Upload a floorplan, draw walls, drop access points, see the predicted signal coverage. No download. No account. No vendor lock-in.
No download · Works in your browser · Predictions use the COST-231 multi-wall model
PNG or JPG image of your space. Calibrate the scale by entering pixels per meter.
Drag-draw walls (drywall, brick, glass, concrete) and drop access points. Set Tx power and band.
Live heatmap shows predicted dBm. Move APs around to find optimal placement before drilling holes.
For a home lab or small office, none of these make sense. WiFi Heatmap is what you actually need.
We use the COST-231 multi-wall model, the same fundamental approach as commercial tools at the entry tier. Expect ±6–10 dB accuracy for typical homes and small offices. Big metal/concrete structures and 3D ceiling effects aren't modeled. Treat predictions as guidance and validate with a quick walking survey using a phone WiFi analyzer after install.
Yes. Floorplans, walls, and AP placements are stored entirely in your browser (localStorage). Nothing is uploaded to our server. We log only anonymous usage counters (operations performed) for product analytics.
Yes — that's the primary use case. Plan UniFi, Aruba Instant On, TP-Link Omada, or any vendor's APs before installation. Works on 2.4 GHz and 5 GHz. WiFi 6E/7 (6 GHz) coming soon.
The core tool is free with no signup required. Free tier supports up to 5 access points per floorplan and exports a watermarked PNG. Pro tiers (coming soon) will add unlimited APs, PDF reports, and project history.
For enterprise WLAN with hundreds of APs across multi-floor buildings, those tools are still the right answer. WiFi Heatmap is for home labs, prosumers, and small offices where €4,000+ price tags and complex 3D survey workflows are overkill.
