Helm Repo Index Extractor

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.

Quick start (3 rows, about $0.0015)

Paste this into the Input tab (JSON view) and click Start:

{
  "indexUrl": "https://charts.jetstack.io/index.yaml",
  "chartFilter": "cert-manager",
  "maxRecords": 3
}

You get the three newest cert-manager chart versions. Always set maxRecords when you try a new repository: the Jetstack index holds 412 chart versions and the Prometheus Community index holds 4,273 (counted 2026-09-25).

Output preview (real local run, 2026-09-25)

chart	version	appVersion	created	kubeVersion	chartUrl
cert-manager	v1.21.2	v1.21.2	2026-09-11T06:54:32Z	>= 1.22.0-0	https://charts.jetstack.io/charts/cert-manager-v1.21.2.tgz
cert-manager	v1.21.1	v1.21.1	2026-07-29T14:46:40Z	>= 1.22.0-0	https://charts.jetstack.io/charts/cert-manager-v1.21.1.tgz
cert-manager	v1.21.0	v1.21.0	2026-07-08T22:06:31Z	>= 1.22.0-0	https://charts.jetstack.io/charts/cert-manager-v1.21.0.tgz

Each row also carries digest, dependencies, maintainers, annotations, _raw and totals (_chartCount 7, _versionCount 412, _chartVersionCount 235 for cert-manager in this run), so you can see how big a full harvest would be before you raise the cap.

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

{
  "indexUrl": "https://charts.jetstack.io/index.yaml",
  "chartFilter": "cert-manager",
  "maxRecords": 25
}

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 maxRecords and/or chartFilter to 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 simply null.
• Honest failure: if the URL doesn't return a Helm repository index (an HTML error page, a 404, or YAML without an entries map) 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. If a run emits nothing (bad URL, no matching charts), you pay no chart events.

Run	Rows	FREE-tier event cost ($0.0005/row)
Quick start above	3	$0.0015
Default cap (field left at 8)	8	$0.004
All Jetstack versions (cap cleared)	412	~$0.21
All Prometheus Community versions (cap cleared)	4,273	~$2.14

Paid Apify plans get lower per-row prices through the tiered discount. These figures cover event charges only, not Apify platform compute, and repository sizes change over time.

If you set a maximum cost per run, the Actor checks it before downloading the index, and again before each batch of rows. It stops once another row would not fit. You get only the rows you paid for, and a failed charge fails the run.
