Wakaba and Kareha

Wakaba and Kareha are my attempts at implementing from scratch image and message boards of a type popular in Japan (used on sites such as 2chan and 2ch). This kind of board software is built around anonymous posting and no requirements for registration, to make the boards more suited for casual uses, and more fun overall. They are written in Perl, and are designed to be more efficient and cleanly written than the original scripts that are available, while preserving the same kind of functionality. Both scripts are in use at iichan, an English-language site built along the same lines as the Japanese 2chan, and also 4-ch, an English-language discussion BBS.


Wakaba is an image board script very strictly modelled after the Futaba and Futallaby scripts. Wakaba borrows quite a bit of HTML code and translated text from Futallaby.


Kareha is a message board script. It is more loosely modelled after the sort of message board scripts used on 2ch and many other similar sites. It tries to use modern structured XHTML and CSS layout. It does not need a database backend either. Shii, who has his own similar message board software written in PHP, has written a nice summary about what's so good about this style of message board (mirrored here as he has pretty much given up on the project).

I used to have a script called Wakaba Zero, which was an implementation of Wakaba that did not require a database, but Kareha has now gained enough functionality to take over this role. Those who want to run an image board but do not want to bother with databases can use Kareha to run a Wakaba-like board.

Anti-spam tools for image boards

I have created a database of spammed URLs, which can be used to prevent these URLs from being posted on an image board you run. This works with Wakaba, Futaba and Futallaby, and possibly other Futaba derivatives too.

The Society for the Study of Modern Image Board Culture

This is a message board for the discussion of image boards in general, be they English, Japanese, or of any other nationality. Posting in English is preferred but not required.

And then?

I'm still working on both the code for the scripts, and also this site. There is now a documentation wiki, which contains a bit of information about the scripts. Contribution on that is welcome. There is also the support board where you can ask for help if you need it, or just discuss the scripts.
