Cloudflare is pretty affordable and it seems unlikely to be bought by PE

I'm on EuroDNS as domain registrar for many years, parked there a couple of companies where I worked. They don't have scammy vibe of other registrars, have multi-user accounts, which is convenient for businesses.

Hetzner, OVHcloud are decent European options. I migrated to them after geopolitical risks with US providers got too high. No problems so far.

Dynadot. Over a decade without issues.

Porkbun has been good to me.

infomaniak.ch is swiss, and (relatively) good. Lacking features overall (though their domain+DNS is solid), but at least no bullshit like this
