About StackPatrol
StackPatrol is a free third-party scanner for European websites. Detect external scripts, cookies, trackers and CDNs on any front page, classify each vendor by region (US, EU, EEA, UK, Switzerland) and discover European alternatives.

I am a computer science graduate currently pursuing a master’s degree in Applied Computer Science. My interest in privacy technology grew during an internship at iConfirm, where I saw how difficult it can be to turn privacy requirements into a clear picture of what a website actually does.
After building several websites and an app, I started StackPatrol to create something practical for the teams responsible for modern websites. The goal is to help agencies, consultants and DPOs see which services load, where data may flow, and how the site behaves before consent, after “Accept all”, and after “Reject all”.
For me, StackPatrol also reflects a broader motivation: contributing to European digital sovereignty by making vendor ownership and European alternatives easier to evaluate. The product provides technical evidence for privacy review, while leaving legal conclusions to the organization’s DPO or legal adviser.
Why we built it
Most websites have no idea what they actually load. Marketing tags, fonts, embeds, CDNs, RUM beacons and analytics pile up, often added by different teams over years. Few people can list them all, and fewer still can say where the data goes.
Existing tools are either heavy compliance suites priced for enterprises, or browser extensions aimed at end-users. We wanted something in between: a fast, free, technical scan that gives a European startup, agency or consultant a clean overview in under a minute.
A vendor list alone is not enough. StackPatrol was built to make consent behavior observable: what happens before a visitor chooses, what appears after acceptance, and what continues after rejection. That evidence helps website owners and their advisers ask better questions and verify changes over time.
What we believe
- Transparency over magic. Our methodology page explains exactly what we measure and how the score is computed.
- Scanning is always free. No account, no credit card, no scan limit. If you find value in the tool, consider upgrading to Pro for scan history and monitoring.
- European alternatives matter. For every common US-owned vendor we surface a curated list of European or independent alternatives, so teams can make informed choices.
- Privacy by default. We don’t track visitors with third-party analytics. Scan results are saved so you can share a report link. If you’re signed in, scans are saved to your personal dashboard for your eyes only.
- Open methodology, not legal advice. StackPatrol is a technical scanner. It does not certify GDPR compliance and it is not a substitute for a privacy lawyer or DPO.
What we are not
- A consent-management platform.
- A GDPR / DSA compliance certification service.
- A pen-testing or security scanner.
- An advisory firm: we have no commercial relationship with any of the vendors we list.
The data behind the directory
The vendor database is hand-curated. Each entry contains the vendor name, country and ownership region, what it does, and curated European alternatives. We add new vendors continuously as we encounter unmatched third-party domains.

How we’re funded
StackPatrol is a paid product. Scanning is always free and unlimited, no account needed. Pro (€39/month) adds a personal scan history dashboard and weekly monitoring for up to 5 sites. Agency Starter (€89/month), Agency (€149/month) and Agency Pro (€299/month) scale up to 10, 30 and 100 monitored sites, with white-label PDF reports on the Agency tiers. A one-time PDF audit report is also available for €79, no subscription needed.
The free tier (no account required) will always exist. We have no commercial relationship with any vendor we list, and we don’t sell scan data.
