Hi,

I want to create my own IM and I'm searching an open-source IM APIs. What do you think is the best open-source IM APIs. And what good front end to use?

Thanks.

XMPP... lots of documentation, libraries and so on. http://xmpp.org

I believe XMPP is just an IM protocol. Jabber is an implementation of the XMPP protocol.

Nope. XMPP used to be named "Jabber", and some documents still mention the old name. Now it is assumed that if you talk about "Jabber", you talk about the old pre-XMPP-1.0 version of the protocol.

If you are looking into making a client, check out libpurple. This is what pidgin and many other IM clients use to access multiple IM networks.

If you are just worried about one IM network, the easiest one to work with would be Jabber because it is an open sourced protocol

If you're interested in the OSCAR protocol (AIM), check out Open AIM. They have documentation on custom clients for C++/C#/Java as well as how to access Web AIM.

If you need server side to support IM, use OpenSIPS. For client side, pidgin and libPurple.

Just to be comprehensive, telepathy is a rather good competitor to libpurple. It's secure, modular and robust.

You can use QXmpp. It is a free (LGPL) XMPP client library written in C++ and Qt. It's light and simple to use.
