Floor Plan Maker
Genuinely free, genuinely no sign-up, and it produces three plan styles including a 3D isometric view that reads well in a listing or a client conversation. For sketching renovation ideas or comparing room arrangements that is a fair trade. What it will not do is let you nudge a wall — the generator returns finished concepts, and manual editing means exporting into the separate editor tool.
Pros
- No sign-up, no cost and no watermark on personal-use plans
- Three output styles: technical, 2.5D and 3D isometric, from the same input
- Space presets for house, office, restaurant, classroom, garage and kitchen plus custom
- Connected tools carry a plan onward into rendering, 3D, interior design and virtual staging
Cons
- The generator returns finished layouts — editing means moving to a separate editor tool
- Vendor explicitly says plans are not construction-ready without professional review
- No company address or country is published, only 'Floor Plan Maker INC'
- No paid tier means no stated support or reliability commitment
