Earlier today our friends at Digicoop released Kaiwa, a great new text chat app for the web with a super-friendly user experience. We’re keen on the fact it's built on top of some of the open source code we’ve been working on for years, such as the Stanza.io library for XMPP in JavaScript.
Yeti Lance Stout created a prototype application called Otalk.im along these lines a while back (as demonstrated at RealtimeConf 2013 starting around 16:45), and through the beauty of open source software the Digicoop team forked that code as the foundation for Kaiwa.
Congratulations, Digicoop!
