Puter is an operating system that runs inside a web browser.
Does that really qualify as an "operating system"?
Yes, it's a full OS you just access remotely through your browser.
You don't "access it through your browser" though, right? Based on how I understood the concept it's just ("just") Javascript running in your browser.
I mean, it's a neat project, but I'm still not convinced it qualifies as an operating system
Well an operating system is a system that ... operates, so even if I made one with one of those lego-block scripting languages it would qualify right?
I don't know, but I would have thought that the key task of the OS is to provide an abstraction that allows apps to run on supported hardware. So it takes care of file access and creation, outputing to the screen, interacting with external devices such as keyboards, webcams etc.
If you already have a browser running, you already have some kind of OS taking care of those low level details.
So a docker container isn't running an os?
Depends on the container, but yeah, there might not be an os at all.
So basically your browser (or main OS maybe) is just a hypervisor for this.
With that logic everything is an operating system
Honest question, why does anyone need this? You are presumably already on an OS in order to use this.
2 main reasons.

Using cloud environments is a pretty cheap and easy way to do data prevention loss, which is what corpos call it when they implement measures to prevent data from getting leaked. If you store all the data in this and gate this behind 2fa, then getting the main device hacked leaks no data provided the "cloud os" is logged out.

Chromebook users. Docs suck, onlyoffice web sucks less.
Similar: anuraos, https://github.com/MercuryWorkshop/anuraOS
Anuraos is special because it uses a js linux emulator to execute linux apps. Very, very slowly. But it's there and there is even gui support.
