OpenYotsuba is a project that aims to create a 4chan-like imageboard. It was forked from the April 2025 4chan source code leak. It is designed to be used on PHP 8.4, but it may work on other PHP versions. ***WARNING:*** OpenYotsuba is in PRE-ALPHA. Do ***NOT*** use this on a production website, it's full of bugs. How to install: 1. Move "config" somewhere safe that won't get leaked 2. Set your MySQL credentials in config/config_db.php 3. Create salts for secure tripcodes and admin stuff then store those salts somewhere safe 4. Set your global configuration in config/global_config.ini, remember to provide the paths to the aforementioned salts 5. Rename example.config.ini on config/boards to .config.ini, then set your board-specific settings 6. Set the correct path to the config directory in board/lib/ini.php, board/setup.php and board/lib/db.php 7. Rename the "board" directory to what you want your directory name to be, for example if you want "/b/" rename it to "b" 8. Go to setup.php and enter your admin credentials 9. Go to admin.php, log in and click "Rebuild All" Setting the board list (this also turns board titles to "/directory/ - Board Title"): To add a new board to the board list, log into the MySQL server, then run the following command: insert into boardlist (dir, name) values "directory", "Board Title"; Admin panel: You can access your board's admin panel by going to admin.php. CAPTCHA support: CAPTCHA support is currently disabled as I can't test it. However, if you want to try to get it working, uncomment "require_once 'lib/captcha.php'" from imgboard.php.
