Supabase Development

Backend-as-a-Service with PostgreSQL, Auth, Realtime and Storage

The open-source Firebase alternative

The backend that grows with your product

Supabase is the open-source alternative to Firebase — built on a technology that has proven itself for decades: PostgreSQL. Instead of locking you into proprietary NoSQL structures, you get a full-featured relational database with Row Level Security, real-time subscriptions, Auth, Storage and Edge Functions — all in one place.

The result: You can focus on your product instead of building backend infrastructure from scratch. Supabase gives you everything you need for a fast start without painting yourself into a corner. And because everything is open source, you always retain full control over your data and architecture.

We use Supabase in projects where speed and flexibility make the difference — from MVPs and SaaS platforms to internal tools and real-time applications.

Our Services

Supabase Core Services

Supabase bundles the most important backend services into a single platform. No piecing together individual solutions — everything works seamlessly together.

PostgreSQL Database & Row Level Security

The full power of PostgreSQL — including Joins, Views, Stored Procedures and extensions like PostGIS or pgvector. Row Level Security ensures that access rules are defined directly in the database, not in the application layer.

Authentication & User Management

Email/password, Magic Links, OAuth providers (Google, GitHub, Apple etc.) and SAML SSO — all out of the box. Multi-Factor Authentication and fine-grained session management included. No third-party provider needed.

Realtime Subscriptions

Supabase streams database changes to your frontend in real time. Whether chat, dashboards or collaborative editing — Realtime Subscriptions are based on PostgreSQL Logical Replication and work without a dedicated WebSocket server.

Storage & Edge Functions

Upload, transform and deliver files — with built-in policies for access control. Edge Functions based on Deno enable server-side logic right at the edge, without running your own server.

Deployment & Operations

Whether managed in the cloud or self-hosted on your own infrastructure — Supabase gives you the choice. We help you find the right setup for your project.

Supabase Cloud (Managed Hosting)

The fastest path to production. Supabase Cloud handles hosting, updates, backups and scaling. You get a dashboard, a CLI and API access — the platform takes care of the rest.

Self-Hosted / On-Premise

Supabase can be fully deployed on your own infrastructure — Docker, Kubernetes or bare metal. Ideal for companies with strict data protection requirements or regulatory obligations in the DACH region.

Database Migrations & Branching

With the Supabase CLI, you manage schema changes as code. Database Branching enables isolated development environments per feature branch — database development becomes as agile as your code.

Monitoring & Backups

Automatic point-in-time backups, database metrics, query performance monitoring and alerting. We set up the infrastructure so you can sleep soundly at night.

Why Supabase with Medienstürmer

Open Source & No Vendor Lock-in

Supabase is fully open source (Apache 2.0). Your data lives in a standard PostgreSQL database that you can migrate at any time. No proprietary format, no platform dependency — you stay in control.

PostgreSQL Power

Instead of a limited NoSQL database, you get the full power of PostgreSQL: Joins, Views, Foreign Keys, Stored Procedures, Triggers, Extensions. The query language is SQL — no proprietary query format you need to learn first.

Rapid Development

From idea to working prototype in days instead of weeks. Auto-generated APIs, built-in Auth, real-time features and a convenient dashboard dramatically accelerate development — without sacrificing quality.

Strengths and Limitations of Supabase

Strengths

Open source with Apache 2.0 license — no vendor lock-in, full transparency
PostgreSQL as the foundation — proven, powerful and universally applicable
Built-in Auth, Realtime, Storage and Edge Functions from a single platform
Row Level Security directly in the database — security at the database level
Self-hosting possible — full data sovereignty for regulated industries
Fast project start with auto-generated REST and GraphQL APIs

Good to know

Relatively young platform — some features are still in Beta or Early Access
Smaller community than Firebase — fewer third-party tutorials and plugins
Edge Functions are based on Deno — more limited runtime environment than a full backend
Complex server-side business logic requires additional backend services
With Supabase Cloud, dependency on the provider for hosting and SLA
Realtime performance at very high throughput requires careful architecture

The right tool for the right job

Supabase is not a silver bullet — but for many use cases, it is the smartest choice. We use Supabase where it can fully leverage its strengths, and combine it with custom backend services for more complex requirements when needed.

When do we use Supabase?

SaaS Platforms & Web Apps

Supabase provides the complete backend for multi-tenant SaaS products: user authentication, role-based access control via Row Level Security, real-time updates and file storage. You start fast and scale when the time comes.

MVPs & Prototypes

When speed matters, Supabase is ideal. Auto-generated APIs, built-in Auth and a convenient dashboard enable functional prototypes in days — without a backend team and without infrastructure setup.

Real-Time Applications

Chat systems, collaborative tools, live dashboards or notification systems: Supabase Realtime streams database changes directly to connected clients — without having to set up your own WebSocket server.

Internal Tools & Admin Panels

For internal business tools, you often need fast CRUD operations, user management and file storage. Supabase delivers all of this out of the box — combined with Row Level Security for fine-grained access control.

Mobile Apps with Offline Sync

Supabase offers SDKs for Flutter, React Native and Swift. Combined with local data storage, you can build apps that work offline and automatically sync when a connection is available.

AI & Vector Applications

Thanks to the PostgreSQL extension pgvector, you can store and query vector embeddings directly in Supabase. Ideal for semantic search, RAG pipelines and AI-powered applications — without a separate vector database.

How It Works

Project Setup & Data Model

We analyze your requirements and design the database schema in PostgreSQL. Tables, relationships, indexes and Row Level Security policies are defined cleanly from the start — as SQL migrations that are versioned and reproducible.

Auth, APIs & Frontend Integration

We configure authentication with the appropriate providers, set up storage buckets and connect the frontend via the auto-generated APIs or the Supabase client. TypeScript types are generated directly from the database schema.

Edge Functions & Business Logic

We implement server-side logic as Edge Functions or — for more complex requirements — as supplementary backend services. Webhooks, cron jobs and triggers automate recurring tasks directly in the database.

Go-Live, Monitoring & Operations

We configure backups, set up monitoring and alerting, and support the go-live. After launch, we can take over ongoing maintenance, performance optimization and further development of your Supabase infrastructure.

Frequently Asked Questions about Supabase

Honest answers to the questions you are probably asking yourself.

The most important difference: Supabase is built on PostgreSQL instead of a proprietary NoSQL database. That means real Joins, Foreign Keys and SQL — no workarounds for relational data. Additionally, Supabase is fully open source and can be self-hosted. With Firebase, you are completely tied to Google Cloud.

Yes. Supabase is used in production by thousands of companies and processes billions of database queries. The core components — PostgreSQL, GoTrue (Auth), PostgREST (API) — are standalone, proven open-source projects. Some features like Branching or Queues are still in Beta, but the core platform is stable.

Yes. Supabase can be fully self-hosted — with Docker Compose or on Kubernetes. You have full control over your data and infrastructure. This is particularly relevant for companies in the DACH region with strict data protection requirements.

Supabase uses PostgreSQL Row Level Security to enforce access rules directly in the database — not in the application code. This means: Even if your API key is compromised, users can only access the data they are entitled to according to the policy. On top of that, you get JWT-based Auth, TLS encryption and SOC 2 Type II compliance on the cloud platform.

The Free Tier is sufficient for prototypes and small projects. The Pro Tier starts at 25 USD/month per project and includes daily backups, 8 GB database and 250 GB bandwidth. For enterprise requirements, there are custom plans with dedicated resources and SLA. Self-hosted is free — you only pay for your infrastructure.

In principle, yes. You can use an existing PostgreSQL database as a starting point and add Supabase features (Auth, Realtime, Storage) on top. With self-hosted setups, you have full flexibility. With Supabase Cloud, there are some limitations regarding custom extensions.

For many use cases, no. Supabase Edge Functions cover server-side logic like webhooks, email sending or payment integration. For more complex business logic, elaborate data processing pipelines or microservices architectures, we recommend supplementary backend services — for example with Node.js or Java.

We start with a free 30-minute initial consultation where we understand your project and assess whether Supabase is the right approach. After that, we work in agile, short sprints: You see results after each iteration, provide feedback and actively steer the direction. Communication via Slack or Teams, full access to the project board.
