# broadwayd(1)

Broadway display server

## NAME

broadwayd - Broadway display server

## SYNOPSIS

**broadwayd** \[--port *PORT*\] \[--address *ADDRESS*\] \[--unixsocket *ADDRESS*\] \[*:DISPLAY*\]

## DESCRIPTION

**broadwayd** is a display server for the Broadway GDK backend. It allows multiple GTK+ applications to display their windows in the same web browser, by connecting to broadwayd.

When using broadwayd, specify the display number to use, prefixed with a colon, similar to X. The default display number is 0.

```
broadwayd :5
```

Then point your web browser at http://127.0.0.1:8085. Start your applications like this:

```
GDK_BACKEND=broadway BROADWAY_DISPLAY=:5 gtk3-demo
```

You can add password protection for your session by creating a file in $XDG\_CONFIG\_HOME/broadway.passwd or $HOME/.config/broadway.passwd with a [crypt(3)](/crypt/3.md) style password hash. A simple way to generate it is with openssl:

```
openssl passwd -1  > ~/.config/broadway.passwd
```

## OPTIONS

- \--port

  Use *PORT* as the HTTP port, instead of the default 8080 + (*DISPLAY* - 1).

- \--address

  Use *ADDRESS* as the HTTP address, instead of the default http://127.0.0.1:*PORT*.

- \--unixsocket

  Use *ADDRESS* as the unix domain socket address. This option overrides --address and --port. It is available only on Unix-like systems.
