Prove your app doesn't leak

Every site quietly hands visitor data to third parties. See exactly who yours talks to. Paste a URL and scan it in seconds.

Scan your own sites. Static scan of one public page, see the limits below.

How it works

1. Scan

We fetch your page and find every third party it references, analytics, advertising, social, session-replay, fonts, CDNs.

2. Grade

A to F. Grade A means zero third-party egress, the visitor's browser only ever talked to you.

3. Certify (paid)

Get a signed, tamper-evident proof you stayed clean, monitored continuously, with a dated audit trail.

We collect nothing about your scans. Scan only sites you own or have permission to test.

The name: Provae, from "prove." See what your site leaks, then prove it's clean.
