24 alternatives to Backname.io – every IP address gets its own domain
I was setting up tests involving DNS resolution recently, where something like 127.0.0.1.service.foo would have been tremendously useful. Back in the day, I'd have used xip.io - but sadly that service died. Well, every excuse is a good one when it comes to writing a DNS server! Backname.io joins nip.io and sslip.io in the wildcard DNS game.
Backname.io is a wildcard DNS service that automatically resolves IP addresses embedded in domain names to those addresses. Developers and testers use it to set up DNS resolution testing without manual… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Backname.io – every IP address gets its own domain launched in 2023; newer entries below may have overtaken it.

We launched an API for custom hostnames today. A simple HTTP post with a hostname gets a temp hostname with CNAME/a record instructions, as soon as DNS is setup we issue SSL and start accepting traffic for that hostname. It's the quickest way we know of to provision custom hostnames: https://fly.io/mix/custom-hostnames/ When we started building Fly, we figured it was too late to "make SSL easy and the customers will come". Lets Encrypt changed the world, and we knew many companies rolling their own SSL support with nginx, Traefik, etc, etc. It seemed like a…

Hey 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 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.

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…

Every privacy-focused DNS service requires an account: NextDNS, Cloudflare for Families, Apple's iCloud Private Relay (paid, iOS-only). The protocol that doesn’t require one - ODoH - had basically one well-known public relay operator (Frank Denis on Fastly Compute, default in dnscrypt-proxy). I built a second one and the client to talk to it.

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…
