Crazierl: an Erlang Operating System

You can join your friends in a dist cluster, by sharing a url with the
same hashtag, and enabling dist with the checkbox below the terminal.

Hashtag (for linking)

Please wait while the emulator starts. Javascript is required.

Warnings

• There is no security barrier between nodes in a dist cluster; you should
  only use dist between nodes you control and trust
• This demo uses gen_tcp_dist which communicates in plain text; you should
  only use this on a network you control and trust
• This demo uses wss://relay.widgetry.org to provide networking service;
  chances are you don’t control that.
• “no one in their right mind would run the unencrypted and
  unauthenticated Erlang distribution unsecured over the internet.” —
  jhogberg, Erlang Core Team in
  thread
• Maybe you got a link from not a friend, and you’re
  connecting to a totally random person
• If someone malicious can dist connect to your crazierl node, they can
  control it, and if there’s a v86 vm escape, they could also control your browser window
• Do not use credentials or enter sensitive information or PII
• Chatting with people on the internet can be dangerous.
• This operating system has not been modified to comply with California’s Digital Age Assurance Act
  (2025 AB 1043), and may not be suitable for use in your jurisdiction.

I understand the risk,
but let’s play dist with friends anyway

Try chat:start(). after you’re dist connected!
