Slingcode is a personal computing platform in a single html file.

• You can make, run, and share web apps with it.
• You don’t need any complicated tools to use it, just a web browser. You don’t need a server, hosting, or an SSL certificate to run the web apps.
• You can put Slingcode on a web site, run it from a USB stick, laptop, or phone, and it doesn’t need an internet connection to work.
• You can “add to home screen” in your phone’s browser to easily access your library of programs on the go.
• You can share apps peer-to-peer over WebTorrent.
• It’s private. You only share what you choose
