- Installation
- Run the official Docker image, install the Python package, or deploy with Kubernetes
- Operational Setup
- 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
- The Catch / Trade-off
- 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.
