📌📌📌 Cozystack v0.37: Brand New UI
In the new release, the Cozystack developer community unveiled a completely new UI based on the openapi-ui project. The maintainers fully rewrote the platform’s frontend, delivered numerous improvements, and fixed issues that existed in the previous Kubeapps-based UI. Let’s see what’s inside.
Cluster selector
A cluster selector has been added. Today, the dashboard operates in single-cluster mode (one dashboard per cluster). The same UI will power multi-cluster mode in future releases.
Namespace navigation (Tenant Namespace)
On the cluster view, you now see all namespaces you’re ennoscriptd to. The list is built via the Kubernetes API aggregation layer (tenant namespace), so only namespaces you have access to are shown.
Application categories
Existing applications are split into three categories. In upcoming releases, categories will be optional — you’ll be able to deploy only selected groups and skip others.
Richer resource pages
Every resource page now includes:
- a resource table and basic metadata,
- Conditions,
- Workloads (what’s currently running),
- Ingresses, Services, Secrets,
- the resource YAML.
OpenAPI-driven configurators
Resource creation uses forms auto-generated from the Kubernetes OpenAPI spec. Field definitions and validation come directly from the spec — no YAML comments needed.
Spec generation from Helm
New application specs are generated from Helm charts using the cozy-values generator. Fields you add in the form are reflected live in the resulting YAML.
Tenant administration separated
Tenant management modules have moved to a dedicated Administration section: create sub-tenants and deploy tenant-specific modules/apps there (subject to your role and permissions).
VM features groundwork
A VNC console tab for virtual machines is planned and will appear as an additional tab. Certain resource types (e.g., KubeVirt VMs) will gain specialized tabs/fields.
New Components Versions
Flux Operator 0.29.0
Cilium v1.17.8
Velero v1.17.0
openapi-ui v1.0.3
LINSTOR v1.32.3
SeaweedFS v3.99
All changes: v0.37.0, v0.37.1, v0.37.2, v0.37.3, v0.37.4

🦾🦾 Cozystack and Ænix at KubeCon’25, Atlanta: Lightning Talk + CNCF Project Pavilion
Who will be on behalf of our team: Andrei Kvapil, our CEO and Cozystack maintainer.
1. Lightning Talk: November 10, 2:46pm - 2:51pm
Building C | Level 3 | Georgia Ballroom 2
Cozystack: Build Your Own Open Source AWS On Bare Metal - Andrei Kvapil, Maintainer
Kubernetes and cloud infrastructure are the de facto standard. Many teams default to public clouds (AWS/GCP/Azure)—convenient, but not for everyone. Vendor lock-in, data control, and compliance push workloads to bare metal. i'll explain in a five minutes how Cozystack enables businesses to build open-source bare-metal infrastructure with cloud-like ease and zero vendor lock-in, while empowering service and hosting providers to compete with hyperscalers.
2. CNCF Project Pavilion: November, 11, 10:30 AM - 3:00 PM
Kiosk: 14B
Let's meet in Atlanta, November 10-13 and talk about your clouds and cloud platforms!
P.S. To assign a meeting with Andrei write to @tym83.

💪 We’re excited to introduce the talk "How we build a multi-AZ cloud in Switzerland", by Matthieu Robin (Hidora) at CozySummit Virtual 2025.
CozySummit will take place online on December 3, 2025. The session starts at 16:05 CET (9:05 AM CT).
What this talk is about: "As a cloud provider, we spend time to find a solution to make a multi-AZ IaaS solution. Our goals was to find the best orchestrator, the very high-availability system, and give the full secure system to our customers. I'll talk about our journey with different solutions and then Cozystack. Speaker: Matthieu Robin CEO by Day, DevOps Evangelist Always Company: Hidora Passionate entrepreneur & CEO of Hidora, leading cloud/DevOps adoption. Founder of DevOps Geneva Meetup & DevOpsDays Geneva. Professor at HEG teaching Service Industrialization. Volunteer firefighter committed to community service. Dedicated to innovation, education & fostering DevOps collaboration".
Register for CozySummit here: https://community.cncf.io/events/details/cncf-virtual-project-events-hosted-by-cncf-presents-cozysummit-virtual-2025
This event will showcase how Cozystack empowers teams to build their own full-featured private clouds or AWS-alternative public clouds on owned or leased hardware. Learn how Cozystack reduces public cloud dependency, ensures data control, and enables digital sovereignty.

💪 We’re excited to introduce the talk "Home Lab to the Moon and Back", by Kingdon Barrett (Navteca, LLC) at CozySummit Virtual 2025.
CozySummit will take place online on December 3, 2025. The session starts at 16:40 CET (9:40 AM CT).
What this talk is about: "Running CozyStack in a home lab can be equal parts fun and furnace — especially when unused workloads turn into a very real space heater. This talk explores the practical tradeoffs involved in running CozyStack at home, some strategies for shifting services to the cloud or serverless, and powering down X86 nodes for ARM64 to save energy and cut down on waste heat - while still maintaining a high standard of availability and measuring the performance on the CozyStack platform. We'll look at ways to measure the actual energy cost of a CozyStack cluster, strategies for moving or pinning workloads by architecture with node selectors, and trade-offs of relying on external storage to keep the footprint lean. Along the way, I'll give a demo of SpinKube, built on top of custom Talos images (with a spin runtimeclass extension), showing how the developer experience for CozyStack enables deep customization and hands-on experimentation with Talos Linux. The focus isn't on one right setup, but on how CozyStack makes it possible to explore, measure, and balance cost, energy, and reliability in any environment - whether in the basement, the cloud, or somewhere in between. Speaker: Kingdon Barrett Flux Maintainer, DevOps Engineer Company: Navteca, LLC. Kingdon Barrett is a Flux maintainer and a DevOps Engineer at Navteca, presently working on a project called Science Cloud for the Goddard Space Flight Center and Science Mission Directorate at NASA. He is a Ruby/Go developer. Find Kingdon at Flux Bug Scrub!"
