Supabase

Supabase is an open source Firebase alternative. It provides a dedicated PostgreSQL database, packaged with Authentication, Realtime subscriptions, Storage, and Edge Functions.

When to Use

• Rapid Application Development: Get Auth + DB + APIs in 5 minutes.
• Postgres Power: Unlike Firebase, you have full SQL power (JOINs, aggregation).
• Realtime: Subscribe to DB changes via WebSockets.
• Vector/AI: Highly integrated pgvector support for AI apps.

Quick Start (JS)

import { createClient } from "@supabase/supabase-js";

const supabase = createClient("https://xyz.supabase.co", "public-anon-key");
