Chrome Web Store Extensions Scraper

Chrome extension records — name, rating, install count, version, size, developer and contact email, languages, screenshots, and the complete extension manifest with its permissions.

Why use this actor

• You get the manifest. Every row carries the extension's real manifest.json, parsed, with permissions and host_permissions broken out as lists you can filter on. That is the answer to "which of these extensions can read every page I visit?" — and it comes back even on search results, without opening a single extension page.
• Developer name and contact email on every record.
• Look up as many extensions as you like. Paste ids or store URLs; there is no cap on that path. Search and category pages are limited to their first page by Google itself, and the output says so rather than quietly returning the same ten rows over and over.
• Rounded numbers are labelled as rounded. Google publishes install counts as buckets (20,000,000 — not 20,143,882), so the field is named installCountApprox and flagged. Nobody should build a market-share model on it by accident.
• No account, no API key, no login.

How it works

1. You give it extension ids or URLs, search terms, or category/collection pages.
2. It reads the structured record Google already embeds in each page — no screen-scraping of layout, so a redesign does not break it.
3. For discovered extensions it optionally opens each one's page to add the version, size, languages, developer and long description.
4. Results land in your dataset as JSON, CSV or Excel, with a summary row per query.

Input

{
  "extensionIds": ["ddkjiahejlhfcafbddmgiahcphecmpfh"],
  "searchTerms": ["adblock"],
  "listingUrls": ["https://chromewebstore.google.com/category/extensions/productivity/workflow"],
  "includeDetails": true,
  "includeRawPayload": false,
  "maxItemsPerQuery": 200,
  "maxConcurrency": 4,
  "minRequestInterval": 0.6,
  "proxyConfiguration": { "useApifyProxy": true }
}

Field	Type	Description
extensionIds	array	The 32-letter id from a store URL, or the full URL. The only input with no result cap.
searchTerms	array	Store search. Google serves 10 results per term and no more.
listingUrls	array	A category page (~32 extensions) or collection page (~16). First page only.
includeDetails	boolean	Open each discovered extension's own page for version, size, languages, developer and the long description. One request per extension. Default true.
includeRawPayload	boolean	Attach Google's untouched data array to every row — the only complete copy of what was sent, since the source has no field names. Roughly doubles row size. Default false.
maxItemsPerQuery	integer	Cap per search term or listing URL. 0 = no cap, though Google's first-page limit still applies. Default 200.
maxConcurrency	integer	Requests in flight. Default 4.
minRequestInterval	number	Seconds between request starts. Default 0.6.
proxyConfiguration	object	Apify Proxy. Datacenter is the default and is sufficient.

Output

Three record types share one dataset, told apart by recordType.

}

Field	Description
extensionId / extensionUrl	The id and a direct store link.
name / shortDescription / fullDescription	Listing copy.
rating / ratingCount	Average score and how many ratings it rests on.
installCountApprox	A rounded bucket, not an exact figure.
categoryPath	e.g. make_chrome_yours/privacy.
version / size / minimumChromeVersion	Release detail (detail pass).
developerName / developerEmail	Publisher and contact (detail pass).
firstPublishedAt / lastUpdatedAt	ISO 8601 UTC.
manifest / manifestRaw / manifestVersion	The extension's real manifest, parsed and raw.
permissions / hostPermissions	Pulled out of the manifest so you can filter on them.
languages / languageCodes	Supported locales (detail pass).
iconUrl / bannerUrl / tileUrl / screenshotUrls	Imagery.
websiteUrl / supportUrl / privacyPolicyUrl	Publisher links.
rawCard	Google's untouched array, when includeRawPayload is on.
_detailError	Present only when an extension's own page could not be read.

SEARCH_SUMMARY

Field	Description
surface	detail, search or listing.
requested / extensionsReturned / failures	What the query did.
upstreamServesFixedFirstPage	true for search and listing — Google's own cap, not this actor's.
installCountIsApproximate	Always true.
decodedFromPositionalArray	Always true — see Known limits.

ERROR

_error	Meaning
invalid_input	A malformed extension id, or a URL that is not a Chrome Web Store page.
not_found	The extension page carried no record — removed, unpublished, or a wrong id.
unexpected_shape	The page loaded but the data was not where this actor expects it.
fetch_failed	Network or server trouble after retries.

Known limits

• Search returns 10 results, categories about 32. That is Google's own first-page limit; the store loads more over a private channel this actor does not use. For coverage, feed extension ids directly — that path has no cap.
• Install counts are rounded to public buckets.
• Reviews are not included — only the rating and the number of ratings.
• Google publishes these records without field names, as bare positional arrays. This actor decodes the positions it can justify and leaves the rest untouched; turn on includeRawPayload to see everything that was sent. If Google ever reorders the array, the actor fails with an error rather than reporting wrong numbers.
