I helped out one of my friends that ran a spring break coding camp for middle school girls where we used Cloud9 back when it was free (pre-aquisition at least). We had easy access to chromebooks, so it made sense, especially since you could have a teacher account where you could set up accounts for students. They have a similar teacher mode today, but getting it set up looks more involved, and I'm not sure what the features and pricing are.<p>I wonder who the main users are. Schools certainly make sense with the notoriously locked down computers.<p>There appears to be more free competitors now, so I'm curious what we'd use today. Eclipse Theia looks like VSCode, so that'd probably the most appealing to a lot of teams like mine. Eclipse Che/Codeenvy looks like the most popular. There's a lot more low-key options for sure. Has anyone tried Github Codespaces?
