CurseForge is the official modding platform and launcher built for Minecraft Java Edition, deeply integrated with the CurseForge mod repository. It provides one-click modpack installation, automatic dependency management, and seamless updates for all mods. However, it requires Overwolf, which increases RAM and CPU usage. It’s perfect for casual players who want hassle-free access to thousands of pre-made modpacks, including RLCraft, All the Mods, and SkyFactory.

Prism Launcher is a lightweight, open-source alternative based on MultiMC, designed for power users who need full control over their modding experience. It supports multi-instance management, allowing players to run different Minecraft versions with separate mod configurations, resource packs, and Java runtime settings. Unlike CurseForge, Prism Launcher doesn’t rely on Overwolf, meaning better performance, lower memory consumption, and zero background tracking. It also has native Modrinth support, enabling direct downloads from Modrinth repositories, along with manual CurseForge mod imports.
