Tandem PHP Upgrade Gatekeeper is an update policy and readiness tool for sites preparing a PHP bump.

Most PHP-compatibility plugins ask you to run a full-site scan and read a report. Tandem PHP Upgrade Gatekeeper’s primary job is different:

Set a target PHP version (the version you plan to move to)
Choose an upgrade gate policy — Warn (default), Soft-block (opt-in), or Off
See a readiness inventory of installed plugins and themes
Get a contextual warning when an update looks at-risk for that target
If Soft-block is enabled, pause that update until you click Allow next update (nonce-protected, 30 minutes)

It does not replace staging tests, host PHP tools, or developer-grade PHPCS / PHPCompatibility suites. Heuristics are local guidance only.

What Tandem PHP Upgrade Gatekeeper intentionally is not

Not a Tide / remote scan service
Not a “Run scan giant report” competitor to modern delta scanners
Not a guarantee that production PHP upgrades will succeed

Defaults that respect the admin experience

Gate mode defaults to Warn (updates still succeed; notice only)
Soft-block is opt-in
Theme gating defaults off
WordPress core updates are never gated

Analysis is local (no remote calls, no shell exec). Encoded / non-analyzable packages are marked Unknown. Always verify on staging before changing production PHP.

Privacy Policy

Tandem PHP Upgrade Gatekeeper does not collect, transmit, or sell personal data. It does not phone home. It only reads local plugin/theme PHP files on the site to produce readiness heuristics and update notices. No external service is contacted by this plugin.
