The technology stack behind any website: analytics, hosting, frameworks and who uses them.
Websites seen at one network address or carrying one BuiltWith tag, with the window each was observed. Supply the address in the provider's own form, such as IP-151.101.1.195, or a tag string; a domain is not a valid input here and returns nothing. Neighbours at an address, not the components a site runs.
Candidate websites for a business name via BuiltWith: each row carries the domain, the company name BuiltWith holds for it, estimated annual technology spend, page rank and any social profiles. The match is fuzzy, so an unrecognised name returns the nearest businesses rather than nothing — read the returned company name before trusting a row. Supply the business name.
Other domains that share an identifier with a site — the same analytics id, advertising id or hosting trace — with the value that ties them together and the window each pairing was seen. Evidence of common ownership or operation, not a redirect and not a link. Supply a domain.
Which domains forward to a site and where that site forwards on, from the BuiltWith index: each entry carries the other domain and the dates the forwarding was first and last observed. Supply a domain; a site involved in no forwarding returns empty lists at no charge.
BuiltWith's verdict on whether a site looks legitimate to transact with: a level, a written summary of what drove it, and the signals behind it such as affiliate links or a missing live record. Every domain gets a verdict — an unknown site is assessed as unverified, which is an answer rather than a blank. Supply a domain.
The vocabulary BuiltWith collected off one website's own pages: the recurring words a site uses to describe itself. These are the site's own wording, not search queries and not ranking data. Supply a domain; a site with nothing collected comes back empty and costs nothing.
BuiltWith adoption coverage for one named stack component, including live and historical website counts and coverage among high-ranked websites.
Free BuiltWith overview for one domain: how many components sit in each group such as framework, hosting, analytics or commerce, with live and retired counts and the dates the website was first and last indexed. Counts by group only, never the component names themselves. Supply a domain.
Components BuiltWith suggests for one website, inferred from what comparable websites run: each row names the suggestion, its category, a link and how established it is. Suggestions for a website, not a description of what the website already runs. Supply a domain; a website with no suggestions returns an empty list at no charge.
Websites currently running a named component, from the BuiltWith index: one row per site with the dates it was first and last detected, plus an opaque cursor for the next page. Supply the exact component name — an unknown name is refused rather than guessed at. Flat price per page with no plan.
Turns a plain description into the canonical component names BuiltWith uses, each with a similarity score, its category and a description — the lookup that makes an adopter list possible when you only know what a tool does. Supply the description. A meaningless phrase still returns the nearest names at low scores, so read the score.
BuiltWith technographics for one domain: detected CMS, hosting, commerce, analytics and other stack components, with first and last detection dates.
