Is there any webchat client with a daemon for Raspbian/Raspberry Pi? Something like webpidginz or an alternative for it. I found it hard to use with Raspberry Pi/Raspbian (because it doesn't provide an ARM version for their plugin.)
Is there any better and lightweight webchat client/BNC for Raspbian? (I don't want use irssi or a terminal based clients also).
I should think any linux chat client should work - try Pidgin (installing FAQs) or Empathy.
Performance will be an issue though, the GUI will probably be slow to respond. (I would therefore recommend Finch (essentially Pidgin for the terminal), but you've said you don't want a terminal client.
If I understood you correct; you want an always-on IRC bouncer, with web-based IRC client to connect & use.
As an IRC bouncer, I would recommend ZNC any day, it's feature-complete, uses 1mb~ of RAM most of the time, also has a very nice Web GUI for settings. Plus it's very easy to install.
I'm using it with my a desktop client (Quassel), if you want there are plenty of java-based IRC clients (I wouldn't recommend one because I didn't use any of them), pick one, upload it to your Pi and serve it from there. (using, nginx?) At the end of the day, you'll have a complete BNC server and a web-based IRC interface.
subway is migrated from MongoDB and now can be used easier on Rasbian.
I haven't try them, but you can try the following softwares.
Single user chats allow you to chat with one or more people that you have in your friend list. Some known clients are Pidgin, Gajim, or GTalk.
Some web-based examples:
MUC are clients allowing you to join different rooms and chat with people you don't necessary know. A well known MUC client is IRC (not XMPP).
Some web-based examples:
If you manage to install one of them, please share your experience by asking and answering a new question.
