Parental Control - Add Custom Website?

I agree. This is badly needed.

By and large, I've preferred NextDNS to my custom Pi-hole setup ever since making the switch, but, alas, this may well turn into a deal-breaker for me, especially as I consider upgrading to a paid tier. Also, I hasten to point out that this feature has been requested elsewhere on this forum at least twice:

• https://help.nextdns.io/t/g9h40j5/
• https://help.nextdns.io/t/y4h0a36/

NextDNS, are y'all planning to implement this? Any update, even if it's a resounding no, would be appreciated. Thanks in advance.

For a solid, long lasting approach, as you'll eventually need to block another website, and then another, and then another (there's always workarounds, mirror sites, etc), I recommend blocking the whole of the web and then allow listing some sites.

On Android my solution to use a custom list is to host it on Pastebin then install the Personal DNS Filter application by choosing NextDNS server and deactivating all the others.
