Lainchan - A fork of vichan


Lainchan is a fork of vichan, a great imageboard package, actively building on it and adding a lot of features and other improvements.


  1. PHP >= 5.4 (we still try to keep compatibility with php 5.3 as much as possible) PHP 7.0 is explicitly supported.
  2. MySQL/MariaDB server
  3. mbstring
  4. PHP GD
  5. PHP PDO

We try to make sure lainchan is compatible with all major web servers and operating systems. lainchan does not include an Apache .htaccess file nor does it need one.


  1. MySQL/MariaDB server >= 5.5.3
  2. ImageMagick (command-line ImageMagick or GraphicsMagick preferred).
  3. APC (Alternative PHP Cache), XCache or Memcached


You can contribute to lainchan by:

  • Developing patches/improvements/translations and using GitHub to submit pull requests
  • Providing feedback and suggestions
  • Writing/editing documentation

If you need help developing a patch, please join our IRC channel. @ #thecage


  1. Download and extract lainchan to your web directory or get the latest development version with:

    git clone git://
  2. Navigate to install.php in your web browser and follow the prompts.

  3. lainchan should now be installed. Log in to mod.php with the default username and password combination: admin / password.

Please remember to change the administrator account password.

See also: Configuration Basics.


To upgrade from any version of Tinyboard or vichan:

Either run git pull to update your files, if you used git, or backup your inc/instance-config.php, replace all your files in place (don't remove boards etc.), then put inc/instance-config.php back and finally run install.php.

To migrate from a Kusaba X board, use


If you find a bug, please report it.

If you need assistance with installing, configuring, or using lainchan, you may find support from a variety of sources:

  • If you're unsure about how to enable or configure certain features, make sure you have read the comments in inc/config.php.
  • You can join lainchan's IRC channel for support #lainchan

Tinyboard support

vichan, and by extension lainchan, is based on a Tinyboard, so both engines have very much in common. These links may be helpful for you as well:

  • Tinyboard documentation can be found here.

CLI tools

There are a few command line interface tools, based on Tinyboard-Tools. These need to be launched from a Unix shell account (SSH, or something). They are located in a tools/ directory.

You actually don't need these tools for your imageboard functioning, they are aimed at the power users. You won't be able to run these from shared hosting accounts (i.e. all free web servers).


Wanting to have lainchan in your language? You can contribute your translations to vichan at this URL:


lainchan makes use of wPaint for oekaki. After you pull the repository, however, you will need to download wPaint separately using git's submodule feature. Use the following commands:

git submodule init
git submodule update

To enable oekaki, add all the scripts listed in js/wpaint.js to your instance-config.php.

WebM support

Read inc/lib/webm/ for information about enabling webm.

lainchan API

lainchan provides by default a 4chan-compatible JSON API, just like vichan. For documentation on this, see: .
