WP-KiwiIRC is a WordPress plugin which will allow you to easily embed a KiwiIRC client into your website’s posts or pages.
WP-KiwiIRC is available on GitHub at https://github.com/xnite/wp-kiwiirc

Download WP-KiwiIRC

Please send all bug reports & feature requests to the issue tracker on the project’s GitHub.
If your issue is with the client itself and not the WordPress plugin, used to embed the client, then please direct your bug report over to the KiwiIRC project, not me. I am in no way affiliated with the KiwiIRC project or application.

Example:
