I’m not really sorry to hear this. WPSiteSync is certainly an interesting idea but as you point out it’s got to be tough keeping track of frequent, major plugin changes. Syncing databases is extraordinarily difficult.

Perhaps the ServerPress team will put some effort into updating their much more interesting (and in my opinion much more useful) DesktopServer app. It hasn’t been updated at all since 2019, and there hasn’t been a significant update for much longer.

I’ve finally had to make the switch to Local by Flywheel. Local’s a fine, workaday local environment, but DesktopServer Pro was always quicker. I used it daily for more than 10 years as my main development and troubleshooting/rescue/repair platform.
