About this tool
The NovaBlock tracker scanner downloads the HTML of the URL you provide on our servers (no browser plugin needed) and parses every <script>, <iframe>, <img> and <link> reference. Each host is matched against a maintained list of ~120 ad networks, analytics SaaS providers, fingerprinting libraries and consent management platforms.
Trackers that only load after consent prompts or after JavaScript routing won't show up — for a deeper, browser-side audit, install NovaBlock and open the panel on any site.
