The HTTP Permissions-Policy header compute-pressure directive controls access to the Compute Pressure API.
Permissions-Policy: compute-pressure=<allowlist>;<allowlist>A list of origins for which permission is granted to use the feature. See Permissions-Policy > Syntax for more details.
The default allowlist for compute-pressure is self allowing usage in same-origin nested frames but preventing third-party content from using the feature. Workers (dedicated and shared) adhere to the permission policy set by their owning document(s).
Third-party usage can be selectively enabled using the allow attribute on <iframe> elements:
<iframe src="https://example.com" allow="compute-pressure"></iframe>This HTTP response header disables compute pressure completely:
Permissions-Policy: compute-pressure=()
