I've used Repl.it ever since it became publicly available and I've used it to teach some classes and camps. As a college student, it's also a great environment to quickly open a coding scratchpad to do the occasional LeetCode problem and share my solution with others.
In the past, I've used cloud IDEs like Cloud9 and CodeAnywhere, mainly because I worked on the school computers in high school. But other than that, I don't know why a regular dev or even a college student might use this. Although one usecase may be easily-usable special-purpose programming environments for higher-level college courses that might otherwise require a ton of local setup. And the tight integration with Github might actually make sense for that setting.
For me "spinning up the entire environment" comes to clicking the icon of whatever IDE I decide to run for whatever task I am about to do. Is it such a big trouble?
I understand that it has good value for teaching to the point until students have to accomplish something more serious then some glorified "Hello World".
As for access from anywhere - I can access my development workstations remotely from anywhere with no problems (thanks to NoMAchine ond/or RDP) but since I also lug my super duper laptop anywhere I rarely need to enable this kind of access.
But then again I am a cloud luddite. I own all my computing/development resources (well I rent some remote dedicated servers for backup/standby purposes). Other people have different attitude which is fine. I just hate the idea of my stuff residing/being controlled by any other entity but myself.
I still use Repl.it if I want to try out something in a hurry, or especially if I want to post a code sample for one of my Stack Overflow answers.
Both of these options are great! It's not one vs. another.
I do not perceive those as mutually exclusive. Both are good but for a different things. It does seem to me however that anything not cloud/web based is becoming anathema in some circles.
It supports popular languages, works fully in a browser so nothing to install and you can co lab with multiple people.
aka hacking on an app, like people who read Hacker News might do.
a lot of people, including replit engineers + designers (like myself) :)
If people can build apps on Google Forms + IFTT/Zapier or on Bubble.is etc then an entire programming environment plus database seems like it should be enough to build things on too.
So many of these threads feel like a team of "social media workers" are manipulating it.
In most threads, HN hates centralization, loves privacy and loves personal control. In ad related threads, they love centralization, have no care for privacy and love giving up more control.
They've just added some key-value db support and they call it the best place to build your app?
Unix+Vscode+asdf = I can pretty much use that stack to build anything, change my mind...
Edit: and it's just basic stuff that you're gonna use when you code professionally, so why not start with it anyway
