I built a DNS resolver from scratch in Rust – no DNS libraries
I built a DNS resolver that lets me use https://frontend.numa instead of localhost:5173 — auto-generated TLS certs, WebSocket passthrough, path routing. No mkcert, no nginx, no /etc/hosts.
I built a DNS resolver from scratch in Rust – no DNS libraries launched on April 2, 2026 with 115 votes, #333 of 21,248 launches that month and more than 95% of that year's launches.
In plain words
This is a DNS resolver written in Rust that enables developers to access local services using custom domain names with HTTPS instead of localhost addresses. It automatically generates TLS certificates, supports WebSocket connections, and handles path-based routing without requiring additional tools like mkcert, nginx, or manual hosts file editing. The tool is designed for developers who want to simplify local development environments.

I built a guided Build your own DNS Server challenge2023 · app.codecrafters.io · ▲57Hey everyone. It's Sherub here, author of the Build your own DNS Server challenge on CodeCrafters. Currently it’s available in Rust, Go, and Python and is free while in beta. https://codecrafters.io/dns-server I've kept the challenge accessible but still challenging for an intermediate developer. This challenge, like others from CodeCrafters, is self-paced. You can use any tools you prefer (terminal, editor, etc.) to build the project. At the end of the challenge, you will have created a DNS forwarding server. The server can create and read DNS packets and respond to DNS…
DN$ – an innovative, ad-supported DNS resolver2024 · github.com · ▲294Tired 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…
IP Guide – Info on IP addresses, Networks, and ASNs2023 · ip.guide · ▲363Hey all, wanted to share my recent weekend hack project. I wanted to improve upon the existing space for looking up information about IP addresses and ASNs. The backend is written in Rust and pulls BGP data every 8 hours from the RIPE RIS project to build up a routing table and also adds geolocation information. The frontend is using React and Tailwind. Would love any feedback or suggestions on what to improve.

I'm rewriting a web server written in Rust for speed and ease of use2025 · ferron.sh · ▲68Hello! I got quite some feedback on a web server I'm building, so I'm rewriting the server to be faster and easier to use. I (and maybe some other contributors?) have optimized the web server performance, especially for static file serving and reverse proxying (the last use case I optimized for very recently). I also picked a different configuration format and specification, what I believe is easier to write. Automatic TLS is also enabled by default out of the box, you don't need to even enable it manually, like it was in the original server I was building. Yesterday, I released the first…

Talanoa▲340Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
