Permissions-Policy Checker
Analyze a website's Permissions-Policy header to determine which powerful browser features (like camera, microphone, or geolocation) are explicitly allowed or restricted.

Why use a Permissions-Policy?
The Permissions-Policy header allows a site to control which features and APIs can be used in the browser.
For example, if you embed third-party iframes (like ads or widgets) on your site, they might attempt to use the microphone, camera, or geolocation APIs without your knowledge. Setting a strict Permissions-Policy ensures that these features are blocked entirely, or only allowed for your own origin.
Legacy Syntax
Before it was standardized as Permissions-Policy, this header was known as Feature-Policy. The syntax was slightly different (using semicolons instead of commas, and spaces instead of parentheses). This tool will detect both headers if they exist, but you should migrate to the modern Permissions-Policy syntax.
