WiFi Heatmap
See WiFi dead zones before you drill the holes.

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.
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.
