Launcher 1.1.0 · Mod 1.2.0 · supports Minecraft 26.1.x

The launcher that
doesn't waste your frames.

Veltrix is a native Windows launcher — no Electron, no web wrapper. It cold-starts in about a second, launches every Minecraft version from 2010 alphas to 26.1.1, and ships a 25-module client mod you can extend with plain JavaScript.

Launcher

Everything a launcher should do. Nothing it shouldn't.

Built after studying what people actually complain about in Lunar's and Feather's launchers: slow startups, mods that reinstall themselves, missing Linux-era versions. Veltrix keeps it native and keeps you in control.

Every version, one click

The full Mojang manifest — releases, snapshots, betas, alphas — including the new 26.1.x era. Install with live progress, launch with verified assets.

Auto mod sections

Install a version and it gets its own mod profile automatically. Browse Modrinth in-app, drag-and-drop jars, duplicate and switch profiles freely.

One-click FPS pack

Sodium, Lithium, FerriteCore, ImmediatelyFast, Krypton and friends — matched to your game version with per-mod toggles. No bundled client forced on you.

👤

Real Microsoft sign-in

Device-code flow through Xbox Live and XSTS, multiple accounts, instant switching. Tokens stay encrypted on your machine with Windows DPAPI.

🧍

Skin library

3D-rendered skin previews you can drag to rotate, PNG upload, classic/slim, and a trick nobody else has: grab any player's skin by typing their name.

Java handled for you

Veltrix detects which Java each Minecraft version needs — 8, 17, 21, 25 — and silently downloads a matching Temurin runtime if you don't have one.

The Veltrix mod

A client mod that respects the server rules.

Press Right Shift in game and you get a searchable menu of 25 modules — every one of them display-only or quality-of-life. No reach hacks, no auto-clickers, nothing that gets you banned.

  • Feather-style menu — type to filter, scroll the list, every module has an icon, a toggle and a ⚙ cog with real settings.
  • Minimap with terrain colors, height shading, a rotating player cursor and live dots for players and mobs.
  • Motion blur that follows your camera speed — strength slider included (26.1.x).
  • Drag-and-drop HUD editor: place any module anywhere, scroll to resize, fully transparent background so you see the real game.
  • Cosmetics — six capes, four hats — equip them in the launcher or in game and both stay in sync live.

Module builder

Don't see the module you want? Write it. In JavaScript.

The mod embeds a sandboxed JavaScript engine. Drop a .js file in the scripts folder, hit Right ShiftReload Scripts, and your module is live — no compiler, no restart, no Java.

config/veltrix/scripts/hello.js
// a custom HUD card + a chat command
veltrix.hud("Hello", function () {
    return ["Hi " + veltrix.getName(),
            veltrix.getFps() + " fps"];
});

veltrix.command("hello", function (args) {
    veltrix.chat("Hello from my own module!");
});
  • HUD cards from a single function — draggable and resizable in the HUD editor like any built-in module.
  • Events: tick, chat, join — react to the game as it happens.
  • Local .commands — messages starting with a dot never reach the server.
  • Game data getters: position, health, FPS, ping, biome, held item, time of day and more.
  • Sandboxed — scripts can't touch files, network or Java. A crashing script disables itself, never the game.
