About SaaS Checker JP
SaaS Checker – Detect external SaaS services on any website.
SaaS Checker is a lightweight and privacy-conscious Chrome extension that detects and displays external SaaS (Software as a Service) tools embedded in the websites you visit. Whether you're a digital marketer, IT manager, or privacy-conscious user, this tool helps you understand what third-party tools are running behind the scenes.
🔍 Key Features:
- Real-time Detection: Automatically scans the current website for external SaaS services, analytics, ad platforms, marketing automation tools, and more.
- Categorized Display: Detected services are neatly grouped by category (e.g., Analytics, Ad-Networks, Tag Managers).
- Minimal UI: The extension opens in a compact window for quick, distraction-free access.
- Multilingual Support: Automatically displays the interface in English or Japanese based on your browser language.
- Optional Data Logging: Anonymous logs of scanned URLs and detected SaaS names (category + service name) may be sent to the server only if enabled in settings. No personal data or browsing history is collected.
🛡️ Privacy First
SaaS Checker does not track or store any personal data. By default, anonymous usage data (user ID, scanned URLs, and detected service names) is sent to improve service quality. This behavior can be disabled at any time from the settings screen.
This extension is designed to be simple, transparent, and useful for anyone curious about the SaaS ecosystem used across websites.
