Chrome Web Store + Edge Add-ons Extension Intel

Look up any browser extension by ID or store URL and get clean, structured data from both the Chrome Web Store and Microsoft Edge Add-ons: users, rating, rating count, version, last update, size, category, developer, featured badge, EU trader status, and for Edge the full permission list with risk flags. Turn on monitor mode to get alerts when an extension ships a new version, gains or loses users, changes owner, or adds new permissions, the classic sign of a sold or hijacked extension.

Who it's for

• Extension developers: track competitors' installs, ratings and release cadence.
• Security / IT teams: watch the extensions your org allows and get flagged on permission creep or a developer change.
• Investors and acquirers: size extension businesses by install base.

Input

Field	Description
extensions	32-char IDs or store URLs (Chrome or Edge)
stores	Stores to check for bare IDs (default both)
monitorMode / onlyChanged	Diff against the previous run; optionally output only changes
includeDescription	Full description (Edge)

Find extensions by keyword or category

You don't need IDs:

• searchKeywords search Edge Add-ons (the same public search the store site uses). You can add an edgeCategory filter, sort by relevance, rating or installs, and get up to 1,000 hits per keyword.
• chromeCategories (e.g. make_chrome_yours/privacy, productivity/developer) return the Chrome Web Store's listed extensions for each category. If you also give searchKeywords, Chrome rows are filtered to ones whose name or summary contains the keyword. We don't query Chrome's search page, because its robots.txt disallows it.
• Each discovered row carries discovery (source, keyword or category, rank, totalMatches), so you can track search rank over time together with monitor mode.
• Set enrichDetails: false for a fast listing-only pass (name, developer, rating, ratingCount).

{"searchKeywords":["password manager"],"sortBy":"installs","maxResultsPerSearch":50,"chromeCategories":["make_chrome_yours/privacy"]}

Output (one row per extension per store)

{"store":"edge","id":"odfafepnkmbhccpbejgmiehpchacaeak","name":"uBlock Origin","users":14531821,"rating":4.5,"ratingCount":2680,
 "version":"1.75.0","lastUpdated":"2026-09-16","developer":"Raymond Hill (gorhill)","category":"Productivity",
 "permissions":["alarms","contextMenus","privacy","storage","tabs","unlimitedStorage","webNavigation","webRequest","webRequestBlocking"],
 "riskFlags":["tabs","webRequest","webRequestBlocking","all-sites-access"],"changed":false,"changes":{}}

In monitor mode, changes lists each changed field as {from, to}, and addedPermissions lists any new permissions.

Notes and limits

• Only public store listing pages and Edge's public product-details endpoint are read. No login.
• No reviews and no personal data. Developer email, phone and address are deliberately left out. The Chrome store's robots.txt disallows review pages, and we respect that.
• The Chrome Web Store doesn't publish permissions on its listing page, so permissions is null for Chrome rows. Chrome user counts are rounded by Google (e.g. "21,000,000+").
• Extensions that are missing or removed return found: false, which is useful for spotting takedowns.
