Seppuku Client is a free, lightweight, open-source Minecraft Forge client-side mod for Minecraft 1.12.2

Originally oriented towards 9B9T and 2B2T, it is a fully-featured anarchy client mod with an external plugin API, unique exploits, and a solid community.

Currently supports all Windows/Linux/MAC based operating systems that support java 8.

! WARNING ! Breaks old configs, Simply move all files in Seppuku/Config to Seppuku/Config/Default if updating from 3.1.8 or below.

(If you do not already have a Minecraft Forge environment for modding minecraft, please create one for Minecraft 1.12.2.
There are many tutorials online on how to create one, here are a few: Minecraft Wiki, Stack Overflow, WikiHow.)

Place the "seppuku.jar" file into your mods folder.

Seppuku's default command prefix is the period character "."

Try entering a singleplayer session or multiplayer server and typing ".help" in chat.

To see a list of all the modules in Seppuku, enter the ".modules" command.

To edit an individual module, enter the module's name followed by the option to configure: ".freecam" or ".freecam speed 1"

Press ~ (GRAVE) or right shift (RSHIFT) to enable the GUI.

Inside the GUI/Hud Editor you will be greeted with a small tutorial and the Hub component.

The Hub component is a list of all the available components for you to use. Each component is enabled by left click; scroll with mouse wheel or using the scrollbar.

Drag hud components around freely, each one allows clamping onto screen corners and merging with other hud components to stack.

Middle clicking any component results in a white-border indicating it is now 'locked' or, in other words: entirely stopped from changing positions when resizing the screen.


The Tray component is centered at the bottom of the screen by default. It provides shortcuts to commonly used hud components.

Right click on an icon inside the tray to enable it's relevant component.
