Seeing the stack is the easy half.
A technology lookup tells you what a site runs. An audit adds version context, quality signals and findings to investigate. Monitoring helps you follow what changes after that first look.
What comes back
One score out of 100, built from four graded dimensions, with the technologies that pulled it up or down named underneath. Four real audits, frozen as examples - not mock-ups. The same method, run on four live sites, gives anything from 94 down to 31: an end-of-life WordPress is what separates them.

Three tools, three jobs
Each one below describes itself in its own words, quoted from its own site on 6 Sep 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 scoredKnow your stack. Know what needs attention.
A list of technologies is the starting point. AwesomeTechStack puts versions, quality and known security findings into context, so you can decide what to investigate and what to improve.
Start with the website you care about. Your free AwesomeTechStack account includes 3 audits every month: technologies, detected versions, quality signals and an AI-Readiness grade in one report.
Keep that picture current with Stack Watch. Schedule repeat audits for your own sites or your clients' websites, review changes in your workspace and enable email alerts when you want them.
