   DN$ – an innovative, ad-supported DNS resolver▲294

   Tired of companies snooping through your DNS traffic? Don't you wish you could get advertisements with your DNS records? Today we're introducing the innovative, privacy-focused, ad-supported DNS resolver - DN$! Traditional DNS resolvers provided by your internet service provider, cloudflare, or google could be tracking your internet activity and selling it to third-party data vendors. We at DN$ want to fix that and cut out these nefarious actors (until we've amassed a critical number of users to exploit). In order to support such a radically new business model, our service needs to serve…

    Sinkzone DNS – Forwarder that blocks everything except your allowlist▲96

    Most site blockers work by blacklisting distractions. That never worked for me, the internet is too big, and there’s always something new to waste time on. I wanted the opposite: allowlist‑only browsing. Block everything by default, and explicitly allow only what I need. So I built Sinkzone: a local DNS forwarder with two modes: Monitor mode: lets all traffic through, but logs every domain so you can decide what to allow. Focus mode: only allowlisted domains resolve; everything else is blocked (NXDOMAIN). It’s open source, written in Go, and runs locally on macOS, Linux, and Windows. Works a…

    Osint tool that finds exposed files on domains▲58

    hey guys, wanted to show one of my side projects i just made public. the idea is basically another osint tool for pentesters and bug bounty hunters. it watches certificate transparency logs and checks newly-seen domains for exposed stuff like .env files, open .git dirs, config files, db dumps and so on, and puts whatever it finds into a searchable db. you just search a domain (or part of one) and see what's exposed. it's read-only and free. one thing i've been thinking about adding is a way to register for certain keywords and get notified when something new shows up for that search. would…

    Netfence – Like Envoy for eBPF Filters▲58

    To power the firewalling for our agents so that they couldn't contact arbitrary services, I build netfence. It's like Envoy but for eBPF filters. It allows you to define different DNS-based rules that are resolved in a local daemon to IPs, then pushed to the eBPF filter to allow traffic. By doing it this way, we can still allow DNS-defined rules, but prevent contacting random IPs. There's also no network performance penalty, since it's just DNS lookups and eBPF filters referencing memory. It also means you don't have to tamper with the base image, which the agent could potentially manipulate…
