Minecraft is a video game developed by Mojang. A “launcher” is a program that lets players choose the game version, check news, and start the game.

A few years ago, I created a Minecraft launcher in Java based on a tutorial. Over time, it became outdated and incompatible with newer Java versions. I therefore decided to develop a new one in C#, both as a personal challenge and to take advantage of modern libraries.

The goal was to build a custom launcher capable of running a specific version of Minecraft, including additional files such as resource packs and configuration settings. I set up a web server to host and verify the integrity of these files using hashes, integrated the Discord API to display in-game status, and used Microsoft and Mojang APIs for user authentication.

The project also includes a “bootstrap” executable that automatically handles launcher updates. The administrator can easily adjust various settings through an online configuration file (API keys, Discord messages, logo, etc.) without requiring technical knowledge.
