Gaps flagged
Verdict
Legacy WordPress stack with tracking that never moved to GA4 and an unenforced email domain. Serviceable today, but leaking data and exposed on deliverability.
So pitch: tracking cleanup + GA4 migration as the entry engagement.
BuiltWith sees an empty page. You see the whole stack.
Modern sites are React and Next.js SPAs. Scrapers hit them and get a blank shell — so BuiltWith and Wappalyzer fall back on stale job-post stacks and self-reported junk. Your discovery starts on wrong assumptions.
TechSpy reads the live footprint: JS-runtime fingerprints, HTTP headers, the tools that only show up after render.
Deep Scan (headless render + HAR) surfaces hidden APIs and SDKs. Interact mode clicks and fills to catch tools that load after interaction. Both take a few minutes, not seconds — worth it when the instant scan isn't enough.

Every signal is a scoped project
What the scan finds maps straight to something you can quote. No leap required.
Turn a one-off audit into a monthly line item
Save the first scan as a baseline. Re-scan monthly and the compare view shows exactly what changed in their stack.
That drift is your standing meeting: new tool they bolted on, tracking that broke, a plugin that went stale. Export a branded PDF for the review.
One audit becomes a technical retainer.
Who this is for
Honest filter. Read it after you've seen the output above.
For
- Web/RevOps/growth/SEO/analytics agencies who sell on discovery quality
- Teams running pre-call audits and monthly technical reviews
Not for
- Anyone wanting a raw tech-list export with no analysis
- One-off curiosity lookups

Zapier and API on the Max plan. This is the part that makes pre-call audits repeatable across the whole team instead of a thing one person does when they remember.
