Best Libraries for Supabase in 2026

The official JavaScript/TypeScript client. Handles auth, database queries, storage, and real-time subscriptions. Type-safe when paired with generated types. The starting point for any web project.

Full-featured client with type-safe database queries

Server-side rendering helpers for Next.js, SvelteKit, and Remix. Handles cookie-based auth sessions correctly across server and client. Replaces the old auth-helpers packages.

Cookie-based auth that works correctly with SSR frameworks

Official Flutter SDK with support for all Supabase features. If you're building a cross-platform mobile app with a Supabase backend, this is well-maintained and keeps parity with supabase-js.

Full feature parity with supabase-js for cross-platform mobile

Official Swift client for iOS and macOS apps. Covers auth, database, storage, and real-time. The API mirrors supabase-js closely, so knowledge transfers between platforms.

Community Kotlin Multiplatform client for Android, iOS, and JVM. Covers core Supabase features with Kotlin coroutines. Solid alternative if your mobile team is Kotlin-first.

Local development, database migrations, type generation, and Edge Function deployment. The CLI is essential — run supabase gen types to get TypeScript types from your database schema.

Generate TypeScript types directly from your database schema

Pre-built auth components for React and other frameworks. Drop in a login form with social providers, magic links, and email/password in one component. Customizable with Tailwind or custom CSS.

Complete auth UI in one component — social, magic link, email

Supabase's built-in auth system supports 20+ OAuth providers, magic links, phone auth, and email/password. Row Level Security integrates auth directly with database permissions. Powerful and free.

20+ OAuth providers with RLS-integrated database permissions

Encrypted secrets storage built into Supabase. Store API keys, tokens, and sensitive configuration encrypted at rest in Postgres. Access from Edge Functions or server-side code.

Supabase's Postgres extension that exposes your database as a GraphQL API automatically. Schema reflects your tables, RLS policies apply, and it runs at the database level for maximum performance.

Auto-generated GraphQL API from your Postgres schema

The older framework-specific auth helpers for Next.js, SvelteKit, and Remix. Being replaced by @supabase/ssr but still used in many existing projects. Migrate when you can.

A TypeScript ORM that works beautifully with Supabase Postgres. SQL-like syntax with full type inference. Use drizzle-kit for migrations alongside Supabase's migration system.

Type-safe SQL queries that feel natural with Supabase

The most popular TypeScript ORM works with Supabase Postgres out of the box. The Prisma schema is a great way to model your data, though you lose some Supabase-specific features like RLS integration.

A type-safe SQL query builder that generates Supabase-compatible queries. More low-level than Drizzle or Prisma — you write SQL, but with TypeScript autocompletion and type checking.

Supabase's vector similarity search extension for building AI features. Store embeddings alongside your data and query by similarity. Powers RAG applications, semantic search, and recommendations.

Vector similarity search for AI features — built into Postgres

The engine behind Supabase's auto-generated REST API. Turns your Postgres tables into RESTful endpoints with filtering, pagination, and RLS enforcement. Understanding PostgREST helps you master Supabase's API layer.

Supabase's built-in migration system via the CLI. Write SQL migrations, version them in git, and apply them across environments. Simple and database-native — no ORM abstraction layer.

Built-in real-time engine that broadcasts database changes, presence information, and custom events over WebSockets. Subscribe to row-level changes with RLS enforcement. No additional server needed.

Real-time database changes over WebSockets with RLS

Deno-based serverless functions deployed globally on Supabase's infrastructure. Handle webhooks, run background tasks, and build APIs close to your database. Cold starts are fast and deployment is instant.

Deno functions deployed globally — instant deployment

Schedule recurring database tasks directly in Postgres. Run cleanup jobs, send reminders, aggregate analytics — all without an external scheduler. Cron expressions, database-native.

Message queues built into Postgres via the pgmq extension. Reliable job processing without Redis or RabbitMQ. Process tasks asynchronously from Edge Functions or external workers.

Message queues in Postgres — no Redis needed

S3-compatible file storage with automatic image transformations, resumable uploads, and RLS policies. Upload directly from the client with signed URLs. Handles avatars, documents, and media files.

S3-compatible storage with built-in image transformations

Trigger HTTP webhooks on database events — inserts, updates, and deletes. Call external APIs, send notifications, or sync data without polling. Configure via the dashboard or SQL.

The built-in database admin UI with a table editor, SQL editor, and visual schema designer. Surprisingly powerful for an included tool. Most tasks that require pgAdmin can be done here instead.

Full database admin UI included — rarely need pgAdmin

Run the full Supabase stack locally with Docker via supabase start. Auth, database, storage, and Edge Functions all running on your machine. Test everything before pushing to production.

Preview branches that create isolated Supabase environments for each git branch. Test database changes and migrations in isolation before merging. Like Vercel preview deployments but for your backend.

Isolated backend environments per git branch

Model Context Protocol server for Supabase that lets AI assistants interact with your database, run queries, and manage resources. Connect Claude or other AI tools directly to your Supabase project.

A package manager for Postgres extensions hosted by Supabase. Install community extensions like pgvector, pg_graphql, and others directly into your Supabase project with a single command.

Supabase's Postgres connection pooler built in Elixir. Handles thousands of concurrent connections without overwhelming your database. Transparent to your app — just change the connection string.
