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.
