How Supabase Works

Supabase’s architecture and philosophy are built around leveraging best-of-breed open-source tools, ensuring scalability, and making them remarkably simple for developers to use.

Core Philosophy and Design Principles

Supabase’s approach is to choose open source tools which are scalable and make them simple to use. Instead of reinventing the wheel, Supabase prefers to extend an existing tool rather than adding a new one. This commitment extends to its product design, where each product on the Supabase platform is designed to 10x the other products.

Key design principles include:

• Standalone Tools: Each system within Supabase must work as a standalone tool with as few moving parts as possible.
• Integration via APIs and Webhooks: For seamless integration, each Supabase tool should expose an API and Webhooks.
• Developer Primitives: Supabase provides primitives for developers, empowering them to build with flexibility.
• Portability and Standards: Supabase makes it easy to migrate in and out. It uses existing standards like pg_dump and CSV files to increase portability. If a new standard emerges that competes with a ""Supabase"" approach, Supabase will deprecate its approach in favor of the standard.
• Upstreaming: Supabase supports efforts to upstream missing functionality to the original open-source projects.

Postgres at the Heart

The core of Supabase is Postgres. Unlike some BaaS solutions that might abstract the database layer heavily, Supabase does not abstract the Postgres database. Users can access their Postgres database and use it with full privileges through Supabase. The goal is to provide tools that make Postgres as easy to use as Firebase, without sacrificing the power and flexibility of the world’s most trusted relational database. Every Supabase project is a full Postgres database, which is 100% portable, features Built-in Auth with RLS, and is easy to extend.

Architectural Components

Each Supabase project consists of several integrated tools:

• Supabase Studio: An open-source Dashboard for managing your database and services. It provides a user-friendly interface for tasks that would otherwise require direct database interaction.
• GoTrue: A JWT-based API for managing users and issuing access tokens. GoTrue integrates seamlessly with PostgreSQL’s Row Level Security and the API servers, forming the backbone of Supabase Authentication.
• PostgREST: A standalone web server that turns your Postgres database directly into a RESTful API. This is how Supabase provides its instant APIs.
• GraphQL API: Supabase uses PostgREST with its pg_graphql extension to provide a GraphQL API, offering flexibility in data fetching.
• Supabase Realtime: A scalable WebSocket engine built to manage user Presence, broadcast messages, and stream database changes directly to connected clients.
• Supabase Storage API: An S3-compatible object storage service that intelligently stores metadata in Postgres, allowing for fine-grained access control using Postgres permissions.
• Edge Functions (Deno): Supabase uses Deno, a modern runtime for JavaScript and TypeScript, for its Edge Functions, allowing developers to deploy custom logic geographically close to their users.
• postgres-meta: A RESTful API specifically for managing your Postgres database. It can fetch tables, add roles, and run queries, powering much of the Supabase Dashboard.
• Supavisor: A cloud-native, multi-tenant Postgres connection pooler. It helps manage and scale database connections efficiently.
• Kong: Supabase uses Kong as a cloud-native API gateway, built on top of NGINX, to manage and secure API traffic.

Open Source Ethos and Community

Supabase is deeply committed to the open-source world. It builds for developers and supports existing tools and communities wherever possible. This collaborative approach involves working with the community of each tool it uses, employing maintainers, sponsoring projects, investing in businesses, and developing its own open-source tools. This ensures that Supabase not only benefits from the open-source ecosystem but also contributes back to it. Furthermore, Supabase’s cloud offering is compatible with its self-hosted product, giving developers ultimate control.

Supabase vs. The Competition: The Firebase Alternative

When developers consider a Backend-as-a-Service (BaaS) platform, Google’s Firebase often comes to mind. Supabase explicitly positions itself as an open source Firebase alternative, and this comparison is central to understanding its value proposition.

While Firebase is a mature and feature-rich platform, Supabase offers several compelling distinctions:

• Open Source: This is perhaps the most significant differentiator. Supabase’s open-source nature provides transparency, community-driven development, and the ability to self-host, giving developers greater control and avoiding vendor lock-in.
• Postgres at the Core: Firebase primarily uses NoSQL databases (Firestore and Realtime Database). Supabase, on the other hand, gives you a full-fledged PostgreSQL database. This is a major advantage for applications requiring complex relational data, transactions, and the extensive ecosystem of Postgres extensions.
• No Abstraction of Database: Supabase provides direct access to Postgres with full privileges. This means developers aren’t limited by an abstraction layer and can leverage the full power of SQL and Postgres features.
• Portability: Supabase emphasizes ease of migration in and out, using standard tools like pg_dump.

Both Supabase and Firebase aim to simplify backend development by providing authentication, databases, storage, and serverless functions. However, Supabase’s commitment to open source and the power of PostgreSQL offers a distinct choice for developers who value flexibility, control, and the robustness of a relational database.

Integrating Supabase: Challenges and How MetaCTO Can Help

While Supabase is designed to be developer-friendly, integrating any backend service into a mobile or web application can present challenges, especially as projects scale or have unique requirements.

Potential Hurdles in Supabase Integration

Some documented challenges, particularly for those new to Supabase or managing production applications, include:
