You can avoid running servers by using a pre-made backend provided by Firebase and Supabase. A NoSQL database with serverless, storage, and authentication tools is used by Firebase (a product of Google). Based on Postgres, Supabase is an open-source alternative that provides comparable functionality but adds SQL and self-hosting capabilities. Your data model, scaling requirements, and degree of vendor lock-in avoidance will all influence your decision.
What is Supabase?
Supabase is an open-source backend built on Postgres. Every project gets its own Postgres database, plus auto-generated REST and GraphQL APIs, real-time updates, and storage. It uses Row-Level Security (RLS) written in SQL to control who can access what data. Since it’s based on open tools like Postgres and GoTrue, you can run Supabase locally or host it yourself with Docker, Kubernetes, or Terraform.
What is Firebase?
Firebase is a Google-managed platform that includes Cloud Firestore (a NoSQL document database), authentication, Cloud Storage for files, and Cloud Functions for backend code. Firestore stores data as JSON-like documents inside collections and works offline by caching data on the device, syncing changes when back online. It supports collection group queries to search across collections with the same name. Since it’s NoSQL, handling relational data often means denormalizing documents or running several queries in your code.
