# Open WebUI
|
|
|
|
[Open WebUI](https://github.com/open-webui/open-webui) is a user-friendly WebUI for LLMs. It supports various LLM runners, including [[ollama]] and OpenAI-compatible APIs.
|
|
|
|
{#start}
|
|
## Getting Started
|
|
|
|
```nix
|
|
# In `perSystem.process-compose.<name>`
|
|
{
|
|
services.open-webui."open-webui1".enable = true;
|
|
}
|
|
```
|
|
|
|
## Examples
|
|
|
|
{#ollama}
|
|
### Open WebUI with ollama backend
|
|
|
|
```nix
|
|
{
|
|
services = {
|
|
# Backend service to perform inference on LLM models
|
|
ollama."ollama1" = {
|
|
enable = true;
|
|
# The models are usually huge, downloading them in every project directory can lead to a lot of duplication
|
|
dataDir = "$HOME/.services-flake/ollama1";
|
|
models = [ "llama2-uncensored" ];
|
|
};
|
|
# Get ChatGPT like UI, but open-source, with Open WebUI
|
|
open-webui."open-webui1" = {
|
|
enable = true;
|
|
environment =
|
|
let
|
|
inherit (pc.config.services.ollama.ollama1) host port;
|
|
in
|
|
{
|
|
OLLAMA_API_BASE_URL = "http://${host}:${toString port}";
|
|
WEBUI_AUTH = "False";
|
|
};
|
|
};
|
|
};
|
|
# Start the Open WebUI service after the Ollama service has finished initializing and loading the models
|
|
settings.processes.open-webui1.depends_on.ollama1-models.condition = "process_completed_successfully";
|
|
}
|
|
```
|
|
|
|
See [[ollama]] for more customisation of the backend.
|
|
|
|
{#browser}
|
|
## Open browser on startup
|
|
|
|
```nix
|
|
{
|
|
services.open-webui."open-webui1".enable = true;
|
|
# Open the browser after the Open WebUI service has started
|
|
settings.processes.open-browser = {
|
|
command =
|
|
let
|
|
inherit (pc.config.services.open-webui.open-webui1) host port;
|
|
opener = if pkgs.stdenv.isDarwin then "open" else lib.getExe' pkgs.xdg-utils "xdg-open";
|
|
url = "http://${host}:${toString port}";
|
|
in
|
|
"${opener} ${url}";
|
|
depends_on.open-webui1.condition = "process_healthy";
|
|
};
|
|
}
|
|
```
