Show HN: Stackdome – An open source self-hostable Railway alternative on K8s
Since Railway getting pwned is getting all the attention right now, I thought now is a good time to showcase what we've been building. Stackdome is a self hosted platform as a service. The idea is to have simplicity of platforms like Railway and Render, but with the ability to run everything on infrastructure you control.
With Stackdome, you can deploy an application from GitHub, connect multiple services visually, add a managed database, create preview environments, and roll back the entire application if a release breaks.
Features:
- First class support for multi-service applications, shown on a canvas in the UI (inspired by Railway). You can edit, wire up, and create resources from the canvas.
- First class support for multiple clusters. Stackdome acts as the hub and places workloads across clusters (hub and spoke).
- Self hostable, fr

om a small VPS to a large k8s cluster.
- Managed Postgres with WAL archiving, HA, backups, and PITR (CNPG underneath).
- A release system for the whole stack. A release targets everything, and you can roll it back if something breaks.
- Source to image, with an in cluster registry (Zot).
- Disposable preview environments, which can also be multi-service.
- Declarative apps via a Stackfile, deployed with the CLI.
Basically, the idea is to package the tooling in the CNCF/cloud-native ecosystem into an opinionated platform, so that developers can get a without being an expert in Kubernetes or a dozen other projects from the CNCF landscape.
