Knock on wood, I have not used them in quite a while.
I’ve been using Namecheap for years and have been happy with it. Why do you prefer Cloudflare? Is it for easier integration with Cloudflare services? How’s the pricing compared to Namecheap?
Sorry for the interrogation lol
One benefit of using Cloudflare DNS is that you can place a CDN on the domain apex. So if you’d like to have https://domain.com instead of https://www.domain.com then they can make that happen.
Cloudflare sells domains at cost. So yes, cheaper than any other registrar (including NameCheap and Porkbun), except maybe those who sell domains at a loss as a promo to rope you in and then kill you on the renewals.
Integration into their stack is a nice side effect, but really inconsequential. You can have your domains registered with any registrar and have your DNS hosted by any DNS hosting provider. Heck, you can run your own DNS servers if you want to.
