What is the Firehose?
The BuiltWith Firehose uses our Internet Real Time Technology Archive Architecture to provide technology lookup results directly to you based on what live websites are currently using. The system is the identical to what BuiltWith uses to power the Pro database and Technology Profiles, the difference being the results of the lookups are pushed to you.
You provide us with a list of website domains you want us to index, we will visit those sites, subdomains and internal pages and provide all technologies in a report back to you.
If you require a non-bulk endpoint for this system please see the Domain Live API.
