Chrome Web Store Scraper

Scrape Chrome extensions from the Chrome Web Store. Pull comprehensive extension metadata — name, rating, review count, user count, version, full manifest, permissions, category, developer info, screenshots, and website URL. Search by keyword or provide specific extension IDs.

Features

  • Three input modes: by extension ID, by URL, or by search query
  • Rich data extraction: 25 fields per extension including the full parsed manifest.json
  • No proxy needed: Chrome Web Store serves to datacenter IPs cleanly
  • Fast extraction: Data is embedded server-side in the HTML — no JavaScript rendering required
  • Permissions analysis: Extracts permissions array from the manifest for security audits

Use Cases

  • Extension research and competitive analysis
  • Security auditing — identify extensions with broad permissions (<all_urls>, webRequest, etc.)
  • Developer directory building
  • Chrome extension market research and trend tracking
  • Finding extensions by category or keyword

Input Configuration

Field Type Description
extensionIds Array List of extension IDs (32-char alphanumeric) to scrape directly
startUrls Array Chrome Web Store URLs (detail pages, search pages, or category pages)
searchQuery String Search term to find extensions (e.g. "password manager", "ad blocker")
maxItems Integer Maximum number of records to return (0 = unlimited, default 20)

Provide one of extensionIds, startUrls, or searchQuery. If none are provided, the actor runs a default search for "productivity".

Example: Scrape by Extension ID

{
    "extensionIds": ["cjpalhdlnbpafiamejdnhcphjbkeiagm"],
    "maxItems": 1
}

Example: Search by Keyword

{
    "searchQuery": "password manager",
    "maxItems": 20
}

Example: Specific Store URLs

{
    "startUrls": [
        "https://chromewebstore.google.com/detail/ublock-origin/cjpalhdlnbpafiamejdnhcphjbkeiagm",
        "https://chromewebstore.google.com/search/vpn"
    ],
    "maxItems": 50
}

Technical Notes

  • Data is extracted from server-rendered AF_initDataCallback script blocks — no browser rendering needed
  • core_crawler (CheerioCrawler) with concurrency 3 to respect Google rate limits
  • No proxy required — datacenter IPs work fine
  • Memory: 512 MB is sufficient for most runs
  • Timeout: 4 hours default (plenty for bulk runs)
