Unbound

Unbound is a validating, recursive, and caching DNS resolver.

The C implementation of Unbound is developed and maintained by NLnet Labs. It is based on ideas and algorithms taken from a java prototype developed by Verisign labs, Nominet, Kirei and ep.net.

I used it to hide my DNS from statist spies. With DNScrypt as SimpleDNScrypt. It did work, but often broke down. I had to waste extra time to fix it by restarting the unbound service. Today I got fed up with it and switched to the Acrylic DNS proxy. So far it's been working fine. Unbound will no longer break on me.

AI Slopfree Software Catalog

A more optimistic homage to the slopware catalog https://alternativeto.net/lists/44427/slopware/, this list is designed to showcase projects, both FOSS and proprietary, which reject contributions from Generative AI LLM slop machines. The most pessimistic thing about this list is how short it is and how so many commonly used software solutions and websites are not included. I have to give it up to the following sites for providing references: https://codeberg.org/brib/slopfree-software-index https://github.com/melissawm/open-source-ai-contribution-policies There are a lot more projects on this list which I didn't include because they aren't on AlternativeTo (yet). I'll be adding more entries to this site (and removing those who fold to the AI overlords) on a regular basis. I'm including references, which are all first-hand declarations from the development teams for each entry to ensure items aren't included based on hearsay or conjecture. Updated 10-2-2026

This list is inspired by the Kamran Ahmed's "2020 Developer Roadmap," now at roadmap.sh Without further ado, my take on the most important technologies to learn for dev-ops in 2020!

Be careful what you paste into a terminal. Check what a command installs before running it.

What is Unbound?

Unbound is a validating, recursive, and caching DNS resolver.

The C implementation of Unbound is developed and maintained by NLnet Labs. It is based on ideas and algorithms taken from a java prototype developed by Verisign labs, Nominet, Kirei and ep.net.

Unbound is designed as a set of modular components, so that also DNSSEC (secure DNS) validation and stub-resolvers (that do not run as a server, but are linked into an application) are easily possible.
