- README: fix broken 'Also See' placeholder URL -> live Gitea LAN URL - index.md: expand vllmScripts See Also with the endpoints it serves - OpenWebUI.md: :7770 backend is the llama.cpp PP head (split to the 3090), managed by vllmScripts; note the FLM NPU :52625 alternative; fix the broken [[llama.cpp Server]] wikilink - Gitea.md: hosted repositories table (both projects) - Dankclaw Stack.md: host-level LLM endpoints in the service inventory - AGENTS.md: runtime note — LLM endpoints live in vllmScripts, not here Pre-existing failures (untracked ComfyUI WIP): tests 6, 8, 9, 10. Docs seams green: ok 19 (compose service docs), ok 20 (index links).

# 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 `:cuda` image 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:
|
||
|
||
```yaml
|
||
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 `:7770` endpoint is the `frank-default-large` service, managed by
|
||
> the sibling `vllmScripts` repository (not this repo). Model swaps,
|
||
> context sizing, and spec tuning happen there. See the
|
||
> [vllmScripts knowledge base](../../vllmScripts/docs/index.md).
|
||
>
|
||
> Alternative backend: `frank-default-small` on port 52625 (FastFlowLM,
|
||
> AMD NPU, `qwen3.6-moe:35b-a3b`). Same OpenAI-compatible API shape. Point
|
||
> `OPENAI_API_BASE_URL` at `http://host.containers.internal:52625/v1`.
|
||
|
||
## Volumes
|
||
|
||
| Container path | Host path (convention) |
|
||
|----------------|------------------------|
|
||
| `/app/backend/data` | `/opt/openwebui/data` |
|
||
|
||
## 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.
