Hey HN,

I’m Gianni and the creator of Kubero, an open-source PaaS. I've been working on it for the past 3 years and now I've just released version 3. The idea for Kubero was born during Heroku’s major outage in 2022, when I realized how much we rely on closed platforms — and how fragile that can be. The main goal is to keep the workflows and simplicity of Heroku, but with the freedom and control of self-hosting. Developers are empowered to take charge of their infrastructure. No infrastructure hassle — just push your code, and it runs.

Kubero is running on Kubernetes, as an operator. It comes with an intuitive web UI, Accessible API, and a CLI. It supports Dockerfiles, Nixpacks, Runpacks, and Buildpacks for building your applications. You can deploy any containerized app with ease. Or just use the 170+ pre-configured templates to get started quickly. It’s designed to be user-friendly, even for those who aren’t Kubernetes experts.

Core Features:

- Run any docker container with Add-Ons (Postgres, Redis, etc.)

- Git-based deployments (just git push)

- Starting Apps with a pull request

- High availability and autoscaling

- App metrics and logs

- 170+ pre-configured templates for quick setup

- API for automation and integration

- CLI for easy management and installation

- Web-Console and Logs in the UI

- SSL handling with cert manager

...

I’ve also put together a detailed feature comparison with Heroku here: https://www.kubero.dev/docs/comparison-heroku

What’s New in v3:

- Built-in User Management –> Roles, API tokens, permission system.

- Team Views –> Manage multiple teams/projects in one instance.

- Multi-language support (English, German, Japanese, Chinese, Portuguese, ... more to come)

- Tested and Stable –> 500+ Jest tests, ~85% test coverage.

Kubero is 100% open source and welcomes contributors. If you’ve ever wanted more control over your app platform — or just want a break from vendor lock-in — give it a try!

Happy to answer questions and get your feedback!
