There's also koding.com, which has been around for a while. I tried the service quite a long time ago because I used to find the "cloud coding" concept enticing, though it was definitely not as baked (probably due to Monaco not existing at the time, and likewise, browsers not being as good.) Nowadays I still feel like the user experience problems, limitations, and cost (when not subsidized) with coding this way largely make it a niche for people who have unusual needs. Especially because, there are tons of local options for reproducible dev environments, and they can continue to work without a network connection or on unreliable connections, something that is unimpressive even in the best conditions I've seen so far.
If you happen to have the exact set of needs that one of these products solve, then it can probably work fairly well. But, even when working on "web" stuff, I always find myself feeling like they're just never quite as good as just doing things locally. I feel like devcontainers and cloud coding in general are more impressive to those who haven't managed to tame their own dev environments and are seeing a solution to this for the first time.
It's also clearly useful for people on iPads and other devices that are either too low end to run/compile your code or arbitrarily limited to prevent it. However, with how powerful iPads are nowadays, it feels like if Apple ever allowed apps to use virtualization extensions, it would probably be a better solution for a lot of people who do not need a huge cloud workstation with a lot of RAM. I imagine your average Rails app or Go backend would just have no problem running directly on an iPad.
