Starlight
Documentation sites on Astro, with self-hosted full-text search built in rather than bolted on. Mix React, Vue, or Svelte components in one site. Still pre-1.0 after three years.
OpenTechHub
The intelligence portal for the sovereign business. Discover vetted open source alternatives, strategic reviews, and playbooks to escape vendor lock-in and build a technology stack you truly own.

VitePress
Vue and Vite powered documentation sites. Markdown in, static HTML out, with a build fast enough that large sites stay pleasant. The stable line has been quiet for about a year.
Sphinx
The documentation generator behind Python itself. One plain-text source builds a website, a PDF, and an API reference pulled from your code. reStructuredText is the learning tax.
Docusaurus
Documentation as code. Your content stays as Markdown in your own Git repo and ships as static HTML you host anywhere. Search is the one piece you still solve yourself.
NSD
An authoritative-only DNS server from the Dutch non-profit NLnet Labs, run by DNS root servers and many TLDs. Minimal attack surface by design, BSD-3. It serves zones only, not recursion.
Unbound
A validating recursive DNS resolver from the Dutch non-profit NLnet Labs. Resolve from the root servers yourself, so no public resolver sees your lookups. A focused resolver, not a full server.
BIND 9
The reference DNS implementation much of the internet runs on, governed by the non-profit ISC, not a company. Authoritative and recursive, MPL-2.0. Configuration is manual and zonefile-driven.
PowerDNS
Carrier-grade open source DNS used by ISPs and telcos: authoritative server, recursor and load balancer in one GPLv2 codebase. EU-owned via Open-Xchange. The management UI and support are a paid tier.
AdGuard Home
A self-hosted DNS ad-blocker with encrypted DNS and DHCP built in, blocking ads across every device. Auditable GPL code that phones nothing home. A modern sinkhole, not a full authoritative server.
Resources
Essential frameworks for the modern decision-maker. Deep dives on licensing, deployment standards, and security to secure your digital stack.

Open Source did not fail in AI.
Open, capable, sovereign: in AI you get to pick two. The frontier models are proprietary and revocable, the open ones you cannot run or cannot match, and even Europe's champion runs on chips it will never make. Sovereignty is not the model you pick. It's the weakest layer beneath it.

Digital Sovereignty isn't for Sale.
"Buy European" has become Europe's answer to digital dependence. But a European vendor is one acquisition away from being American, and hosting on home soil won't stop US law. Real sovereignty isn't where your software comes from. It's whether you can leave it.

You do not need an Open Source Program Office.
Every digital sovereignty talk ends the same way: set up an OSPO, and the idea gets filed under someday. But the office is not the point. It is a container for the jobs your vendor used to do, priced into the license fee and now yours to own. Name who owns them and you are ahead of most.
