🚀 Cozystack Recognized in CNCF's CNAI Landscape!

We're thrilled to share that Cozystack has been added to the Cloud Native AI (CNAI) Landscape by the Cloud Native Computing Foundation (CNCF)! This is a significant validation of our work in bridging cloud-native infrastructure with AI workloads.

Why This Matters:
• Industry Recognition: Being featured alongside major players confirms Cozystack's role in shaping the future of AI infrastructure
• Technical Validation: Highlights our capabilities in GPU provisioning, scalable Kubernetes deployments, and platform engineering for AI/ML
• Ecosystem Growth: Strengthens our position in the open source cloud-native community

A huge thank you to our contributors, users, and the CNCF community for making this possible! This is just the beginning of our journey to simplify AI infrastructure deployment.

🦾 How Cozystack Was Born: The Philosophy Behind Its Architecture

Word to Andrey Kvapil, Creator of Cozystack and Founder of Ænix:

Well, I’ve long been passionate about the idea of building a cloud platform with a Kubernetes-native API interface.

I think the core ideas started to take shape when I was working on the kubefarm project. But later, I realized that the folks at Talos had implemented many of the things I was aiming for even better than I did five years earlier. So we decided to join the Talos community instead of developing our own solution from scratch.

Many of the technologies we use today were already in play back then: Kubernetes-in-Kubernetes, LINSTOR, Cilium, PXE boot, and more.

Some of my insights also came from developing the Deckhouse platform, where I introduced a virtualization layer using KubeVirt. That experience made it clear how important reproducibility and repeatability are. It also showed how difficult it can be to support multiple distributions and out-of-tree forks.

That’s why we have this motto:

If we build a platform feature that could be useful in an upstream project, we prefer to contribute it there rather than keep it in the platform.

This principle actually inspired by the KubeVirt razor 😅

So, piece by piece, Cozystack was shaped from different technologies and ideas over time. All that was left was to unify them into a single product.

Cozystack started as an attempt to package and deliver our accumulated experience as a ready-to-use solution for a wider audience. It brings together all the cozy technologies we’ve relied on for years under one product.

We’re deeply grateful to all the opensource project we use, and we truly collaborate with their maintainers. We’ve also built our own cozy community across it, and we’re immensely thankful for it.

It’s important to understand that Cozystack began as a self-bootstrapped project, without any external investment. So going to production and generating real value was our primary goal at the beginning.

In this article Andrei Kvapil explores how virtualization has evolved from DIY hypervisors to turnkey managed platforms and why this shift is critical for modern infrastructure.

Key takeaways:
🔹 The rise of "as-a-service" models – Why enterprises are ditching complex self-managed setups
🔹 Local providers’ advantage – How regional players outperform hyperscalers in digital sovereignty and compliance
🔹 The new stack – Kubernetes, lightweight VMs, and automation redefining virtualization

Big news! Cozystack just became an officially Certified Kubernetes Platform and passed all the tests✅

Thanks to our community and our good friends from Hidora.

In our new article we’ll walk through the way we deliver applications to Kubernetes, explain why regular GitOps can be awkward in local development, an show how the new tool cozypkg fixes those pain points.

The article targets engineers who already know Helm and Flux.

It’s been a while since we last covered Cozystack’s updates — time to fix that! We’re thrilled to showcase a wealth of new features and key improvements in this roundup. For brevity, we’ve curated only the most significant changes here (you’ll find all fixes and enhancements in the release notes, linked throughout the article).

Let's see what we've done😅

https://blog.aenix.io/cozystack-v0-31-0-33-ae241c739b23

The latest CNCF Projects Velocity Report is out, and we’ve got great news—Cozystack nearly cracked the top 100 most active projects! We landed at #101 🙄

Here’s a quick activity snapshot:
👉 Commits: 2,553
👉 PRs: 978
👉 Issues: 312
👉 Contributors: 48

Huge thanks to our community for your incredible contributions! You’re the best! 😘

Next year, we’re coming for Kubernetes in this ranking. And in a couple more years? We’ll declare Cozystack a programming language and storm the TIOBE index! 🤥

What is the horizontal axis ?
