I need a browser-based application that lets me build complete modular kitchens in real time. The tool must load quickly in any modern desktop or mobile browser and give me these key capabilities: • 3D modeling of ready-made cabinet, countertop and accessory modules that I can drag, resize, snap and arrange on screen. • A structured, searchable library so I can save, tag and reuse every module, finish and fitting. • The option to import an actual photo or floor-plan of a customer’s site and turn it into a navigable 3D scene for precise layout work. • Immersive previews: one-tap AR on mobile (ARKit/ARCore) to place the design in the client’s real kitchen, plus WebXR-compatible VR mode for headset walk-throughs. For the front end, WebGL with Three.js or Babylon.js is ideal, but I’m open to other proven stacks if performance remains fluid. Back-end services can run on Node, Python or a comparable framework as long as the project files, module metadata and user accounts stay secure and scalable. Deliverables: 1. Fully functional web app with responsive UI. 2. Core module library populated with common Indian and international standard sizes. 3. AR and VR integrations tested on at least one recent Android, iOS and Oculus/Meta device. 4. Documentation covering setup, module-creation workflow and API endpoints. 5. Source code in a private Git repo and a short hand-off session. If any off-the-shelf engines or open-source components can shorten the timeline, feel free to propose them—license terms must permit commercial use.
