Arcadium 3D Alternatives (Real Limits Compared)
Arcadium 3D is a solid choice, but people look for alternatives because of the fine print: Free 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. On top of that, free is capped at 2 projects and roughly 30-50 objects, tight for whole homes. Strong options to compare include Planner 5D, Homestyler, Floorplanner, and Coohom. Below we line up the real free limits of each — what it exports, what it watermarks, and which platforms it runs on — so you switch for the right reason.
Alternatives at a glance
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.
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.
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.
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.
