ChartCenter was a free central repository that provided a unified platform for accessing immutable, secure, and reliable Helm charts for Kubernetes applications, offering a single source of truth to proxy public charts from various repositories. This eliminated the need to individually add each chart's repository to the Helm client, streamlining the installation and update process for Kubernetes apps. ChartCenter featured over 30,000 versioned Helm charts and provided rich metadata on dependencies and security, ensuring users always knew the exact nature of the charts they were using. It offered a namespace system to identify the original repositories of the charts, facilitating accurate referencing in dependency charts. The platform also introduced a ChartCenter plugin for Helm, which enabled the Helm client to recognize namespaces and simplified the process of updating and packaging Helm charts using a command that integrated dependency updates and package creation. Despite the benefits, the repository was sunset as of May 1, 2021, and all its features were deprecated, prompting users to consult the Centers deprecation blog post for further information.
