spark
Emergency web server
For those occasions when your webserver is down and you want to display a quick maintainance note. Or just want to quickly demo a static site. Or whatever :)
It can take a directory, a file or directly the body string. The -proxy flag can be useful when used as a development server.
❯ spark -h
