Best free floor plan software (2026)

What "free" really gets you in each tool — 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 — 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 — open-source 2D CAD for dimensioned, to-scale plans. More effort, professional output.
FreeCAD — 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 — 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 — Revit, Archicad, Vectorworks — 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.

Software for blueprints — the same question, older word

If you searched "software for blueprints", the honest translation: nobody produces blueprints anymore (the word survives, the ammonia-print process didn't) — you want either a dimensioned 2D plan (the LibreCAD/QCAD route above, or a free AutoCAD alternative if DWG compatibility matters) or a construction drawing set, which is BIM territory. For reading someone else's "blueprints", the free viewers in the software guide open DWG, PDF and IFC without a license.

Common questions

What is the best free floor plan software?

Sweet Home 3D as the fully free desktop option, the browser planners with usable free tiers for quick layouts, and real CAD (LibreCAD, QCAD, FreeCAD) once a plan must become a drawing set.

Can I draw a floor plan without downloading anything?

Yes — the browser-based planners run on free tiers and are the fastest route for a simple layout. Export limits and watermarks are where the free tiers usually end.
