I built a fun little Mac app called "Outer Loop". Download it at https://outerloop.sh

It's a specialized web browser that is aware of SSH. It's good at connecting to web apps running on private servers. Use it for Tensorboard, Jupyter, etc.

I also wrote a blog post about its internals: "Web apps over SSH can be surprisingly good" https://probablymarcus.com/blocks/2025/10/10/web-apps-over-ssh-surprisingly-good.html
