Porkbun. Yes, Cloudflare Domains exists but let's support the small guys.

I like https://www.dynadot.com/. Good prices and privately owned for 30+ years.

I've been a happy customer of https://njal.la/ for years

I moved all my from name cheap to porkbun years ago.

Two more are NearlyFreeSpeech and UnstoppableDomains.

The latter also supports crypto domains which have no chance of a takeover except by government order, although crypto domains require the client to install a browser extension or other software to resolve. The good thing about crypto domains is that there should be no renewal fee, although there will be a fee to update the record.

Porkbun!
