The BuiltWith API provides technology profiles for websites and shows you the technologies websites have used since we started tracking them.
This historical tracking resource lets you understand the history of a company, has it made the right choices in terms of technology usage, technology versions and hosting over time.
All the information gathered from the API can be used to determine the level of risk a website exposes to your business on many different levels - Will they churn? Have they made poor technology decisions? Did they keep their software up to date? Are they a data security risk?
