Permissions-Policy Builder
Compose a Permissions-Policy header from feature + allowlist pairs.
Permissions-Policy:
Tip: an empty allowlist () blocks the feature for everyone, (self) permits only same-origin, and * allows everywhere.
About this tool
Pick features (camera, geolocation, …) and the allowlist for each: empty (disable everywhere), self (your origin only), * (anywhere) or a specific origin.
