Continuing the discussion from Where can i find the Hipchat logs:
While I agree it’d be ideal to have something like the chat from stackoverflow made open,
I’m not sure why not IRC. There are quite a few webchats for IRC (you probably know about mibbit and I just got to know about kiwi), and native clients are even more plenty.
As it is, I consider HipChat quite bad. Guests can only use the online version without any customization, which means either block all notifications or get 'em all, all the time. There is no log or search and there are limited features such as attaching files.
I realize it is integrated with github and codecombat’s own versioning so when you’re logged in it will notify people of what you’re doing, looks like, but I doubt that’s something that couldn’t be done within IRC.
With that being said, do you know ChatBox? I got to know it through Make Penn Bad. It’s made by this crazy dude, Phil Gordon and it looks quite promising. Since you’re going with proprietary anyway, maybe Phil can even help you there. He loves getting feedback and I think it’s all still in its early stage. At least it’s also cheaper than HipChat.
