Chrome Web Store Scraper: Extension Data, Users & Permissions

Scrape public Chrome Web Store extension data in bulk: paste extension IDs or store URLs, or a category page, and get one clean row per extension with name, users, rating, rating count, version, last updated, created date, category, size, languages, manifest version, permissions, host permissions, website, support and privacy links, and the publisher's company name. Plain HTTP, no browser, no login. No reviews, no reviewer data, no developer email, phone or address. $1.50 per 1,000 extensions. Not-found, failed and invalid items are free.

What does this Chrome Web Store scraper do?

• Reads the public detail page of each extension (chromewebstore.google.com/detail/<id>)
• Accepts 32-letter extension IDs, new store URLs and old chrome.google.com/webstore URLs
• Reads category and collection pages (for example /category/extensions/productivity/workflow) and scrapes the extensions listed there
• Optionally follows the related extensions on each page to map a niche from one seed
• Parses the published manifest: manifest version (MV2 or MV3), permissions, optional permissions, host permissions and content-script match patterns
• Respects robots.txt (never touches /reviews, /search, /support or /privacy pages) and paces itself at about 2 requests per second

Who is it for?

• Extension developers and indie makers: track competitors' users, ratings and release cadence, and find gaps in a category
• Security and IT teams: audit what permissions and site access a list of extensions asks for, and spot MV2 extensions
• Market researchers and investors: size a niche by users and ratings, and see which publishers are companies
• AI agents and automations: stable JSON through the Apify API or MCP, with a predictable price per extension

Quick start

1. Paste extension IDs or store URLs (the form is prefilled with Bitwarden and Google Translate), or a category page URL.
2. Set Max extensions (20 for a quick test).
3. Click Start, then download JSON, CSV or Excel, or read it through the API.

Sample output

From a real run on November 12, 2026:

Extension	Users	Rating	Ratings	Category	Version	Publisher

If an ID has no public listing (removed, unlisted or mistyped), the row has status: "not-found". Invalid inputs and fetch failures get status: "error" with an errorCode and a plain-English errorMessage. None of these are charged.

Example inputs

A list of extensions by ID or URL:

{ "extensions": ["nngceckbapebfimnlniiiahkandclblb", "https://chromewebstore.google.com/detail/google-translate/aapbdbdomjkkjkaonfhkkikfgjllcleb"] }

Everything listed on a category page:

{ "categoryUrls": ["https://chromewebstore.google.com/category/extensions/productivity/workflow"], "maxItems": 50 }

Map a niche from one seed extension (related extensions):

{ "extensions": ["nngceckbapebfimnlniiiahkandclblb"], "includeRelated": true, "maxItems": 40, "includeDescription": false }

Privacy and data we leave out

Listings also carry developer contact details (email, phone, street address) and, for some publishers, personal names. This Actor never reads or outputs them. For publishers who did not declare themselves a business, publisherName is left empty. No reviews or reviewer names are collected.

Is it legal?

The Actor only reads public pages that the Chrome Web Store's robots.txt allows, without logging in, at a gentle pace. Google's Terms of Service prohibit automated access that violates machine-readable instructions such as robots.txt, and this Actor follows them. You are responsible for how you use the data; check the terms that apply to you.
