## What it is
PrivacyTests is an open-source testing program that runs automated privacy audits against popular web browsers, measuring leaks like state partitioning and fingerprinting. It includes the test suite, an Express-based test server, and rendering code for the privacytests.org results website.

## Use cases
- compare privacy protections across desktop and mobile browsers
- audit whether a browser leaks tracking state across sites
- check how a nightly browser build handles fingerprinting
- run automated browser privacy tests locally
- publish or render browser privacy test results as a website

## When to choose
- you want unbiased, reproducible measurements of browser privacy behavior
- you are a browser developer verifying privacy fixes in nightly builds
- you need raw test data to analyze tracking protections across browsers

## When to avoid
- you need a general-purpose web security or penetration-testing scanner
- you want a one-click privacy hardening tool rather than measurement
- you need mobile app privacy testing outside of web browsers

## Facets
- artifact type: application
- maturity: active
- function: testing, browser-extension, developer-tools, data-visualization
- domain: privacy, browser-extensions, security, web-development
- platform: cross-platform
- tags: browser-privacy, privacy-tests, browser-fingerprinting, tracking-protection, open-data, web, nodejs
