OpenWebUI
OpenWebUI is a self-hosted chat interface for LLMs. It connects to OpenAI-compatible endpoints, Ollama, llama.cpp, and vLLM, and adds RAG, plugins, tool calling, and multi-user support.
Host: Dankclaw — Hostname: chat.dankclaw.local — Port: 3000 — Docs: https://github.com/open-webui/open-webui
Facts (from research, primary source)
| Item | Value |
|---|---|
| Image | ghcr.io/open-webui/open-webui:main (CPU build for non-NVIDIA hosts) |
| Port | 3000 (host) → 8080 (container) |
| Data volume | config, sessions, RAG indexes |
| Backend | OpenAI-compatible endpoint at http://localhost:7770/v1 — the llama.cpp PP head (Qwen3.8-27B, tensors split to the Dankserver RTX 3090 worker) |
Note: the
:cudaimage tag was previously used on Dankserver. Dankclaw is AMD; use the default (CPU) image, NOT the cuda tag.
Connecting to llama.cpp
OpenWebUI talks to the local llama.cpp server through its OpenAI-compatible API. Configure a new connection in the UI or set the base URL:
environment:
OPENAI_API_BASE_URL: "http://host.containers.internal:7770/v1"
OPENAI_API_KEY: "none"
The hostname host.containers.internal reaches the podman host where llama.cpp listens on 7770.
The
:7770endpoint is thefrank-default-largeservice, managed by the siblingvllmScriptsrepository (not this repo). Model swaps, context sizing, and spec tuning happen there. See the vllmScripts knowledge base.Alternative backend:
frank-default-smallon port 52625 (FastFlowLM, AMD NPU,qwen3.6-moe:35b-a3b). Same OpenAI-compatible API shape. PointOPENAI_API_BASE_URLathttp://host.containers.internal:52625/v1.

Healthcheck
OpenWebUI responds on /health with 200.
Gotchas
- Use the non-CUDA image on AMD hosts.
- The default admin account is created on first login; secure it immediately.
- If the backend (llama.cpp) is slow to load, OpenWebUI may show connection errors until the model is ready — that matches the known 3–8 minute model load time.
