Multiple Upload Directory Assistant - An image dumper script for imageboards

MUDA - Multiple Upload Directory Assistant (alternatively: 無駄)

Muda is a directory dumper program written for 8chan and vichan derivatives.

Given a directory, a thread, and a board, it will dutifully post all files in the specified directory automatically, leaving you free to do other things.


  • Java 8 - will not work on any previous versions, yet.

Limitations & Notes

  • DEV releases are very unstable and probably missing features. The Java version of Muda is very very new.
  • Only tested on 8chan. It should work on other vichan boards with similar URL structure.
  • Irresponsible use of this script is likely to get you banned. Some sites/boards may not want you dumping. Act accordingly.
  • For obvious reasons, muda will not work on boards with a captcha enabled.
  • Default timeouts work reasonably well for 8chan and are as low as I can get them without causing a lot of flood detections. Experiment if necessary.
  • You will obviously get more timeouts if you particpate in the thread you’re dumping into.
  • Ensure that the type of files you’re dumping are allowed on the board you want to dump on, otherwise you will get strange errors.
  • The ruby version isn’t being worked on anymore, but is still available on a separate branch.


  • Make sure Java is in your local path
  • Run the script with the help option to see full details: java -jar muda.jar -h
  • Please report any bugs here :)


Minimum required: java -jar muda.jar --thread 123456 --board b --directory /home/anon/images

Other options are available. Examine the output of -h to customize your dump.

You thought you would find information on the name here, but instead you found me, Dio!
