Is Tampermonkey BETA safe?
Tampermonkey BETA sends a persistent identifier and userscript names to its analytics server by default, without a consent prompt.
On fresh install, the extension has analytics enabled as its hardcoded default and begins transmitting data before any consent prompt appears. Each time a userscript is installed, updated, or removed, the extension sends the script name, its download URL, and a persistent 16-character visitor UUID to a.tampermonkey.net via Matomo. Separately, the extension contacts blacklist.tampermonkey.net every 24 hours and can display server-controlled notification text in its UI based on the response.

Shared hosts - 3 hostnames
Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.

Where it sends data
Destinations our analysis observed TM BETA contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
