Custom extensions, API integrations, and seamless embedding into your system landscape.
Standard software often covers 90% – we close the last gap. We develop Pipelines, connect Open WebUI with your tools, and automate workflows.
From API integration to complete custom solutions – we cover the entire spectrum.
We make your systems talk to each other. Whether REST, GraphQL, or webhooks – we connect software with your CRM, ERP, or identity provider.
Often data formats from System A don't match System B. We develop middleware that sits in between, transforms data, and controls processes.
Want to use software features in your own intranet or customer portal? We embed software headlessly and build custom UIs around it.
Save manual work through intelligent automation. We develop bots and scripts that handle tasks automatically.
Open WebUI brings chat interface and RAG pipeline – but enterprise requirements demand more. We extend the frontend for your use cases.
We use the REST API for integrations and pipelines for custom model routing: The appropriate model is automatically selected based on input.
Input and output filters: Before sending to the model we can enrich prompts (RAG context), after the response we can perform compliance checks.
For UI customizations we develop custom Svelte components: Special input forms, visualizations, industry-specific chat layouts.
How we implement Open WebUI development in practice.
Different requests (code vs. text vs. analysis) need different models, but users shouldn't have to worry about it.
Pipeline that analyzes input and automatically routes to the optimal model (GPT-4, Claude, local Llama) – transparent to the user.
Internal documents (SharePoint, Confluence) should be searchable in chat without manually uploading them.
Automatic sync of enterprise documents into vector DB. With every question, relevant context from the knowledge base is injected.
LLM responses could contain sensitive info (PII, internal codes). Must filter before display.
Output pipeline that scans responses and masks or blocks sensitive data before displaying to user.
Update-safe, scalable, and secure – why you should trust us with your development.
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.
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.
We use modern, type-safe technologies: React, TypeScript, Node.js, Python, Go. Plus PostgreSQL, Redis, and Docker/Kubernetes for infrastructure.
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
From requirements to go-live – transparent and structured.
We review API documentation, analyze your requirements, and identify optimal integration points.
We design the solution: middleware, plugin, or script. Data flows, interfaces, and security concept are defined.
Agile implementation with code reviews, automated tests, and continuous coordination. You see progress in real-time.
Integration into your CI/CD pipeline or hosting on our infrastructure. Documentation and training included.
Let's get technical. We'll assess feasibility and effort.
