Hey Product Hunt! I'm Mohammed, a developer from Iraq. I built Simple Plan Space because I was designing a house and couldn't find a simple free tool that just let me draw rooms on a grid without installing AutoCAD or paying for a subscription. This started as a personal project — I was designing a traditional Damascus-style courtyard house and needed a way to visualize and rearrange rooms. The tool grew from a static SVG floor plan into a full interactive editor with doors, windows, columns, undo/redo, and mobile support. It's completely free, open source, and works without an account. I'm a solo developer so I'd love your feedback on what to add next. Some ideas I'm considering: room templates, multi-user collaboration, and DXF/DWG export for architects. Try it out, break it, and let me know what you think!
