I built my own web tmux type thing running on a beefy metal box (for rust builds) that I access over tailscale. I was using HAPI, but I wanted to simplify and use rust for the back end and my own elm-like front-end to improve performance. I haven't published it since it's pretty specific to my workflow (I ruthlessly keep it as simple as possible), but you can think of it like a Herdr type thing in the browser. It also has a phone interface and I generally use speech instead of typing as a lot of my compositions can be stream of thought.

I use an MBA and an iPhone, but a cheap tablet or phone would work just as well. I care about network, portability, screen size + quality, and speech to text. Pretty much nothing else matters, CPU / GPU irrelevant as long as it can run a browser. I might build a native non-browser version at some point for better resource management on the client, but it hasn't been an issue so far. I would love a pair of glasses I could render text on with speech to text. It's such a gap in the market, might just build my own bespoke thing if I can source the components for it. An e-ink tablet would also be a great option for working outdoors...

Have you run into any situations where you couldn't reach back to your server? I still have an m3 macbook pro w 64gb ram that I use for local qwen when my internet isn't great ie getting stuff done on a plane. Not sure if I'd feel a loss going to MBA and having a 24gb ram max or if it would be good for me to disconnect and just read a book instead
