The same game.
A fraction of the memory.
Numek Launcher manages your Minecraft instances, mods, packs and shaders from a single application, with no advertising and without spawning background processes.
Comparison
Resource usage
Readings taken in real use, with both applications open on the instances page. The exact conditions are published.
* Highest value recorded during use, summing every process in the CurseForge group. At rest, usage falls back into the range shown above.
As a CurseForge user, I have seen the application exceed 1.5 GB of memory. It settles around 400 to 600 MB at rest, but its usage climbs as you navigate the interface and only falls back slowly. Numek Launcher's does not move: moving between pages does not increase it.
Features
What Numek Launcher offers
Isolated instances
Each instance has its own version, mod loader and files. Shared libraries are pooled, avoiding repeated downloads of the same gigabytes.
Two catalogues, one search
Mods, resource packs, data packs and shaders, searched across CurseForge and Modrinth in one place, installed into the instance of your choice.
Microsoft accounts
Official device-code authentication. The code is copied to the clipboard as soon as the page opens, with no manual entry.
Built-in updates
The launcher checks for new versions on startup, downloads only the difference in the background, and applies it on the next restart.
Mod version tracking
Every mod shows its installed version and reports when a newer one exists for your Minecraft version, with updating reduced to a single action.
Integrated logs
Game output is captured inside the application, filterable and exportable. No console window opens in the background.
Security
How your data is handled
Tokens encrypted at rest
Microsoft session tokens are encrypted by the operating system and tied to your Windows account. They are never written to disk in the clear.
Checksums verified
Every downloaded file is checked against the SHA-1 hash published by the catalogue. A file whose hash does not match is rejected and not installed.
No telemetry
The launcher communicates only with Mojang, CurseForge and Modrinth servers. No usage statistics are transmitted.
Confined writes
Filenames coming from a remote catalogue are validated before writing, and no file can be written outside its own instance folder.

macOS and Linux builds are planned. Token encryption will need adapting there; that work is not done yet.
Windows warning on first launch
The installer is not signed with a commercial certificate, so SmartScreen will report « Windows protected your PC ». Select « More info », then « Run anyway ». This warning disappears as the download count grows.
