For Heads of Platform Engineering — an IDP without the lock-in

Golden-path developer self-service without the lock-in

You build the platform every other team builds on. The win is golden paths and real self-service — multi-tenant Kubernetes, databases and environments developers spin up themselves — with no ticket queue and no closed vendor. Ænix delivers that as a turnkey internal developer platform, or builds yours on open foundations.

Pairs with: Developer self-service(/products/private-cloud-platform/) for a ready internal developer platform, or Internal Developer Platform build to design one to your org. Open-source core: Cozystack, Apache 2.0.

Where you are right now

  • Dev teams wait on tickets for environments, databases and clusters.
  • You’re weighing build vs buy for an IDP and wary of Backstage-only glue work.
  • Each team wants isolation; you need multi-tenancy without a cluster per team.
  • Leadership wants developer velocity numbers, not another platform that needs a platform.

What you’re actually trying to do

Turn infrastructure into a product: self-service provisioning of VMs, managed Kubernetes, managed databases and object storage, with tenancy, quotas and guardrails — so developers ship without filing tickets, and you don’t hand-roll the control plane from scratch.


Two ways Ænix helps you

1. Run a turnkey IDP. Developer self-service(/products/private-cloud-platform/) ships the multi-tenant control plane, self-service portal, service catalog and golden-path provisioning on the open-source Cozystack core. Your platform team curates; developers self-serve.

2. Build your own, with our team. Cozystack is the framework; Ænix is your outsourced platform-engineering team. We design tenancy, golden paths and the catalog around your org, integrate your CI/CD and identity, and hand over a platform your team owns. See platform engineering and IDP build.


Quick facts

  • What it is: a multi-tenant internal developer platform (self-service VMs, K8s, DBs, storage) on a Kubernetes-native core.
  • Who it’s for: Heads / Directors of Platform Engineering, Platform / DevEx leads.
  • License: Apache 2.0 — no per-seat platform tax.
  • Status: built on Cozystack, a CNCF project (Sandbox 2025-02-28; Incubating expected late summer 2026).
  • Common pitfall: buying a portal (Backstage) with no real multi-tenant backend, so self-service still bottlenecks on infra tickets.

Why platform teams pick Ænix

  • A real backend, not just a portal. Multi-tenant compute, storage and databases under the self-service layer — the part Backstage doesn’t give you.
  • Authors as partners. Ænix maintains Cozystack; you get the people who built the tenancy model.
  • Own it. Open source and your infrastructure — no renewal that holds your developer experience hostage.

FAQ

How is this different from Backstage? Backstage is a developer portal; it needs a platform behind it. Cozystack is that platform — multi-tenant compute, K8s, databases and storage. You can put Backstage on top; the backend is the hard part we solve.

Can teams get real isolation? Yes — nested tenants with quotas and RBAC, so each team self-serves inside guardrails without a cluster sprawl.

Build or buy — which should we do? The discovery call scopes it. Teams wanting speed take the Developer Self-Service; teams wanting a bespoke fit take the build-with engagement where we’re your platform bench.

Does it run our existing workloads? VMs (KubeVirt) and containers on one platform, plus managed databases and S3-compatible storage — so legacy and cloud-native coexist.

What about cost? Apache 2.0 core, no per-developer licensing. You pay for support and/or the build. We model it on the call.

Ænix is the team behind Cozystack — a CNCF project (Sandbox today; Incubating expected late summer 2026), Apache 2.0. Ænix commercializes it as Ænix Platform as three platforms on one engine — Public Cloud, Private Cloud and AI — that combine rather than exclude each other.
