Supabase Development & Integration
Custom extensions, API integrations, and seamless embedding into your system landscape.
Standard software often covers 90% – we close the last gap. We develop Edge Functions, connect Supabase with your tools, and automate workflows.
Our Development Services
From API integration to complete custom solutions – we cover the entire spectrum.
API & Interface Integration
We make your systems talk to each other. Whether REST, GraphQL, or webhooks – we connect software with your CRM, ERP, or identity provider.
- Bidirectional data synchronization
- Third-party system connections
- Custom webhooks & event handlers
- Legacy system integrations
Custom Middleware & Logic
Often data formats from System A don't match System B. We develop middleware that sits in between, transforms data, and controls processes.
- Transformation layer (ETL)
- Data stream validation
- Caching layer for performance
- Microservices architecture
Embeddings & Custom Apps
Want to use software features in your own intranet or customer portal? We embed software headlessly and build custom UIs around it.
- White-label integration
- Custom dashboards (React/Vue)
- UI extension via plugins
- Mobile app customizations
Automation & Bots
Save manual work through intelligent automation. We develop bots and scripts that handle tasks automatically.
- ChatOps & slash commands
- Automated reporting
- Workflow orchestration
- Trigger-based actions
Postgres Superpowers & Serverless
Supabase is more than a database. It's a complete backend ecosystem. We use the full power of PostgreSQL (extensions, triggers) combined with global Edge Functions.
Edge Functions (Deno/TypeScript)
Business logic doesn't belong in the client. We develop performant Edge Functions for payment processing (Stripe), PDF generation, or AI inference, running securely and close to the user.
Database Triggers & Webhooks
We make your database reactive. A new user registers? A trigger automatically creates profiles, sends welcome emails via webhook, or updates statistics – atomic and transaction-safe.
Postgres Extensions & RLS
Security starts in the database. We design complex Row Level Security (RLS) policies ensuring User A never sees User B's data. We also leverage extensions like pgvector for AI search.
Concrete Use Cases
How we implement Supabase development in practice.
Multi-Tenant SaaS Architecture
You are building a SaaS and must guarantee strict data separation between tenants without operating a separate DB for each.
Implementation of an RLS architecture based on `tenant_id`. The frontend uses the Supabase client, the DB filters automatically. 100% secure, 0% leaking risk.
Realtime Collaboration Features
Users should see who is currently working on the same document (cursor tracking, live edits), like in Google Docs.
Using the Supabase Realtime API (Broadcast & Presence). We synchronize state between clients in milliseconds without having to operate our own WebSocket servers.
Vector Search & Embeddings
Standard text search delivers poor results. Users want semantic search ('documents about climate change' instead of keyword match).
Integration of `pgvector`. We store embeddings of your data directly in Postgres and enable ultra-fast similarity search via Edge Functions.
Development with Foresight
Update-safe, scalable, and secure – why you should trust us with your development.
Update-safe (No Core Hacking)
We don't modify the open-source software's source code. Instead, we use official APIs and plugin architectures. Your installation remains updatable and maintainable.
Full-Stack Expertise
We understand not just the code, but the infrastructure beneath it. Our developers know how queries affect database performance and how to build scalable APIs.
Modern Tech Stack
We use modern, type-safe technologies: React, TypeScript, Node.js, Python, Go. Plus PostgreSQL, Redis, and Docker/Kubernetes for infrastructure.
Security by Design
Every line of code is written with security in mind. Input sanitization, secure authentication (OAuth2/OIDC), and compliance with data protection regulations are standard.
Our Tech Stack
How We Work
From requirements to go-live – transparent and structured.
Analysis
We review API documentation, analyze your requirements, and identify optimal integration points.
Architecture
We design the solution: middleware, plugin, or script. Data flows, interfaces, and security concept are defined.
Development
Agile implementation with code reviews, automated tests, and continuous coordination. You see progress in real-time.
Deployment
Integration into your CI/CD pipeline or hosting on our infrastructure. Documentation and training included.
