Online Floor Plan Designer — Free, No Install

Design Floor Plans in the Browser

Aedifex is a free floor plan designer that runs entirely in your web browser. No installation, no sign-up required to try. Draw walls, place doors and windows, add furniture, and see your layout in 3D the moment you make a change.

Who It's For

  • Homeowners planning a renovation or new build who want to visualize layouts before hiring an architect.
  • Interior designers who need a quick tool for client presentations without switching away from the browser.
  • Real estate professionals who want to mock up property layouts for listings or staging proposals.

What You Can Do

Draw Walls with Exact Measurements

Click to place wall endpoints. Aedifex snaps to a grid you control (10cm, 50cm, 1m), and shows wall length inline as you draw. Curved walls are supported for alcoves and organic shapes.

Place Doors, Windows, and Openings

Drag door and window templates onto walls. Adjust width, height, and swing direction with numeric inputs. Openings automatically cut the wall and render in 3D.

Furnish and Decorate

Pick from a built-in catalog of common furniture: sofas, beds, tables, chairs, kitchen fixtures. Every item can be rotated, resized, and color-adjusted. Drop materials (wood, marble, parquet, wallpaper) onto any surface.

See Your Plan in 3D, Instantly

Switch between 2D top-down and 3D perspective views. The 3D view uses WebGPU for realistic lighting and shadows. No rendering wait times, no cloud processing.

Share with a Link

Every project gets a unique URL. Make it public and anyone can open the plan in their browser, rotate the 3D view, and walk through the space. No account required on the viewer side.

Why a Browser-Based Tool

Traditional floor plan software requires a multi-gigabyte install, a license, and often a powerful workstation. Aedifex runs on any modern browser, on any device with a GPU. Your work saves to the cloud (if you sign up) or stays in your browser (if you don't).
