The original
MultiMC
An alternative Minecraft launcher for managing multiple cleanly separated instances with their own mods and saves.
Replacements
Listings that take over the same core job as MultiMC.
Prism Launcher
A Minecraft launcher that keeps every modpack in its own instance so one update cannot break the others.
Prism Launcher keeps the separate-instance model and adds built-in mod and modpack installs from Modrinth and CurseForge plus multiple account support, under GPL-3.0.
Modrinth App
The official launcher for Modrinth, built around installing mods and modpacks in a couple of clicks.
Modrinth App builds the Modrinth catalogue into the launcher, uses Rust and Tauri for a small quick app, and keeps instances separate, but CurseForge packs need manual import.
ATLauncher
A Minecraft launcher that browses, installs and manages modpacks and separate game instances.
ATLauncher focuses on browsing and installing ready-made modpacks from several sources and manages each pack's Java version, though it is less polished for building packs by hand.
GDLauncher
A free Minecraft launcher that installs mods and modpacks from CurseForge and Modrinth with one click.
GDLauncher adds one-click CurseForge and Modrinth installs and Forge, Fabric, NeoForge and Quilt support, but its published source license is not stated.
Minecraft Launcher
The official launcher for installing, updating and playing Minecraft Java and Bedrock editions and other Mojang games.
Minecraft Launcher is the official closed-source launcher that also runs Bedrock edition and snapshots, but lacks separate modded instances and mod installation.
Similar software
