Point at any Helm chart repository's index.yaml and get one clean,
structured row per chart version — the entire repository catalogue as a flat
dataset you can filter, diff, inventory, or feed into an SBOM / supply-chain
pipeline.
Every Helm repository — Prometheus Community,
Grafana,
Jetstack / cert-manager,
Bitnami,
HashiCorp,
ingress-nginx,
and the tens of thousands of self-hosted and GitHub-Pages-hosted repos — publishes
the identical Helm repository index standard. So this one actor works against
all of them. No per-repo scraper, no host enumeration: give it an index.yaml
URL and it returns the whole catalogue.
What you get
One dataset row per chart version, with every standard Helm index field
flattened and safely nullable (a repo that omits a field simply yields null):
| Field | Description |
|---|---|
chart / name | Chart name |
version | Chart version (SemVer) — one row each |
appVersion | Version of the app the chart deploys |
chartApiVersion | Chart schema (v1 / v2) |
chartType | application or library |
created | Publish timestamp (ISO-8601) |
digest | SHA-256 digest of the packaged chart |
description | Chart description |
deprecated | Whether the version is deprecated |
kubeVersion | Compatible Kubernetes version range |
home / icon | Project home URL / icon URL |
chartUrl | Direct, absolute download URL of the .tgz (relative repo URLs resolved for you) |
urls | Raw download URL list |
sources | Source-code repository URLs |
keywords | Chart keywords |
dependencies | Sub-chart dependencies (name, version, repository, condition, …) |
maintainers | Maintainers (name, email, url) |
annotations | Chart annotations (e.g. ArtifactHub metadata) |
_raw | The lossless original version entry |
_source, _chartCount, _versionCount, _chartVersionCount | Provenance & totals |
Input
| Field | Required | Description |
|---|---|---|
indexUrl | ✅ | URL of a Helm repository index.yaml. Redirects are followed. |
chartFilter | Case-insensitive substring; only matching chart names are emitted. | |
maxRecords | Global cap on emitted rows (each row = one chart version). | |
bearer | Bearer token for a private/gated repo. Never logged. | |
extraHeaders | Extra request headers (JSON object) for gated repos. Never logged. |
Example
Notes
- Large repos: a single popular chart can have hundreds of releases (Bitnami's
index is tens of MB and holds thousands of versions). Use
maxRecordsand/orchartFilterto scope a run; charts are processed in sorted name order so a capped run is deterministic. - Robust by design: fields are read by key presence, so a repository that
omits
appVersion,dependencies,maintainers,type, etc. never breaks the run — the missing column is simplynull. - Honest failure: if the URL doesn't return a Helm repository index (an HTML
error page, a 404, or YAML without an
entriesmap) the run fails fast rather than emitting empty rows.
Pricing
Pay-per-event: one chart charge per emitted chart-version row. You only pay
for the rows you extract.
