Google contacts does a good job synchronizing my contacts across devices and email. I am trying to degoogle myself and looking for stable alternatives

I definitely prefer to host my contacts with my email, so they moved to Fastmail when my email did. What email service are you using? Most email services use CardDAV-compatible contact sync of some flavor, nothing Google is doing there is particularly innovative.
