Chrome Web Store extension data

• 340,922 extensions — the complete Chrome Web Store, enumerated from all 354,175 listing URLs
• 334,221 with user install counts (98% coverage) — the demand signal, published as exact figures below ~1,000 users and rounded above
• Full manifest per extension — version, requested permissions and host permissions, parsed from the store's own payload. Nothing else in this market ships permission data at catalog scale.
• 144,764 rated, with the full-precision average (4.846153846…, not the rounded 4.8 the store page shows) and the rating count
• Daily rank across 21 collections and categories. Install counts are bucketed, so an extension can triple its users without the number moving — rank is the only fine-grained movement the store exposes.
• 30 categories and 64,598 distinct publishers, with publisher website where the listing declares one
• Install & rating history — a dated observation per crawl, with 14,471 extensions already carrying multiple points. History deepens daily from your purchase date onward.
• CSV, JSONL and Parquet — all three included
• Browse it online — searchable, sortable explorer with per-extension charts, plus the raw files
