Best free floor plan software (2026)
What "free" really gets you in each tool β open-source options with no strings, web apps with usable free tiers, and the professional route when a plan needs to become a real drawing set.
Free with no strings (open source)
- Sweet Home 3D β the best-known open-source floor planner: drag-and-drop rooms and furniture with a live 3D preview. Ideal for home layouts; not a drafting tool.
- LibreCAD / QCAD Community β open-source 2D CAD for dimensioned, to-scale plans. More effort, professional output.
- FreeCAD β full parametric CAD/BIM; overkill for one room, right for a real project.
Web apps with real free tiers
Floorplanner, Planner 5D, RoomSketcher and similar all offer browser free tiers β quick and pretty, but exports, high-res renders and project counts sit behind the paywall, and their terms change often. Fine for a moodboard-grade plan; check current limits before committing a project.
What architects actually use
Real projects live in BIM β Revit, Archicad, Vectorworks β where the floor plan is a by-product of the building model. Students can get those free or nearly free through education licenses: see the free architecture software guide.
