Best Free Home Design Software
The best truly free home design software is Sweet Home 3D — open-source, no watermark, no project limit, and clean 2D and 3D export. Planner 5D and SketchUp for Web are also free and easier to start with, but Planner 5D watermarks renders and locks half its catalog, while SketchUp Free only exports SKP, PNG, and STL.
How they compare
Ordered by overall fit — free-tier value, output quality, platforms, and ease.
Plan Your Room
Truly freeEntirely free to lay out rooms in 2D and basic 3D with exact dimensions, but there's no paid tier and no real file export; you print to keep a copy, and the save system is widely reported to lose work.

Sweet Home 3D
Truly freeCompletely free and open-source for personal and commercial use with no feature paywall; the only real limit is that the online and mobile versions can't import custom 3D models or export OBJ, which the desktop app handles.

Arcadium 3D
Free, with limitsFree forever (not a trial) with the full library and real-time 3D, but capped at 2 projects and roughly 30-50 objects each, with no custom-model import and only limited AI render credits before you need Pro.

Cedreo
Free, with limitsThe free plan gives 1 project and only 5 photorealistic renders that are watermarked and personal-use only, with no blueprint download and no commercial use; everything beyond that requires a paid plan.

Coohom
Free, with limitsFree to design and view in 3D in-browser, but free renders are capped at around 10 standard renders a month and carry a Coohom watermark; HD/4K, panoramas, videos, and watermark removal all require a paid plan.

Floorplanner
Free, with limitsFree to design in 2D/3D with the full library, but every free export is locked to SD (960x540) with a Floorplanner watermark, and HD/4K, watermark removal, multiple floors, and DXF/PDF export all cost credits.

HomeByMe
Free, with limitsFree design with unlimited 2D/3D screenshots, but you get only 5 realistic HD renders total for the account's lifetime (not per month), deleting a project doesn't refund the credit, and free is personal-use only.

Homestyler
Free, with limitsFree to design with unlimited 1K renders and 100k+ models, but every free render carries a Homestyler watermark, removing it needs a paid plan, and 4K renders cost $1.99 each a la carte.

Live Home 3D
Free, with limitsThe free version limits you to one active project at a time, watermarks all image and video exports, and disables 3D-model export entirely; a one-time Standard purchase removes those limits.

Planner 5D
Free, with limitsFree to design unlimited 2D/3D projects, but about half the furniture catalog is locked, you get no proper renders, and DWG/DXF export plus custom 3D import require the Professional plan.

RoomSketcher
Free, with limitsFree to draw accurate floor plans and view low-res 3D snapshots, but you can't download, print, or export a finished 2D/3D plan until you pay about $4 per output or subscribe to Pro, and free is capped at 2 projects.

Roomstyler
Free, with limitsFree to design in 3D with the full real-brand catalog, but you must sign up to render, free renders are low-res (around 640x480) and watermarked, and HD downloads require credits.
