Crystal Launcher is an alternative and unofficial Minecraft launcher with a built‑in modpack repository.
It lets you run any official Minecraft release (from rd‑132211 up through Minecraft 26.3) and install mods easily—thanks to the integrated Forge and Fabric mod loaders.
It also includes an automatic installer for Technic, CurseForge, Modrinth, FTB and ATLauncher modpacks—why juggle multiple launchers when you only need one? 😊
