Chrome Web Store Extension Scraper

Turn a public Chrome Web Store extension ID or detail URL into a structured metadata row for inventory, vendor review, and extension-market research.

Try it now

{
  "extensions": ["cjpalhdlnbpafiamejdnhcphjbkeiagm"]
}

The ID is the current schema prefill and is verified as uBlock Origin in the existing local dataset.

Real output

The row below is copied verbatim from that local dataset.

{
  "extensionId": "cjpalhdlnbpafiamejdnhcphjbkeiagm",
  "name": "uBlock Origin",
  "description": "Finally, an efficient blocker. Easy on CPU and memory.",
  "users": 13000000,
  "rating": 4.7,
  "ratingCount": null,
  "version": null,
  "updated": null,
  "category": "make_chrome_yours",
  "developer": null,
  "icon": "https://lh3.googleusercontent.com/rrgyVBVte7CfjjeTU-rCHDKba7vtq-yn3o8-10p5b6QOj_2VCDAO3VdggV5fUnugbG2eDGPPjoJ9rsiU_tUZBExgLGc=s128-rj-sc0x00ffffff",
  "url": "https://chromewebstore.google.com/detail/cjpalhdlnbpafiamejdnhcphjbkeiagm"
}

The dataset overview uses these fields, in this order:

name	users	rating	ratingCount	version	category	developer	extensionId
uBlock Origin	13000000	4.7	null	null	make_chrome_yours	null	cjpalhdlnbpafiamejdnhcphjbkeiagm

Pricing

PPE event	FREE-tier unit price	FREE-tier list equivalent	Example result cap	Maximum example event charge
extension	$0.002 per extension result	$2.00 per 1,000 extension results	1	$0.0020

The Actor charges the extension event only when it pushes a valid result. The $0.0020 maximum excludes Apify infrastructure costs and is not a demand or revenue guarantee.

Inputs

Field	Required	Accepted format	Default or prefill	Limits and source behavior
extensions	Yes	Non-empty JSON array. Each item can be a bare 32-character lowercase ID using letters a–p, or a full Chrome Web Store detail URL containing that ID.	Console prefill: ["cjpalhdlnbpafiamejdnhcphjbkeiagm"]; no runtime default	The schema does not set a list-length limit. The Actor processes valid IDs one at a time. Invalid items are skipped, and duplicate IDs are not removed before fetching or charging.

A missing or empty extensions array is rejected. A non-empty array containing only invalid values completes with no rows because every item is skipped.

Output fields

Field	Type	Meaning
extensionId	string	Normalized 32-character Chrome Web Store extension ID.
name	string or null	Public listing name.
description	string or null	Public listing description.
users	integer or null	User count parsed from the public listing.
rating	number or null	Average rating parsed from the public listing.
ratingCount	integer or null	Number of ratings when the listing exposes it in a recognized form.
version	string or null	Published version when exposed by the listing.
updated	string or null	Published or updated date when exposed by the listing.
category	string or null	Category slug or application category found on the listing.
developer	string or null	Public developer or author name when exposed by the listing.
icon	string or null	Public listing image URL.
url	string	Canonical Chrome Web Store detail URL built from extensionId.

developer, ratingCount, version, and updated are legitimately nullable. The public page does not always expose those values in markup the Actor can parse; the real uBlock Origin row above shows all four as null. Other schema fields are also nullable where the source can omit them.

Use cases

• Build an inventory of approved or observed extension IDs with canonical Store URLs.
• Snapshot public user counts and ratings for vendor or portfolio review.
• Compare public metadata across competing extensions.
• Feed extension name, category, publisher, and version fields into an internal review workflow without copying page HTML.

Source, coverage, freshness, and responsible use

Google retired the official Chrome Web Store API. This Actor fills that metadata gap by fetching each public extension detail page over HTTP and parsing the listing available at run time. It does not log in, use private account data, or access developer-console fields.

Coverage is limited to public listings that resolve by ID. Unlisted, removed, region-blocked, or temporarily unavailable pages may produce no row. Chrome Web Store markup can change, and some values may remain null even when the page renders other information to a browser. Each run is a current observation; the Actor does not keep a historical index.

Use the output in line with Chrome Web Store terms and applicable law. Treat user counts, ratings, and developer details as public listing claims rather than independently verified facts.

Troubleshooting

• Input rejected: provide a non-empty extensions array.
• Invalid ID or URL: use a 32-character lowercase ID made only from a through p, or a Chrome Web Store detail URL containing one. Invalid items are logged and skipped.
• No row for a valid ID: open the public detail URL and confirm the listing still exists. A 404, removal, regional restriction, temporary HTTP failure, or missing listing name produces no result.
• Fields are null: developer, ratingCount, version, and updated can be absent from the current public markup. A null value is not by itself an invalid-ID signal.
