Show HN: 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.

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