GDLauncher vs MultiMC

MultiMC pioneered multi-instance Minecraft launching, though its last official release was 0.6.14 in December 2021 and most active development has moved to its forks (Prism Launcher chief among them). GDLauncher is a modern, opinionated launcher with deep automation. Here's the practical comparison.

Feature GDLauncher MultiMC
CurseForge support Yes No
Modrinth support Yes Yes
Auto Java management Yes No
Auto mod updates Yes No
Auto modpack updates Yes No
Multi-instance Yes Yes (its specialty)
Cloud Instance Sharing Yes (one-click code, mixed CF + MR) No (manual export, no mixed CF + MR)
Server management Yes (built-in) No
Modern UI Yes No
Pays addon authors Yes No
Source on GitHub Yes Yes
Lightweight No Yes (very)

Automation vs control

MultiMC's design is "do nothing the user didn't ask for." That means you set the Java path, you pick the version, you manage mods, you update them. Power users love this. New players bounce.

GDLauncher takes the opposite approach: detect what each instance needs, install it, keep it updated, but expose all the same knobs in instance settings if you want to override anything. The defaults work; the controls are still there.

Modpack handling

MultiMC has a built-in Modrinth browser, but no CurseForge integration. To play CurseForge packs you'd need to import them manually as zip files, or use third-party tools to fetch the manifest. GDLauncher's browser shows CurseForge and Modrinth side by side, with one-click installs on both.

The legacy

MultiMC hasn't shipped a new release since December 2021; the project's energy has effectively moved into Prism Launcher and other forks. If you've used MultiMC for years and want a more modern UI without losing the workflow, Prism is the natural upgrade path; GDLauncher is the bigger jump (more automation, fewer manual steps). Try both and pick the model that fits how you actually use a launcher.

Cloud Instance Sharing

Sharing a setup with a friend in MultiMC means exporting the instance to a zip and handing the file over. That works, but it's a file you have to host somewhere, and the recipient has to import it the same way. GDLauncher's Cloud Instance Sharing replaces that with a short code: paste it, the launcher pulls the snapshot from the GDL service, and mods re-download from their original CDNs. One code, mixed CurseForge + Modrinth content in the same share, no zip file to pass around.

The verdict

MultiMC is a great choice if you want a tiny, hyper-flexible launcher and are happy doing your own Java setup, mod management, and updates. GDLauncher is for players who'd rather have those things handled automatically, auto Java, auto updates, one-click installs, Cloud Instance Sharing, and server management, without sacrificing the multi-instance workflow MultiMC pioneered.
