The community member is running 4 operating systems natively and asks if the AppImage on the website is the current build of Webstudio, offering to do some testing. The comments indicate that the app works on macOS, loads from the Webstudio cloud so it's always up-to-date, and has been reinstalled and is still working on macOS Ventura 13.3. Another community member notes that the app is running fine on Artix Linux (based on Arch) and will test it on other systems.
