Truly free

Genuinely free, open-source home planner with built-in photoreal rendering and no paywall.

The short answer

The rare no-strings option: open-source (GPL), free for personal and commercial use, works offline, and even includes built-in photorealistic rendering at no cost. The trade-offs are a dated Java interface, slow CPU-only renders, and a smaller default catalog. It's also the only tool here that runs on Linux.

Sweet Home 3D in depth

Why Sweet Home 3D is the pick for a truly free planner

Sweet Home 3D is the rare no-strings option: it is open-source (GPL), free for both personal and commercial use, runs fully offline, and — unusually — includes built-in photorealistic rendering at no cost and with no watermark. It draws accurate to-scale floor plans, exports PDF, PNG, SVG and OBJ without paywalls, and is the only tool in its class that also runs on Linux alongside Windows, macOS and mobile.

For a budget-conscious DIYer, a renter planning a layout, or anyone who refuses to hand their project to a cloud account, it is the safest recommendation on the whole directory.

The trade-offs of open-source

The cost of all that freedom is polish. The interface is dated Java and feels clunky next to modern cloud rivals, the photorealistic renders are slow because they are CPU-only, and the default furniture catalog is smaller than commercial competitors (though free extra libraries exist). The online and mobile versions also cannot import custom 3D models or export OBJ — only the desktop app handles those.

If you want a modern UI, fast GPU rendering, or a giant brand catalog out of the box, a commercial tool will feel nicer; if you want zero limits and zero cost, the rough edges are worth it.
