I've been using repl.it for a couple of (or more, I suppose) years now, and it's been very helpful to have a simple, reliable REPL to jump into, test things out, and to share code. I've turned students and colleagues to it, too. I'm excited to see where you're taking it. I hope it continues to load and run quickly.
Just wanted to say thanks for building it, and keep up the great work!
Yes we aim for 2 seconds loadtime irrespective of the environment (we maybe a bit of the mark in some cases but not too far off) and part of the post was about reassuring folks like you that although it will increase in power it doesn't mean that it will be slower or more complex.
