Why people look for a browser WiFi heatmap
Many WiFi tools are install-heavy, predictive-first, or built for enterprise survey workflows. WiFi Heatmapper is designed for the simpler job: visualizing measured WiFi coverage on a floor plan directly in the browser.
- Create a floor plan WiFi heatmap from real readings.
- Visualize WiFi coverage in a home, apartment, office, or small building.
- Find dead zones and weak signal areas without installing bulky software.
- Keep the workflow local-first and privacy-friendly.
Unlike predictive WiFi planners, WiFi Heatmapper focuses on showing the coverage you actually measured.
