Hi everyone! I'm Murad, the creator of NIB, a visual game editor and engine I've been building over the past several months. NIB 1.0.0, the first stable release, is now available for making 2D and 3D games.
Download the stable engine · Stable 1.0.0 release on GitHub
The trailer shows actual gameplay and editor footage captured from the distributed 1.0.0 release:
From a scene to a playable game
Build a scene visually, add JavaScript gameplay, test in Play mode, and export a game people can run in their browser. The Hierarchy and Inspector let you organize entities, components, prefabs, models, sprites, cameras, and lights.
Worlds and rendering: WebGL2/WebGPU, materials, terrain sculpting and painting, foliage, and prop scattering.
Characters and animation: sprite frame animation, skeleton and skin-weight editing, keyframes, blending, animation state graphs, and retargeting maps.
Effects: reusable particle, geometry, trail, light, and audio layers, triggered by scripts or animation events.
Gameplay systems: built-in 2D physics, bundled Rapier 3D, baked grid navigation, editable menus/HUDs, input actions, and spatial audio.
Testing and export: Play/Stop, Console and Profiler, Single HTML or Web Project ZIP export; an optional packager wraps a Single HTML game as a portable Windows x64 application.

Start by changing something
The stable release includes ten playable starter games, six rendering/animation showcases, and empty 2D/3D scenes. Try an FPS, racer, platformer, or physics workshop: inspect its scene and scripts, make a change, and export your own variation.

Optional local MCP workflow
The included local MCP server exposes 62 tools for inspecting projects, editing scenes and scripts, managing assets/effects, testing, capturing screenshots, and exporting. Connect a compatible client separately; an AI service or subscription is not bundled. You can also work directly in the visual editor.
A recent game made with NIB: Two Thrones
I've also been using the engine to build Two Thrones, a Heroes of Might and Magic III-inspired turn-based strategy game with a 3D overworld, two factions, town building, army recruitment, seven spells, and hex battles. The world, terrain, vegetation, lighting, and export use NIB; the strategy rules are authored as game logic.

See the game's development log and more screenshots. This is a separate showcase project, not included in the NIB 1.0.0 download. It uses AI-assisted artwork, models, music, and sound effects, described in the devlog.
Free for personal and commercial games
NIB's engine/editor is proprietary and free to use for personal, educational, and commercial games, with no mandatory subscription or royalties. Your original game code and assets remain yours. See the license and preserve the required runtime and third-party notices when distributing games.
Getting started: the compiled editor runs locally with Node.js 22.12+ and a desktop Chromium browser. Extract NIB-1.0.0.zip, run start.bat on Windows or sh start.sh on macOS/Linux, and follow the included guide. Players of hosted web exports do not need NIB or Node.js.
I'd appreciate feedback from developers trying the editor: what felt clear, where did you get stuck, and what would help you finish a small game? If you have a few minutes, try a starter game, change something, and export it. You can reply here, ask questions in GitHub Discussions, or report a reproducible bug in GitHub Issues.
