About OpenPlan3D

Floor planning tools should be free, fast, and work everywhere.

The Vision

OpenPlan3D started from a simple idea: everyone should have access to a powerful, easy-to-use floor plan editor — without paying for expensive software or creating yet another account.

Whether you're rearranging your living room, planning a renovation, or designing a new home from scratch, OpenPlan3D gives you professional-grade tools right in your browser. Draw in 2D, visualize in 3D, furnish with real models, and export in any format you need.

Completely Free, No Catches

OpenPlan3D is 100% free. There's no premium tier, no paywalls, no feature gating, and no signup required. Every feature is available to everyone, always.

We believe design tools should be accessible to everyone — whether you're a homeowner sketching ideas, a student learning interior design, or a professional creating client presentations.

Open Source

The floor plan editor is fully open source and available on GitHub. We welcome contributions, feedback, and feature requests from the community. Inspect the code, fork it, build on it.
