Seeing the stack is the easy half.
A technology lookup tells you what a site runs. An audit tells you whether it is current, whether it is exposed, and whether anyone would notice if it changed.
What comes back
One score out of 100, built from four graded dimensions, with the technologies that pulled it up or down named underneath. This is a real audit, frozen as an example - not a mock-up.
Three tools, three jobs
Each one below describes itself in its own words, quoted from its own site on 18 Aug 2026. We do not rate the other two - they are built for a different job, and their own pages say so better than we could.
“Find out what websites are Built With”
Every paid plan lists CRM Integration; the plans page says BuiltWith is “free to use for individual site lookups forever”.
“Built for teams that act on technology signals”
Its pricing table sells lead lists, technology lookups, email verifications and CRM enrichment. A free account gets 50 lookups a month.
“Every stack has a score.”
Technology, version currency, engineering quality and AI-readiness, graded and weighted into one number - then re-run on a schedule, so a change finds you instead of the other way round.
how it is scoredWhich one you want
Building prospect lists, or enriching a CRM? That is what BuiltWith and Wappalyzer are built for, and this is not it.
Just want to see what one site runs, once? Both answer that without an account. So does a browser extension.
Need to know whether that stack is current, exposed and worth trusting - and to hear about it when it moves? That is this.
What it costs
3 audits a month are free, for good. Watching sites and the API start at $15 a month on the paid plans. See the plans
