About
WiFi Heatmap is a browser-based predictive WiFi planning tool that lets users upload a floorplan, draw walls by material type, and place access points from multiple vendors to visualize signal coverage as a heatmap. It uses the COST-231 multi-wall path-loss model to predict signal strength without requiring a physical walk-around survey. The free tier supports up to 5 access points, while a Pro tier removes caps and watermarks for a one-time or monthly fee.
Problem
Professional WiFi planning tools like Ekahau cost thousands of dollars per year, leaving home lab and small office users without an affordable predictive coverage planning option.
For
Home lab enthusiasts, prosumers, and small office IT planners
How it works
Users upload a floorplan image, draw walls by material type, drop access points from a vendor-neutral preset library, and the tool instantly renders a predicted dBm signal heatmap using the COST-231 multi-wall model — all in the browser with no server uploads.
