4,987View on GitHubHelmfile is a declarative tool for managing Kubernetes Helm releases across multiple environments. It defines the desired state of releases in version-controlled YAML files and synchronizes the cluster to match that state, acting as both a release manager and a state sync orchestrator. The tool layers environment-specific values, secrets, and lifecycle hooks onto shared release definitions, enabling consistent multi-environment deployments. Helmfile distinguishes itself through several integrated capabilities: it generates separate dependency lockfiles per environment for staged rollout of ch
Helmfile is a declarative orchestrator for Helm releases that generates Kubernetes YAML manifests through Helm templating, while adding environment-specific layering and state synchronization — fitting the intent for a templating tool with a Helm-like but more declarative approach.

7,522View on GitHubJsonnet is a structured configuration generation language that extends JSON with variables, conditionals, and object-oriented features to create reusable templates. It is designed to eliminate duplication in configuration data by providing a data templating language that can produce structured output from concise, programmable templates. The language distinguishes itself through an object-oriented inheritance model that allows field override, mixin composition, and self-referencing for modular configuration reuse. It supports lazy evaluation with thunks to defer computation until values are f
Jsonnet is a structured config templating language commonly used to generate Kubernetes YAML manifests, offering a declarative, object-oriented approach that serves as an alternative to Helm — it fits the category but lacks direct Helm chart compatibility and built-in Kustomize-style overlays.
