A custom backend can quickly grow into an expensive and risky infrastructure
When you develop a backend from scratch, you have to handle authentication, user authorization, backups, database security, file storage, and protection under heavy load. A single mistake in the API or access rules can expose sensitive data, cause a system outage, and create a GDPR issue.
Data leaks
Improperly secured API endpoints can expose data to unauthorized users.
High costs
Managing servers, databases, backups, and monitoring can quickly inflate the project budget.
Slow synchronization
Real-time notifications, chats, or live dashboards can easily stretch into weeks of work on a custom backend.
Row Level Security (RLS)
Data access is verified directly in the database according to rules and the logged-in user.
Real-time via WebSockets
Supabase automatically broadcasts database changes to connected clients. Ideal for order tracking, chats, and live dashboards.
Edge Functions & Serverless
Custom TypeScript functions can handle payments, webhooks, and integration logic without a separate server.
Robust custom backends
A secure infrastructure built on open technologies.Modern backend infrastructure without compromises
Supabase accelerates web and mobile application development by combining database, authentication, storage, real-time communication, and serverless functions into one backend foundation. Because it runs on PostgreSQL, it suits applications that need relational data, clear access rules, and solid database control. Supabase also supports backups, monitoring, and scaling as traffic grows.
Key features of the Supabase platform
How we design a Supabase backend
PostgreSQL relational
schema design
We define tables, indexes, and relationships so the database can handle real-world loads.
RLS rules
configuration
We set up SQL rules that determine data access based on the user and their permissions.
Auth & SSO
integration
We configure login via Google, Apple, email, or corporate SSO.
Edge Functions
integration
We write secure APIs for payments, webhooks, and external service integrations.
Supabase vs. Firebase vs. custom Node.js backend
When Supabase is not the ideal choice for you
Supabase is built on PostgreSQL. If your project needs to store massive amounts of unstructured data without relational links—such as sensor data or high-volume logs—a NoSQL or specialized analytical database might be more appropriate. Supabase also requires a strong knowledge of SQL and RLS rules. Improperly configured permissions can cause security issues.

[email protected]Supabase can be designed for cloud or self-hosted deployment depending on project requirements. For European cloud projects, we select an EU data center, typically Frankfurt. For self-hosting, Supabase is deployed via Docker on infrastructure you own or have contractually secured with providers such as Hetzner, Netcup, Scaleway, AWS, Google Cloud, or Microsoft Azure. Data transfer is encrypted, and database access is protected through Row Level Security, firewalls, backups, monitoring, and proper permission settings. The result is a backend with clear technical and contractual control, designed around GDPR requirements.
Yes. Supabase is open-source and can run on your own infrastructure via Docker. However, with self-hosting, you must account for managing the database, backups, updates, monitoring, and security. For some projects, the cloud version makes more sense, while for others, a custom infrastructure in the EU is better.
In a standard backend, the API often checks whether a user can see a specific record. In Supabase, the database itself can perform this check via RLS rules. If configured correctly, users only receive the rows they are authorized to see based on their login token.
Yes. We use Supabase Edge Functions for this. Upon a successful payment, Stripe sends a webhook to an Edge Function, which verifies the request signature and securely writes the payment information into the PostgreSQL database.
