Deep Dive: Switching from Admix to Open WebUI
Trade-offs, installation & data architecture
What you trade away
Parallel chats work, but the self-hosted interface is less focused on clean side-by-side evaluation and still leaves provider setup and billing to you.
How to deploy Open WebUI
Run the official Docker image, install the Python package, or deploy with Kubernetes
What it takes to run
A non-expert must install Docker or a compatible Python environment, mount persistent storage correctly, and separately provide Ollama or an API endpoint
Where your data lives
By default, chats and account data live in a local SQLite webui.db, uploads in a data/uploads directory and embeddings in the configured vector store; PostgreSQL and object storage are optional
Why fork Open WebUI instead of vibe-coding a Admix clone?
A local chat UI with side-by-side replies is a weekend project when it calls OpenRouter, but Admix's value depends on access to many hosted models, a current catalog, provider routing, and a maintained account and billing layer. You can reproduce the comparison workflow. You cannot reproduce the model access and service layer for a flat $10 subscription.
