Mods/Datapacks

A Minecraft mod is a mod that changes aspects of the sandbox game Minecraft. Minecraft mods can add additional content to the game, make tweaks to specific features, and optimize performance. Thousands of mods for the game have been created, with some mods even generating an income for their authors. While Mojang Studios does not provide an API for modding, community tools exist to help developers create and distribute mods. The popularity of Minecraft mods has been credited for helping Minecraft become one of the best-selling video games of all time. As of March 2025 there are more than 257,308 Mods for Minecraft across different mod hosting sites such as Curseforge, Modrinth, and PlanetMinecraft.

The first Minecraft mods worked by decompiling and modifying the Java source code of the game. The original version of the game, now called Minecraft: Java Edition, is still modded this way, but with more advanced tools. Minecraft: Bedrock Edition, a version of the game available for mobile, consoles, and Microsoft Windows, is written in C++, and as a result cannot be modded the same way. Instead, modders must use "add-ons" written in a scripting language to add content.
