The Chrome Web Store rounds user counts down to the leading digit, so the user line moves in steps. The ratings count is exact and is the better signal of real adoption.
About SaaS API Inspector
SaaS API Inspector helps developers and QA engineers see exactly which APIs a web app is using—without digging through DevTools or guessing from the UI.
What it does
Detects API calls from the active tab (XHR and fetch)
Shows auth type (JWT, Bearer, session, OAuth)
Groups endpoints by category (auth, users, billing, etc.) from the URL
Lists each request with method, path, status, and masked headers
Filters by search, category, and file type (e.g. hide .json, .css, .png)
Exports to OpenAPI (Swagger) or a Postman collection—with your filters applied
Suggests tools based on what it finds (e.g. auth providers, Stripe, monitoring)
Who it’s for
Backend developers, QA, and anyone reverse‑engineering or documenting SaaS APIs. Understand a product’s API surface in minutes instead of hours.
Privacy
Sensitive headers (e.g. Authorization, cookies) are masked. No data is sent off your device. Built for local inspection only.
