Whird
Whird is web software for creating websites.
I am writing and developing Whird for my own needs, but I have released it for free under the GNU General Public License. It can be downloaded here.
Some installation instructions exist for the brave. Also, you might want to see some basic system requirements and/or read a feature list. If you are interested in the development of Whird, you can branch the code and browse the development logs.
Warning!
Whird is currently very rough around the edges and should definitely not be considered for use on any production websites. Whird comes with ABSOLUTELY NO WARRANTY, to the extent permitted by applicable law.
Also, Whird has limited documentation, apart from the included README and a few notes on this site. I plan on fixing this when I get time.
Owners club
Despite the above warning, some brave souls have decided to give Whird a whirl. For the sake of posterity, I thought it might be a nice idea to record their endeavours.
