Open tool →Why free tools?
Affiliate guides fund the site, but utility tools exist purely to help. They also happen to be useful starting points for the topics our guides cover — if the WiFi planner shows you need a mesh node in the kitchen, the WiFi mesh systems comparison guide is a logical next step.
All tools are open to inspect in the page source. No minified bundles, no external calls, no analytics on the tool inputs themselves.
