## What it is
ChartMuseum is an open-source Helm Chart Repository server written in Go that serves Helm charts and provides an API for uploading, listing, and deleting chart packages. It supports many cloud storage backends including S3, GCS, Azure Blob, and Minio, and can be deployed as a binary or Docker container.

## Use cases
- host a private helm chart repository
- self-host helm charts server
- upload and version helm charts via api
- serve helm charts from s3 or gcs
- set up internal kubernetes chart registry
- manage helm chart lifecycle with upload and delete

## When to choose
- you need a private or on-prem Helm chart repository with upload support
- you want to back your chart repo with cloud object storage like S3, GCS, or Azure Blob
- you need provenance file support for signed charts
- you want a lightweight, easy-to-deploy chart server with Docker support

## When to avoid
- you only need to serve static charts from a plain web server or object storage without an upload API
- you use OCI-based Helm registries instead of classic chart repositories
- you need a full artifact registry covering containers and other package types

## Facets
- artifact type: service
- maturity: active
- function: http-server, api-framework, object-storage, auth, cli
- domain: cloud-computing, self-hosted, developer-tools
- platform: go, windows, self-hosted, cloud
- tags: helm, kubernetes, chart-repository, package-registry, cloud-storage-backends, devops, containers, docker, linux, macos
