One mod.
Infinite modules.
Mosaic is a free, open-source cosmetics mod for Minecraft. Build your experience from individual modules — or, as a developer, code your own.
No sign-up · No ads · No pay-to-win mechanics
Features
Everything a mod needs — nothing it doesn't.
Mosaic brings the essentials and lets you assemble the rest yourself.
Free & Open Source
Fully open source under a permissive license. No account, no paywall, no ads — just install and play.
Modular System
Enable only what you need. Every feature is its own module — cleanly separated, individually toggleable and light on resources.
Cosmetics
Capes, wings, hats, auras and more — purely visual and fair. No pay-to-win, just a way to express your style.
Developer API
A clear, documented API. Write your own module, hook into events and share it with the community.
Performance
Built to be lightweight. Modules run asynchronously where possible and won't drag down your FPS.
Community-driven
By the community, for the community. Contributions, issues and pull requests are always welcome.
Modules
Cosmetics & more
Every module can be toggled on its own. Mix freely — your game, your style.
Capes
Animated & static capes
Wings
Wings with gentle motion
Hats
Head accessories & crowns
Auras
Particle effects around the player
Emotes
Gestures & animations
Nametags
Customizable name tags
For developers
Code your own module.
The Mosaic API is intentionally small. Register a module, hook into the events you care about — done. No boilerplate, no hidden magic.
- Clear, documented interfaces
- Hot-reload in development mode
- Share your module with the community
// A custom cosmetic module in a few lines
public class GlowModule extends Module {
@Override
public void onEnable() {
registerCosmetic("aura.glow");
events.on(RenderPlayerEvent, this::render);
}
private void render(RenderPlayerEvent e) {
// Draw a soft glow around the player
Mosaic.fx().glow(e.player(), 0xFFFFFF);
}
}Open Source
Transparent from the very first line.
The entire source is public. Audit it, improve it, fork it — or just open an issue. Mosaic belongs to the community.
