Psp Detector

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.
• Suggest missing providers — Spotted a PSP that isn't detected yet? Submit it directly from the extension.

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 does not collect, transmit, or store any personal data or browsing history outside your own browser. Detection runs entirely on your device. No accounts, no sign-in, no tracking.
