What are the good alternatives? In domain business, everyone like a service which has lived for decades. GoDaddy being the one helps a lot.

I love Cloudflare for my .com domains but they don’t support a lot of TLDs till date.

Porkbun.com Been around since 2015. You decide if that's long enough.

For my extremely simple needs, the website is domain name magic for a plain customer wanting a plain service.

If you prefer to use a service that's been around for a really long time, Network Solutions will happily sell you a domain! (Maybe Tucows, too; their domain-registering arm is now called OpenSRS, it appears.)
