Interior Design Software — Free Room Designer Online

Interior Design That Runs in Your Browser

Aedifex is a free interior design tool that works on any device with a modern browser. Start with an empty room or import your floor plan, then furnish, style, and visualize your space in real-time 3D.

Who It's For

  • Homeowners redecorating or moving into a new place, figuring out what fits where.
  • Interior designers doing quick concept sketches for clients before committing to full 3D software.
  • Stagers and decorators needing visuals for proposals.

Design Workflow

1. Start with a Room

Draw walls or import a floor plan. Set room dimensions, ceiling height, and choose wall/floor materials from the built-in library.

2. Place Furniture

Drag from the furniture catalog: living room sets, bedroom suites, kitchen islands, desks, shelving. Every piece is a real 3D model with accurate dimensions. Scale, rotate, or snap-align with one click.

3. Apply Materials

Swap wood, stone, fabric, paint, wallpaper on any surface. See the material change instantly under realistic lighting. Try 10 options in 10 seconds without committing.

4. Preview Lighting

The 3D view uses physically-based rendering with real-time shadows. Move the sun angle to see how morning vs evening light falls through your windows.

5. Share the Result

Generate a shareable link. Clients or family can open the design in their browser and walk through the space. No special software on their end.

Why Browser-First

Desktop interior design tools (SketchUp, Chief Architect, 3ds Max) have steep learning curves and hardware demands. Aedifex aims for the 80% of use cases where you want to try ideas fast, share easily, and not worry about file versions.

What to Test Before Buying

Use the interior design workflow to test the decisions that are expensive to fix later: sofa size, bed placement, rug scale, cabinet color, flooring tone, curtain clearance, and lighting direction. A room can look good in a mood board and still fail when the door hits a chair or the window glare lands on a desk.

Because the scene is interactive, you can evaluate the design from standing height, not only from a top-down plan. Walk through the room, compare material options, and share the link before ordering furniture or finishes.

Built for Fast Iteration

Aedifex is not trying to replace specialist rendering software for final luxury visuals. It is built for the earlier stage where speed matters: try ten layouts, reject seven, refine two, and share one clear direction with the people involved.
