Free AI Room Design Generator (No Login) - Before After Video - Showcase Project

AI room design tools are everywhere now, but most of them stop at one thing: Upload a room photo → generate another room photo. I wanted to build something slightly different. Instead of only showing a redesigned image, I wanted users to see the transformation as a short before-and-after video. That idea became RoomFacelift. 👉 https://roomfacelift.com What RoomFacelift does The workflow is simple: 1. Upload a photo of your room 2. Choose the room type 3. Pick an interior design style 4. Decide how much of the room can change 5. Generate a redesigned version 6. Turn the original and redesigned images into a transformation video The goal is to make AI room design feel less like generating a random image and more like visualizing an actual renovation. Keeping the original room recognizable One of the hardest problems was not image generation itself. It was preservation. AI models often change things users do not want changed: camera angle windows doors TVs wall geometry visible floor area room proportions For a room redesign tool, that can make the result feel fake. So I added two design modes. Keep Layout This mode tries to preserve: viewpoint camera height framing perspective room geometry major architectural elements The AI mainly changes furniture, materials, lighting, decoration, and interior style. Reimagine Space This mode gives the model more freedom to redesign the room while still trying to keep the same camera position and overall identity. That distinction turned out to be important because different users want very different levels of transformation. Interior styles RoomFacelift currently supports styles such as: Modern Scandinavian Japandi Mid-century Modern Industrial Bohemian Luxury French Country Minimalist Art Deco Coastal Farmhouse Mediterranean Contemporary Traditional Instead of relying only on the style name, each style is backed by a more structured design recipe. That helps make the generated results more consistent. The technical stack The application is built with: Next.js TypeScript Supabase fal.ai Cloud storage Google Cloud Run FFmpeg Waffo for payments The basic generation pipeline looks like this: text User photo ↓ Private storage ↓ AI redesigned image ↓ Before + After frames ↓ Image-to-video generation ↓ Watermark processing ↓ Final transformation video
