Show HN: Open-source Heroku PaaS alternative

I deploy on a single machine with Docker, as my apps are both small scale and non-critical (people pay for them though). Kubero popped up when I researched how I would do a multi-server setup should the need for High Availability arise. It might flatten the learning curve and drop the operational overhead of Kubernetes enough to push me in this direction.
As for running the cluster myself, I probably would try to run K8s on talos.dev as well.
Congrats on an inspiring project!
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!
