PSP Detector

Chrome extension to detect Payment Service Providers on web pages

PSP Detector identifies the Payment Service Provider (PSP), payment orchestrator, or transaction service provider powering any website in one click. Just visit a checkout page and click the extension icon. PSP Detector scans the page in real time and shows you the provider's logo, a plain-English description, and a direct link to their website. • Real-time detection: Instantly identifies PSPs on the active tab without needing to open DevTools or inspect the page source. • 160+ providers covered: Includes the world's most widely used PSPs, payment orchestrators, and third-party service providers. • Detection evidence: Shows exactly how the provider was identified: which script domain, network request, or HTML pattern triggered the match — so you can verify it yourself. • History dashboard: Browse a searchable, filterable log of every detection across all sites you've visited. Export your full history as a CSV for further analysis. • Provider deep-links: Jump directly to any provider's official website with a single click. How it works: 1. Install PSP Detector. 2. Navigate to any website — ideally a checkout or payment page. 3. Click the PSP Detector icon in your toolbar. 4. See the provider name, logo, description, and website link instantly. Privacy: PSP Detector runs detection entirely on your device and does not send your browsing history, page content, or merchant URLs. It does send limited anonymous usage telemetry (for example event type, extension version, and coarse environment signals) to improve the extension. Suggestions: Have a PSP request, bug report, or feature idea? Open an issue on GitHub or use the "Suggest a PSP" link inside the extension.
