Been using porkbun as the registrar and cloudflare for Dns, no complaints. I like the cloudflare interface better and like having Dns and registrar separate.
Keep in mind you can always use a different DNS provider who does support dynamic dns. For example you could use cloudflare (free) with a domain bought from Pork Bun.
I just transferred all my domains out of Namecheap into Porkbun. I think Porkbun is 10 to 50 cents more expensive than Cloudflare, but they seemed a bit easier to use and could hold all my TLDs. So far, a way better experience than Namecheap!
Never heard of them, but just looking at a registrar comparison chart, their renewal costs are pretty high. eg. $20 for .wiki renewal at Porkbun and $30 at Hover. Maybe they bundle in a lot of services along with it that make the price worth it? but unless you're taking full advantage of those (if they're offered) then you could def get a better deal elsewhere.
I switched over to Netim after Gandi announced their new prices and removed the free mailboxes. They're a bit pricey (close to current Gandi pricing) but it comes with a mailbox (1GB) and a 250MB website.
They were close to Gandi pricing. Gandi just hiked up their prices on most TLDs by 75-100%. For my next renewal all my domains show up as €28 now. Netim is actualy looking pretty good right now with €15-22. 😆
