I Built ScaleMap Over a Weekend After Talking to Interior Designers
Short summary
ScaleMap is a privacy-first spatial planning tool for homeowners, designers, and architects to visualize room layouts in 2D and 3D. Built in response to user interviews revealing frustration with overly complex or from-scratch design tools, it lets users upload blueprints, arrange furniture, and test layouts locally with no tracking. The indie-hacker approach validates demand before over-engineering.
