A few months ago I went on a quest for a DNS server and was dissatisfied with current maintained projects. They were either good at adblocking (Blocky, grimd…) or good at specifying custom DNS (CoreDNS…).

So I forked grimd and embarked on rewriting a good chunk of it for it to address my needs - the result is leng.

• it is fast
• it is small
• it is easy
• you can specify blocklists and it will fetch them for you
• you can specify custom DNS records with proper zone file syntax (SRV records, etc)
• it supports DNS-over-HTTPS so you can stay private

I just released a new version which includes full NixOS support via a module! ❄
