Every priced way we found to get BuiltWith's data: the official API, data resellers, marketplace listings and scrapers, ranked by price per 1,000 records. The cheapest route is 500x cheaper than the typical one. Prices are researched from each vendor's own page and dated; a route without a published price stays unpriced.
Cheapest first, by price per 1,000 records at the vendor's best tier. Confidence: stated on the vendor's page, derived from its plan maths, estimated otherwise.
