A package manager for Kubernetes that streamlines installing, managing, and sharing applications as Helm Charts.
Helm is a package manager for Kubernetes that simplifies the deployment and management of applications. It allows users to define, install, and upgrade Kubernetes applications using reusable packages called Charts, which bundle all necessary resources and configurations. Helm solves the complexity of managing multiple Kubernetes manifests by providing templating, versioning, and release tracking.
Kubernetes administrators, DevOps engineers, and developers who need to deploy and manage applications on Kubernetes clusters efficiently.
Developers choose Helm because it standardizes Kubernetes application deployments, enables easy sharing and reuse of configurations through Charts, and provides robust lifecycle management for releases. Its templating system and integration with the Kubernetes API streamline complex deployments.

Helm Charts provide a consistent way to package Kubernetes applications, enabling easy sharing and reuse, as evidenced by the extensive library on ArtifactHub.
Helm's template engine dynamically generates Kubernetes manifests, reducing duplication and allowing environment-specific configurations, which simplifies complex deployments.
Helm tracks installations and upgrades as releases, offering built-in version control and rollback capabilities essential for CI/CD pipelines.
With support for various package managers and a large community, Helm integrates seamlessly into diverse workflows, from local development to production environments.
The README highlights that Helm v4 is under active development with unstable APIs, leading to potential breaking changes and migration headaches.
Helm maintains release state in the cluster, which can conflict with GitOps tools that prefer source-controlled, stateless deployments.
Mastering Helm requires understanding Charts, Templates, and Releases, adding complexity for teams new to Kubernetes orchestration.
