Central Command for Mac and Windows
The terminal in its own window. It loads the live site, so every update reaches the app on its own.
Mac
Open the downloaded file and drag Central Command into Applications. The first time, right-click the app and choose Open, then Open again. macOS asks once because the app isn't from the App Store. It needs macOS 12 or newer.
Windows
Unzip the download and open the Central Command folder. Run Central Command.exe. If Windows shows "Windows protected your PC", choose More info, then Run anyway.
Sign in the same way as on the website. Connecting BloFin happens inside the app, and other links open in your browser.
