CloudBot is a simple, fast, expandable open-source Python IRC Bot!
CloudBot is currently unmaintained. The project possibly usable, but there are currently no developers building new features or fixing bugs.
There are several forks of CloudBot which you may want to use instead. These projects have much more work done on them, and are thus incompatible. If you already have a running CloudBot instance you will probably need to start over from scratch.
