Thank you for the feedback.
My motivation was to give PR/MR reviewers a very low-friction way to see a Helm chart change running.
The workflow is intentionally simple: install a GitHub App (or call a REST API in other workflows), open a PR/MR, and you get a live preview. That’s it.
There’s no ArgoCD setup, no Helmfile, no cluster provisioning, no DNS wiring to build or maintain. The goal was to make it trivial for reviewers to see “this PR running” — especially for public Helm charts where contributors and reviewers can’t realistically be expected to set up infrastructure just to demo a change.
If you already run ephemeral previews via ArgoCD or Helmfile, this probably isn’t adding much value. Those approaches work well once they’re in place. Chart Preview is aimed at the cases where teams want PR previews without having to design, build, and maintain that machinery themselves.
That makes sense — thanks for clarifying. Framing it as “zero infra ownership, just a reviewer convenience” really helps explain where this fits compared to ArgoCD-style previews.
