Mods

Mods are packages of code and assets that provide additional content or modify existing game features. Mods are usually written in JavaScript and have access to the browser engine shapez runs in. Examples of content provided by mods include new buildings, user-adjustable settings, level sets and user interface features. Many shapez mods intend to increase or reduce difficulty of the gameplay, while some mods may allow skipping parts of regular gameplay process altogether.

In shapez (official distributions)

Mods for the official versions of shapez can be found at mod.io and are commonly distributed as loose JavaScript (.js) files or ZIP archives with additional information that may be useful to the player. Authors of mods can make use of a simple mod settings system to save game-wide settings or other persistent data; alternatively, they may provide configurability by dedicating a section of the source code with variables to be adjusted by the player.

In shapez CE

shapez CE makes use of a different mod loader that is incompatible with mods made for official versions of shapez. Mods for shapez CE are distributed as ASAR archives and may contain multiple source code, asset or data files. As of May 2026, there is no central place for distribution of shapez CE mods.
