Run your RethinkDNS on Cloudflare Workers 

What is RethinkDNS?

RethinkDNS is a fast, secure, private, transparent, configurable DNS resolver and a firewall. RethinkDNS works like NextDNS but NextDNS has a limit of only 300,000 requests/month.

And I hear someone said that RethinkDNS will not be free anymore 🤔

RethinkDNS

RethinkDNS is open source and we can install it on Cloudflare Workers with 100k requests/day (so good!). So we will be able to use it freely without being limited like NextDNS.

Setup Github and Cloudflare

Fork this project: https://github.com/serverless-dns/serverless-dns

Then click  Action > I understand my workflows, go ahead and enable them.

Go to tab Workers on Cloudflare dashboard and set up a custom subdomain for your workers.
