While this is true, the reader is really the only one that can choose for themselves and Cloudflare is a valid option, even if it isn’t the most purist method available.

Mealie +1

I’ve tried Mealie, Tandoor, Paprika and KitchenOwl. Mealie was by far the best looking, easiest to navigate and most convenient. They revamped the shopping list recently and it has replaced my old Google Keep method.

You’re only thinking of public use cases. For personal use, as I’m sure most people self-hosting would be using it for, it’s very convenient. I use it for work for typing long urls into a new computer we don’t yet have remote management of yet. At home, it makes it really easy to type any link with a TV remote or controller.

I’ve heard DuckDNS has become more unreliable. You could try another service like afraid.org and see if it makes a difference.
