supabase

Supabase is a cloud service that provisions a full Postgres database for each project, along with a collection of tools that can be used to build web, mobile, and AI applications. The platform offers authentication, data APIs, realtime data streams, edge functions, storage, and vector embeddings, all accessible from a single dashboard. The service can be started for free, with a demo request available for larger projects.

When you begin a new project you select a Postgres database that is immediately available. From that database you can secure user sign‑ups and log‑ins through a built‑in authentication layer that uses Row Level Security. The same database can be queried directly from client code with the Supabase JavaScript SDK; the SDK is imported with `import { createClient } from '@supabase/supabase-js'`. Sample code on the site shows a React component that pulls data from a `todos` table and renders it with a stateless component, demonstrating how the client library interacts with the database. Besides direct queries, the platform offers instant REST APIs that allow external applications to read or write data with standard HTTP requests.

Real‑time capabilities allow developers to build multiplayer or collaborative features. The Realtime service pushes data changes to connected clients instantly. Edge Functions can be written in JavaScript and deployed without managing servers; the platform handles scaling automatically. Vector embeddings for machine‑learning workloads can be stored, indexed, and searched alongside relational data, making Supabase useful for AI‑driven applications. Storage features let you upload large files, videos, images, etc., and serve them directly from the same platform.

The dashboard provides a Table Editor, SQL Editor, and policy editor for Row Level Security, enabling developers to define fine‑grained access rules without leaving the interface. Supabase offers production‑ready templates for frameworks such as React, Next.js, Flutter, and Expo, covering authentication, user management, and subscription models. Customers frequently cite the platform's convergence of many services, database, auth, APIs, realtime, storage, functions, as a reason for adopting it.
