How to Self-Host Supabase on Contabo VPS with Docker: Complete Open-Source Firebase Guide

Why Developers Are Migrating from Firebase to Supabase

While Google Firebase popularized real-time cloud data, its NoSQL Firestore architecture makes complex relational queries and joins painfully difficult. Supabase provides an open-source alternative built on the enterprise foundation of PostgreSQL, providing automatic REST and GraphQL APIs, real-time WebSockets, and powerful Row-Level Security (RLS).

Deploying Self-Hosted Supabase on Contabo VPS

Clone the official Supabase Docker repository:

git clone --depth 1 https://github.com/supabase/supabase
cd supabase/docker
cp .env.example .env

Generate secure JWT secrets and set your database passwords inside .env:

# Generate secrets
openssl rand -hex 32

# Launch the entire Supabase stack
docker compose pull
docker compose up -d

Open Supabase Studio at http://YOUR_CONTABO_IP:8000 to access the visual table editor, SQL query runner, and user authentication portal.
