We built https://boxes.dev specifically for cloud dev / isolated VMs (disclosure, I'm one of the founders). Getting work off your laptop is such a productivity boost when you have parallel threads. Obviously there are a ton of products in this category (rest of the comments here have many examples) but we're 100% focused on the cloud experience
Trying this out... based on Claude's assessment it's got the fullest support for my existing workflow requirements compared to some of the others ones suggested.
