Cactus MC Launcher vs Refract

Cactus MC Launcher is a free desktop launcher for managing Minecraft instances, modpacks, and dedicated servers on Windows, macOS, and Linux. It supports separate instances, Java runtime management, automatic updates, and a built-in modpack catalog. The launcher works with mods, resource packs, shaders, and modpacks from Modrinth and CurseForge. Available loaders include Vanilla, Fabric, Quilt, Forge, and NeoForge. Instances can be grouped by version and loader, with custom icons and cover art. Server tools include a live console, world management, ops and whitelist controls, and one-command sharing. The interface can be customized with backgrounds, gradients, decor, a movable dock, and toggleable click sounds. Cactus MC Launcher is built with Tauri and Rust, contains no ads, and does not track users. It is made by Ladvace and released under AGPL-3.0; the download page lists version 1.5.1. The project provides a GitHub link and a Discord community link. It is not an official Minecraft product and is not associated with Mojang or Microsoft.

Refract is a free launcher for organizing Minecraft modpacks on Windows, macOS, and Linux. It supports modpacks from Modrinth, CurseForge, and FTB, with a built-in catalog for finding compatible content. Multiple mod loaders are supported, and modpack import is available through both listed methods. Each pack runs in a separate instance, with its mods, resource packs, worlds, settings, and launch options kept apart. The launcher can install dependencies, update individual mods in place, manage Java runtimes, and apply automatic updates; worlds are preserved during updates. Existing libraries can be imported without mixing files or damaging saves. Users can choose themes, accent colors, sidebar layouts, Java versions, memory limits, and launch behavior. Refract is licensed under GNU GPL v3.0, and its application and website are developed in public. The project uses Tauri and Rust for its native shell. Discord supports player help and project discussions, while GitHub is used for bug reports, change proposals, and code contributions.
