How to detect BuiltWith
BuiltWith signs its requests, so you detect it by verifying the cryptographic signature on each request. A valid signature proves the request came from BuiltWith; a copied user agent without the signature does not.

How do you detect BuiltWith?
BuiltWith signs its requests, so you detect it by verifying the cryptographic signature on each request. A valid signature proves the request came from BuiltWith; a copied user agent without the signature does not.
What is BuiltWith?
BuiltWith is an automated service from BuiltWith that signs its requests.
Does BuiltWith identify itself?
Yes. BuiltWith signs its requests cryptographically, which is the strongest way an agent can identify itself.
Can a bot pretend to be BuiltWith?
Not convincingly. A bot can copy BuiltWith's user agent, but without BuiltWith signing keys its requests fail verification and it is not labeled BuiltWith.
How common is BuiltWith?
Very uncommon. Rare, brand new, or not seen on Verisoul traffic yet.
What does the Verisoul API return for BuiltWith?
Every session Verisoul identifies as BuiltWith carries an agent block with id "builtwith", name, provider, type "other", detection_method "signed" and the detection_signals used (cryptographic, behavioral). Build rules on the id, type and detection method.
