# Usage

The uvicorn command line tool is the easiest way to run your application...

## Command line options

```shell
Usage: uvicorn [OPTIONS] APP

Options:
--host TEXT Host
--port INTEGER Port
--loop [uvloop|asyncio] Event loop
--http [httptools|h11] HTTP Handler
--workers INTEGER Number of worker processes
--log-level [debug|info|warning|error|critical]
Log level
--help Show this message and exit.
```

Uvicorn currently includes two HTTP implementations, "httptools" and "h11".

It also supports two different event loop implementations, "uvloop" and
Python's standard "asyncio".

The default configuration is to use httptools and uvloop. If you need to
run under [PyPy][pypy], then you should switch to h11 and asyncio.

## Running programmatically

To run uvicorn directly from your application...

```python
import uvicorn

...

if __name__ == "__main__":
uvicorn.run("127.0.0.1", 5000, log_level="info")
```

## Running with Gunicorn

[Gunicorn][gunicorn] is a mature, fully featured server and process manager.

Uvicorn includes a Gunicorn worker class allowing you to run ASGI applications,
with all of Uvicorn's performance benefits, while also giving you Gunicorn's
fully-featured process management.

This allows you to increase or decrease the number of worker processes on the
fly, restart worker processes gracefully, or perform server upgrades without downtime.

For production deployments we recommend using gunicorn with the uvicorn worker class.

```
gunicorn app:App -w 4 -k uvicorn.workers.UvicornWorker
```

For a [PyPy][pypy] compatible configuration use `uvicorn.workers.UvicornH11Worker`.

# The ASGI interface

Uvicorn uses the [ASGI specification][asgi] for interacting with an application.
