TYW Launcher

  • Cold start you barely notice

    Local cache plus async loading. The window shows up first, data arrives later. No splash animation, no spinner.

  • Four platforms, one model

    Versions, accounts and download sources stay separate per platform, but the structure is the same.

  • Extension system

    Java, Python and Node.js, plus native binaries built with C / C++ / Go / Rust / Zig.

  • Bedrock in the same version list

    Bedrock and Java editions share one list and one launch button.

  • Three release channels

    Stable, snapshot for early features, beta for verification. Beta keys are issued per device and can be revoked.

  • Open source

    All code lives on GitHub. Issues, ideas and pull requests are welcome.

What it is ​

TYW Launcher (codename TML) is an open-source Minecraft launcher. It manages versions, accounts, downloads and launching. No social feed, no store, no ads.

  • Never patches the game — everything happens at the launch-argument level.
  • No forced login — offline mode works on its own.
  • No locked server — no address is compiled in. Official builds inject one via environment variable or server.txt; open-source builds are offline by default.

Three-minute start ​

  1. Download the package for your platform (stable / snapshot / beta).
  2. Open it and pick a data directory.
  3. Sign in (Microsoft or offline).
  4. Pick a Java runtime and click "Download game".
  5. Click "Launch game".

See Install; signing in, picking Java and downloading the game are covered section by section in Features.
