NIB 1.0.0 released — free visual 2D & 3D game editor with JavaScript and HTML export

[MooradXO]

Hi everyone! I am Murad, founder of ProjectAI and creator of NIB, a visual 2D & 3D game editor and engine. NIB 1.0.0, the first stable release, is now available.

Make a world. Give it rules. Let someone play.

For HTML5 developers, the workflow is straightforward: assemble a scene, write JavaScript gameplay, test it in the editor and export a playable browser game as a Single HTML file or a Web Project ZIP.

What is included

• A visual scene editor for entities, components, models, sprites and prefabs.
• JavaScript gameplay with editable Inspector parameters.
• Character rigs, keyframe animation and animation states.
• Layered effects, PBR materials, terrain and audio tools.
• 10 playable starter games in the stable 1.0.0 download.
• An optional local MCP server with 62 tools for compatible clients.

NIB is free for personal, educational and commercial games, with no mandatory subscription or royalties. The engine/editor is proprietary; your original game code and assets remain yours.

If you would like to try it, open a starter preset, make one small change and export your own version. I would love to see what you build and hear where the editor needs improvement.

A newer example: Two Thrones, a turn-based strategy game made with NIB. This is a separate newer project and is not included in the stable 1.0.0 archive.

NIB 1.0.1 is available as a stable maintenance update. For HTML5 developers, the main changes are more reliable Single HTML export (preserving script/text strings), RGB/RGBA hex color support, runtime HDR asset loading, and WebGL2/WebGPU rendering/resource cleanup fixes. The update also addresses project saving, Undo/Redo, animation and physics issues: 40 confirmed fixes in total, with unchanged project and asset formats.

Back up your projects and extract 1.0.1 separately, then check save/reopen and your exported game. Corrected rendering or physics can affect projects that relied on earlier bugs. The original trailer/screenshots here show 1.0.0; Two Thrones remains a separate example outside this archive.

If you test a browser export, please include the browser and graphics backend with any reproducible issue. Thanks!
