The honest comparison
Where Cona is different
Sweet Home 3D is a genuinely free, open-source classic that runs offline, and that is a real strength. It is also mainly a desktop download with a dated interface and a generic, non-shoppable catalog. If you want a modern, browser-based planner with real furniture you can buy, Cona works differently.
Nothing to install
Cona runs in your browser on any device. Sweet Home 3D is mainly a desktop download. It also has an online version, but Cona is browser-first by design.
Real furniture you can buy
Cona's catalog is real pieces from brands like IKEA, CB2 and Herman Miller you can shop. Sweet Home 3D's 10,000+ models are generic and not for sale.
Modern and maintained
Cona is actively built with a current interface. Sweet Home 3D is a free, open-source classic, dependable but dated, with a smaller community.
