DNSimple

A DNS provider. I used DNSimple solely for dynamic DNS updates via pfSense when I lived in the US1). On February 2nd, 2025, I cancelled my account.

This is the only service I've used where I've felt like they sabotage you from every angle, despite offering a very good product. If you have a SaaS product and the subscription part doesn't work, and/or it angers your customers, why would they advocate for you? Usually services that offer generous free tiers are hoping you'll pick them at your job and eventually lead to an enterprise contract, but my experience was so bad that I'm genuinely shocked at how bad it was.

I really wanted to use it for all of my domains, but my experience left me pretty unhappy, so I never ended up moving any other zones.
