Chart Preview – Ephemeral Helm chart environments for every pull request

Summary: Chart Preview automatically deploys Helm charts from GitHub or GitLab pull requests to isolated Kubernetes environments, providing live preview URLs without requiring cluster management. It updates previews on code pushes and cleans up environments when PRs close, integrating status checks and deployment logs.

What it does

It creates temporary Kubernetes environments for each PR by deploying Helm charts from Git, OCI, or TGZ sources. The tool connects to repositories and manages previews with automatic updates and cleanup, handling Helm-specific workflows like chart dependencies and layered values.

Who it's for

Developers and teams working with Helm charts who need automated, isolated preview environments for pull request testing without manual cluster setup.

Why it matters

It eliminates delays caused by manual environment setup and reduces bottlenecks by enabling reviewers to access live previews directly from PRs.
