3The platform is ISO/IEC 27001:2022 certified and SOC2 Type 2 compliant, with HIPAA alignment for Team and Enterprise plans.
4Daily backups are retained for 7 days on Pro plans, 14 days on Team plans, and up to 30 days on Enterprise plans.

Stork’s verdict on Supabase

Supabase gives you a fully managed Postgres backend with instant APIs, but adopting the whole platform means committing to their opinionated stack.

Stork Quadrant

Becomes the API· 57/100

Replaceable as a UI, but kept alive as the API the agents call.

Confidencehigh(3 runs · ±0)

“Supabase is infrastructure, not a UI — and infrastructure compounds. The LLM can write the SQL, but it can't run the Postgres instance, manage the auth tokens, store the files, or fire the realtime events. The MCP server is a smart move: it makes Supabase the backend agents call, not the thing agents replace. Brand is real — developers trust it, fork it, and build on it publicly.”

How to defend

Double down on the MCP server as the agent-native interface and own the 'backend for AI apps' positioning hard — pgvector plus auth plus realtime is a bundle no LLM alone can replicate.

  • Expose API-key auth with a self-serve sandbox tier; remove sales-call gates (+15).

overview

What is Supabase?

Supabase is a backend-as-a-service (BaaS) platform developed by Supabase that enables developers, startups, and companies to build web, mobile, and AI applications rapidly. It provides a comprehensive suite of open-source tools including a PostgreSQL database, authentication, file storage, and real-time capabilities. Positioned as an open-source alternative to Firebase, Supabase leverages enterprise-grade open-source technologies to offer a fully managed PostgreSQL database, instant APIs, and serverless Edge Functions. The platform integrates pgvector for storing and querying high-dimensional vector data, making it suitable for modern AI and machine learning applications. Supabase maintains a strong commitment to data security and privacy, evidenced by its ISO/IEC 27001:2022 certification and SOC2 Type 2 compliance, and explicitly states it never trains on user data.

features

Key Features of Supabase

Supabase provides a robust set of backend services designed to accelerate application development, all built around a PostgreSQL database.

  • PostgreSQL Database: A fully managed, production-ready PostgreSQL database supporting complex queries and strong data integrity.
  • Authentication: Built-in user management with support for email/password, OAuth providers (e.g., Google, GitHub), multi-factor authentication (MFA), and phone OTP, leveraging PostgreSQL's Row-Level Security (RLS).
  • Instant APIs: Automatically generates RESTful and GraphQL APIs directly from the database schema, streamlining data access.
  • Realtime Subscriptions: Enables real-time data synchronization via WebSockets, facilitating live features like chat and collaborative tools.
  • Storage: A secure and scalable object storage solution for managing files such as images and documents, with access controls integrated with RLS.
  • Edge Functions: Serverless functions written in TypeScript/JavaScript (using Deno runtime) deployed globally for low-latency custom backend logic.
  • pgvector for Embeddings: Native support for the pgvector PostgreSQL extension, enabling storage and querying of high-dimensional vector data for AI and machine learning applications.

use cases

Who Should Use Supabase?

Supabase is designed for developers, startups, and companies seeking a comprehensive, scalable, and open-source backend solution for various application types.

  • Developers: Building web and mobile applications that require real-time features, secure authentication, and a robust relational database.
  • Startups and SaaS Platforms: Requiring rapid backend deployment, scalable infrastructure, and role-based access control for their services.

pricing

Supabase Pricing & Plans

Supabase operates on a freemium model, offering a free tier with limited resources suitable for small projects and experimentation. Paid plans, including Pro, Team, and Enterprise, provide increased resources, dedicated support, and enhanced backup retention policies. The Pro plan, starting at $25 per month, includes 7 days of daily backups. Team plan projects offer 14 days of backups, and Enterprise plan projects retain up to 30 days of backups. Business Associate Agreements (BAA) are available upon request for Team and Enterprise customers, supporting HIPAA alignment.

  • Free Plan: Limited resources, suitable for personal projects and testing, projects paused after one week of inactivity.
  • Pro Plan: Starts at $25/month, includes increased compute, storage, and 7 days of daily backups.
  • Team Plan: Custom pricing, designed for collaborative teams, includes 14 days of daily backups and BAA availability.

Similar Tools

Supabase vs Competitors

Supabase differentiates itself within the backend-as-a-service market by offering an open-source, PostgreSQL-centric approach compared to various alternatives.

1
Appwrite↗

Appwrite is an open-source, self-hosted backend-as-a-service platform that provides core APIs for web, mobile, and Flutter developers.

Like Supabase, Appwrite offers a comprehensive suite of backend services including database, authentication, storage, and functions. However, Appwrite emphasizes self-hosting with Docker and offers a different underlying database approach (MariaDB/Postgres/Mongo via adapters), while Supabase is built on PostgreSQL.

2
Nhost↗

Nhost is an open-source GraphQL backend that combines PostgreSQL, Hasura, and serverless functions to provide a GraphQL-native developer experience.

Nhost is very similar to Supabase in its open-source, PostgreSQL-centric approach and 'Firebase alternative' positioning. The key difference lies in Nhost's strong GraphQL-first focus via Hasura, whereas Supabase primarily offers REST and its own client libraries, though it also has a GraphQL API.

3
Firebase (Google Firebase)↗

Firebase is Google's comprehensive mobile and web application development platform, offering a wide range of integrated backend services with a strong focus on real-time capabilities and a NoSQL database.

Supabase is explicitly an 'open-source Firebase alternative.' Firebase provides a broader ecosystem of tools and primarily uses NoSQL databases (Firestore and Realtime Database), while Supabase offers an open-source, PostgreSQL-based SQL approach.

4
AWS Amplify↗

AWS Amplify is a set of tools and services from Amazon Web Services designed to simplify building scalable full-stack applications, deeply integrated with the AWS ecosystem.

While not open-source in the same way as Supabase's core, Amplify provides a similar developer experience for building backends with features like authentication, data, and storage. However, it is tightly coupled with AWS services and infrastructure, often defaulting to DynamoDB (NoSQL) for data, unlike Supabase's PostgreSQL focus.
