FAQ
What technologies do you use?
WPF (.NET) for native Windows launchers, or Electron (JS/TS) for cross-platform Windows, macOS, and Linux. Tell me your preference, or I will recommend the best fit based on your needs and audience.
Will it support Microsoft account login?
Yes. Microsoft account authentication is included from Standard tier upwards. Mojang accounts are end-of-life and not supported by Minecraft auth servers anymore, so Microsoft auth is the only working option for legitimate launchers.
Can it download modpacks automatically?
Yes. Standard and Premium tiers include modpack download and management. Modpacks can be hosted on your own server, GitHub, or a hub backend I provide on Premium tier. Auto-update keeps players in sync when you push new mods.
What about future Minecraft updates?
Free fixes for any issues caused by bugs in my delivered code within scope. Minecraft version bumps that require new auth endpoints or new launcher manifest formats are billed as separate work — I will give a clear estimate before starting.
Do I get the source code?
Yes. Full source code is delivered, no licensing fees, no lock-in. Build instructions and a deployment guide are included so you can compile and ship updates yourself without depending on me.
