Verify that your website’s consent setup works
See what loads before consent, after “Accept all”, and after “Reject all”. Get the technical evidence, compare it with the site’s policies, and monitor what changes.
Who StackPatrol is for
Built for European agencies, privacy consultants and DPOs — and the multi-site teams they answer to.
Digital & marketing agencies
Run tracking, analytics and cookie consent across 10–100 client sites. Audit in minutes, propose European alternatives, and turn one-off reviews into monitored retainers.
Privacy consultants
The technical findings and evidence you need before the legal review — vendors by region, cross-border transfers, and the disclosure gaps a policy forgot to name.
External DPOs
Documentation you can stand behind: what loads before consent, who is US-owned, and where the cookie policy and reality diverge.
Multi-site companies
Mid-sized organisations keeping every site consistent from one dashboard, with weekly monitoring and change alerts.
Multi-brand & multi-market teams
Compare vendor stacks and consent behaviour across brands, domains and countries in one place.
In-house privacy & marketing
A living map of the third parties across your web estate — shared by legal, marketing and IT.
Most websites don't know what they're loading
The average page makes requests to dozens of third-party domains. Few teams can list them all.
Hidden dependencies
Marketing tags, fonts, embeds and CDNs pile up, often without anyone keeping track.
Unclear data flows
It's hard to know which vendors are US-owned, EU-based, or somewhere in between.
No simple overview
StackPatrol gives you a clean, technical map of your front-page vendor footprint.
How it works
Paste a URL. We do the rest.
Enter your URL
Paste any public website address. No account needed.
We scan two pages for free
Headless Chromium loads your front page and one additional internal page, recording every request.
Get a region-aware report
Vendors classified by region with EU Independence Score and European alternatives.
What you get
A clean, shareable report built for technical teams. The vendor map is free — no signup. Consent Assurance findings come with a paid plan.
See what loads before consent
The single most decision-relevant signal for a DPO: which advertising, analytics and tracking vendors fire on the very first page load — before the visitor ever answers the cookie banner. First-party services are separated out so the headline count reflects only third-party trackers. A plain-language finding, not a legal verdict.
Test “Reject all”
We click Reject all, then watch the network and name every tracker that keeps firing.
Find the vendors your policy forgot
We compare what your cookie and privacy policies name against what the page actually loads. Free scans show the count; paid plans reveal the vendors.
Map vendors by region
US, EU, EEA, UK or Unknown for every vendor found — with curated European alternatives.
From one free scan to a recurring audit business
Most users start with a free scan, then turn it into an ongoing workflow. Here's the path.
Scan it free
Paste any URL. We crawl 2 pages with a real browser and return a full vendor map in under a minute. No signup.
Monitor weekly
Pro turns the scan into weekly re-checks with email alerts, a durable vendor timeline with first-seen dates, privacy-policy change tracking and an automatic post-consent pass that catches trackers loading only after the cookie banner. Find out the same day a new tracker appears on your site.
Document it
Order a 20-page PDF audit you can hand to your DPO, your board or your client. Branded versions included on Agency plans.
Sell it as a service
Audit up to 100 client sites, run white-label PDFs under your own brand, and turn one-off audits into a monthly retainer.

A note on this report
StackPatrol is the technical map your DPO needs before the legal review. It surfaces the third-party services your site loads and where those vendors are based, so the legal analysis starts from facts, not guesswork.
What we provide is a technical signal: ownership region, observed network requests, vendor metadata. Legal applicability— whether a specific vendor or data flow is lawful for your use case — depends on your contracts, DPAs, sub-processors, data categories, and legal basis. We don’t give legal advice.
