Wi-Fi and networking, made simple
Networking jobs tend to be small but frequent: you need to hand a visitor your Wi-Fi password without reading it out, scan a QR code that another tool generated, look up a domain's DNS records, work out how many hosts fit in a /26, or find out which vendor made a device you only know by its MAC address. These tools cover those everyday tasks with no app to install and no data leaving your browser.
The Wi-Fi QR generator and the subnet calculator run entirely on your device, and the MAC lookup matches against a bundled vendor list, so your inputs stay private. As a Progressive Web App, the whole toolset installs to your home screen and keeps working offline when you are out in the field.
