## Running Guillotina on another ASGI server

Guillotina supports the following ASGI ([Asynchronous Server Gateway Interface](https://asgi.readthedocs.io/en/latest/index.html "Link to ASGI spec."))
servers out-of-the-box:

- [Uvicorn](https://www.uvicorn.org/ "Link to Uvicorn") (used by default)
- [Hypercorn](https://pgjones.gitlab.io/hypercorn/ "Link to Hypercorn")

Use the argument `--asgi-server` to choose one of the previous servers:

```shell
guillotina serve -c config.yaml --asgi-server=hypercorn
```

You can use any other ASGI server by using `guillotina.entrypoint:app` as the app and the environment variable `G_CONFIG_FILE` to specify the configuration file.

### Example

Running Guillotina on Hypercorn with [QUIC](https://en.wikipedia.org/wiki/QUIC "Link to QUIC") support:

```shell
G_CONFIG_FILE=config.yaml hypercorn --quic-bind 127.0.0.1:4433 guillotina.entrypoint:app
```
