I don't seem to be in the right communities to randomly encounter Glitch often, but from my tinkering it's a pretty neat environment to quickly build casual (maybe the wrong term, but that's how it feels - in a positive way) apps with real code. While they can/do host apps directly, it's been hard to tell just how far you can take such an app load-wise, so this news seems to open up the ability to use Glitch as an IDE of sorts but scale your creations further, so.. cool.
