What is Numek Launcher?
Numek Launcher is a free Minecraft launcher for Windows that manages your instances, mods, resource packs, shaders and skins from a single application. It runs as one process, shows no advertising, and searches for mods across both the CurseForge and Modrinth catalogues at once.
Is Numek Launcher free?
Yes. Numek Launcher is free, ad-free, requires no account and has no paid tier. The site generates no revenue and the launcher offers no purchases.
How much memory does Numek Launcher use compared with CurseForge?
In a paired reading — both applications open on the instances list, on the same machine and at the same moment — Numek Launcher occupied 10 MB of memory and the CurseForge process group 1.9 GB. At rest, Numek Launcher holds about 10 MB, and 10 to 45 MB in use depending on the instance on screen; CurseForge settles between 400 and 600 MB at rest. The Windows task manager screenshots and the exact conditions of the reading are published on numek.fr.
Why does Numek Launcher use so little memory?
Numek Launcher is a native single-process application with no embedded browser, where CurseForge starts seven to fifteen processes. A few seconds after opening, Numek Launcher hands back to the system the memory pages its startup called for and no longer uses, instead of waiting for Windows to reclaim them. It does so again when its window steps aside during a game, so that memory goes to Minecraft instead.
Which mod loaders does Numek Launcher support?
Numek Launcher supports six loaders: Vanilla, Fabric, Quilt, Forge, NeoForge and Cleanroom, the last one for Minecraft 1.12.2. The chosen loader is downloaded and installed by the launcher, with no separate installer to run.
Do I need to install Java to use Numek Launcher?
No. Numek Launcher downloads the Java version each Minecraft version calls for and uses it for that instance. You have nothing to install and nothing to choose.
Can I use my existing CurseForge instances in Numek Launcher?
Yes. Numek Launcher detects CurseForge's instances folder and shows those instances beside its own, playable without moving or copying anything. They stay managed by CurseForge: renaming and deleting them is still done from its application.
Does Numek Launcher install modpacks?
Yes. Numek Launcher searches for modpacks on CurseForge and Modrinth, and installs each one as a new instance with its Minecraft version, loader and mods. When a mod's author forbids downloads by third-party launchers, the instance is created anyway and the launcher points out the files to fetch by hand.
Does Numek Launcher show my activity on Discord?
Yes, when Discord is open, and a single setting turns it off. In game, Numek Launcher shows the Minecraft version, the loader and the number of mods; in the launcher, the number of instances. The names of your instances are never published.
How do I uninstall Numek Launcher?
From Windows settings, under “Installed apps”, like any other application. Your instances, settings and accounts are kept apart from the program: uninstalling does not delete them.
Which systems does Numek Launcher run on?
Numek Launcher runs on Windows. macOS and Linux builds are planned: session token encryption needs adapting there, and that work is not done yet.
Does Numek Launcher collect personal data?
No. Numek Launcher transmits no usage statistics and builds no machine identifier. It reaches only the servers it needs to do its work: the game's and the Microsoft account's, the CurseForge and Modrinth catalogues, the mod loaders' own, the skin sources, and GitHub, where its updates come from. Microsoft session tokens are encrypted by the operating system and tied to your Windows account. The numek.fr site sets no cookies, except the one that remembers your language if you change it; it counts visits with Vercel Web Analytics, anonymously and in aggregate, with no stored identifier.
Why does Windows show a warning when installing Numek Launcher?
The installer is not signed with a commercial certificate, so SmartScreen reports “Windows protected your PC” on first launch. Select “More info”, then “Run anyway”. Installation happens inside your user folder and asks for no administrator rights.
Is Numek Launcher affiliated with Mojang, Microsoft or CurseForge?
No. Numek Launcher is affiliated with neither Mojang, Microsoft nor Overwolf. Minecraft is a trademark of Mojang Synergies AB, CurseForge a trademark of Overwolf Ltd. and Modrinth a trademark of Rinth, Inc. These names are cited for identification and comparison.
Where can I download Numek Launcher?
Numek Launcher is downloaded from numek.fr, which always redirects to the Windows installer of the latest published release. Earlier releases and their notes are listed at numek.fr/versions.
