This is the monorepo for Supabase, the open-source Firebase alternative built on PostgreSQL. The repository contains the complete Supabase platform including: (1) Studio - a Next.js-based management dashboard for database, auth, storage, and edge functions, (2) Docs - a Next.js documentation site with MDX content and search, (3) WWW - the main marketing website, (4) UI packages - shared React component libraries built on Radix UI and Tailwind CSS, (5) pg-meta - a TypeScript library for PostgreSQL metadata introspection, (6) ai-commands - AI/LLM integration tools, (7) Docker configurations for self-hosted deployments, and (8) numerous example applications demonstrating Supabase integrations. The architecture is a pnpm monorepo using Turbo for build orchestration. The codebase demonstrates sophisticated engineering patterns including: a custom SQL query builder with branded types for safe SQL composition (pg-meta), a comprehensive component library with design system tokens, real-time features via WebSockets, row-level security policy management, and a multi-tenant organization/project structure. The repository is actively maintained with recent commits and has strong community engagement (105k+ stars).

This is the Supabase JavaScript SDK monorepo, providing isomorphic client libraries for Supabase backend services. It is a well-structured TypeScript monorepo managed with pnpm and Nx, containing six core packages: auth-js (authentication), postgrest-js (database queries via PostgREST), realtime-js (WebSocket-based realtime subscriptions), storage-js (file storage and vector index API), functions-js (edge function invocation), and the umbrella supabase-js package that combines them into a single `createClient()` entry point. The SDK supports multiple runtimes (Node.js, Deno, browsers, Bun, React Native, Cloudflare Workers) and includes optional OpenTelemetry tracing support. The codebase demonstrates high craftsmanship with extensive TypeScript generics for type-safe query building, fluent builder patterns, robust error handling hierarchies, and comprehensive integration tests against local Supabase infrastructure. It is actively maintained with frequent releases, automated CI/CD, and a strong focus on backward compatibility.

This is the official Supabase SSR library (`@supabase/ssr`), a TypeScript package that provides `createBrowserClient` and `createServerClient` functions for using Supabase authentication in server-side rendering frameworks like Next.js, Remix, SvelteKit, and React Router. The library manages user sessions entirely via cookies, handling cookie chunking (splitting large JSON payloads across multiple cookies to respect browser size limits), base64url encoding for safe cookie values, and PKCE code verifier lifecycle. It exposes a `getAll`/`setAll` cookie interface that framework adapters implement to read and write cookies from request/response objects. The server client uses lazy session initialization and writes updated tokens back to cookies on auth state changes, with cache-control headers to prevent CDN caching of auth responses. The package also includes a `clearAuthCookiesAtScopes` migration helper for cleaning up stale cookies after domain/path changes. The codebase is well-tested, actively maintained, and follows modern TypeScript practices with strict mode and no top-level side effects.
