Open-source mobile-first voxel survival sandbox with procedural worlds, crafting, configurable shaders, offline PWA support, and an Android launcher.
Important
BlockRealm is an original voxel sandbox project. It is not affiliated with, endorsed by, or distributed by Mojang Studios or Microsoft. Minecraft is a trademark of Microsoft.
BlockRealm is an open-source voxel game built with JavaScript and WebGL. It combines deterministic procedural terrain, survival progression, crafting, configurable shaders, offline-first PWA support, and an Android launcher in a mobile-focused package.
It is designed as a browser-based survival sandbox and procedurally generated block world that can run on phones, desktops, and compatible Android WebViews.
- Deterministic seed-based procedural worlds
- Streamed voxel chunks with biomes, caves, ores, water, and vegetation
- Nine-slot hotbar and 36-slot survival inventory
- Crafting tables, furnaces, smelting, tools, durability, health, hunger, and oxygen
- Mobile-first touch controls plus desktop keyboard and mouse controls
- Configurable shader modes, including compatibility, reimagined, and cinematic presets
- Offline standalone HTML and installable PWA builds
- Android Studio launcher project
- Original open-source voxel survival game foundation
| Platform | Status | Notes |
|---|---|---|
| Modern desktop browsers | Supported | WebGL-capable browser required |
| Android mobile browsers | Supported | Landscape orientation recommended |
| Installable PWA | Supported | Requires HTTPS or localhost |
| Android APK | Experimental | Rebuild and physical-device testing recommended |
The browser/PWA build has been confirmed to render on a Realme 13 Pro+ 5G. The earlier APK wrapper showed a black screen because the packaged launcher did not match the maintainable Android source project. The bundled APK is therefore marked experimental until it is rebuilt through Android Studio or CI and physically tested.

BlockRealm supports multiple graphics modes so users can balance quality and performance:
- Compatibility mode
- Reimagined shader mode
- Cinematic shader mode
- Shader-disabled mode
The renderer includes directional lighting, fog, animated water, day/night transitions, torch lighting, and optional atmosphere effects.
