, and edge functions to run custom code. Everything connects through simple APIs that are automatically created from your database structure.
What makes Supabase different is that it is completely open-source. You can host it yourself or use their cloud service, and you never get locked into their platform.

Pricing of Firebase and Supabase
Firebase offers two main pricing plans to fit different needs. The Spark Plan is completely free and includes generous limits perfect for small apps and testing. You get unlimited basic features with no payment needed, including authentication, analytics, and limited database usage.
The Blaze Plan uses pay-as-you-go pricing where you only pay for what you use beyond the free limits. This plan includes all the free tier benefits plus unlimited usage. For example:
Cloud Firestore: Free up to 50K reads per day, then pricing starts based on usage
Cloud Functions: Free up to 2 million calls per month, then $0.40 per million
Storage: Free up to 5GB, then $0.026 per GB
Hosting: Free up to 10GB storage and 360MB daily transfer, then minimal fees
Most Firebase services stay free even on the Blaze plan if you stay within the included free limits. You can set spending caps to control costs and avoid surprise charges.
Supabase offers flexible pricing to suit different project sizes and needs.
