Modpack management

Install modpacks from Modrinth, CurseForge, and FTB. Refract keeps every pack in its own clean instance and preserves worlds during updates.

Download & update mods

Find the mod you need without leaving the launcher. Browse compatible content, install dependencies, and update individual mods in place.

Minecraft instance management

Each instance has separate mods, resource packs, worlds, settings, and launch options. Import existing libraries without mixing files or breaking saves.

Lightweight & customizable

Refract uses Tauri and Rust for a small native shell. Choose themes, accent colors, sidebar layouts, Java versions, memory limits, and launch behavior.
