They use Gandi under the hood. Using Gandi directly is a much better experience

If your servers are in AWS, then Route53 is a no-brainer - it lets you do things no other DNS host can do, and it's infinitely better plumbed into the AWS ecosystem (CloudFormation automation, etc.)

Can also recommend them. No race-to-the-bottom scammy upsell shit since... it's basically just there as a value-add on AWS. And you're piggy-backing on all the infrastructure/support/etc that people expect from AWS instead of a domain registrar where people are generally shopping pretty exclusively on price.

And you can expect that they're not going to turn _into_ a scammy registar at any point since, well, it's AWS.

I second Route 53 for domains. It’s straight to the point and clear cut unlike other registrars that try to upsell gimmicky features at every step.
