A growing set of tools for scanning WiFi, mapping access points, and tinkering with IoT devices — built for curiosity.
Tools
Discover and map open WiFi access points reported by Android devices. Visualise sightings on a live map, track public IPs, gateway MACs and signal data.
Deploy an ESP8266 on any LAN and run automated diagnostics — ping, DNS, HTTP, subnet scan, WiFi survey — all from a web dashboard. No port forwarding needed.
Upload wardriving data or sync from the Android scanner to generate signal-strength heatmaps layered over OpenStreetMap tiles.
Connect sensors and build lightweight dashboards for temperature, humidity, power usage — or anything your device can measure.
Works on any screen — phone, tablet, or desktop.
Access points visualised on interactive OpenStreetMap tiles.
All data over TLS. OAuth login. No passwords stored.
A personal lab — new tools added as ideas get tested.
About
wiafi started as a weekend project to make sense of the WiFi networks visible from a window — how many are there, where are they, how do they move?
It grew into a small platform of connected tools: an Android scanner that walks the streets, an ESP8266 that probes the LAN from the inside, and a server that stitches it all together into maps and dashboards.
Everything here is built for curiosity and learning. All collected data is used only to improve the tools and visualisations on this site.
