- SiteCheck SiteCheck is a MacOS desktop software inspired by https://ipcheck.ing. The official website is sitecheck.top. I have always been a loyal user of ipcheck.ing. Whenever I switch proxies, check lines or check DNS exports, my first reaction is to open it and take a look. It was precisely because I had used it long enough that I gradually came up with the idea of making a similar gadget myself. SiteCheck is built on this basis. It is a lighter local app that is dedicated to the macOS menubar. It isolates the things I use most frequently: checking connectivity, looking at DNS tests, and taking a look at the current public IP. I don’t want to replace ipcheck.ing, but I want to make the part of my experience that I click on repeatedly every day into a more direct gadget. In addition, we need to pay tribute to Achan for bringing us such a useful tool.
