I got a Raspberry Pi from my cousin and today I was going to setup Pi-Hole to block ads on my home network. But this looks like a great alternative. I can probably use the Raspberry Pi for something else now. I will try to setup NextDNS and yeah as you said 20$ a year isn't a big deal for such a good protection. I wish they accept the payment through crypto. 😉😀 I would probably go with a free plan for now and see if that is sufficient for me and then choose a bigger plan if it isn't sufficient.
Edit: Just found out that they accept cryptocurrencies too.
All prices are in INR. We accept cards, PayPal and cryptocurrencies.
