Features
Every instance,
its own lane
Download once, then stack vanilla, modded, and modpack worlds side by side — separate folders, separate Java, separate drama.

Modpack management
One-click modpack lanes
Pick Modrinth or CurseForge, install into a dedicated instance, and let Prism match loader plus Minecraft version before the first launch.
Mod management
Mods without folder surgery
Browse Modrinth or CurseForge from inside an instance. Install, update, or remove jars locally — neighboring setups never feel it.
Instance management
Stacked layers per instance
Clone, rename, or archive whole stacks without touching siblings in your library.
Java / runtime
Java tuned per pack
Assign the JDK each instance needs, set heap for heavy modpacks, and park JVM flags next to that world — not in one fragile global slot.
Themes & UI
Color your launcher
Spectrum-friendly Qt themes and icon packs — personalize the shell without changing how instances boot.
