Cilla is a weblog written in Java.
See the online documentation. There is also a set up guide.
The idea behind Cilla was just a "quick Java blog hack" that should replace my PHP based blog. However, this quick hack soon became a huge project that took me several years to make it what you see today.
The blog itself is feature complete and stable. I use it for my personal weblog since 2010.
The administration GUI is usable, but it misses some non-essential functions and also contains a few annoying bugs. Cilla also needs a nice installer (or maybe a Docker image), a choice of themes, and some in-depth documentation.
Cilla is sufficient for me in its current state, so I am not going to put much more time into it in the near future. However, I hope that this project might be useful to other people. If you want to improve Cilla, I really appreciate your help!
