At a glance

Before switching PHP in production, this scanner walks your plugins and themes locally to flag incompatible code — file and line included. Modern fork of WP Engine's abandoned checker, no Tide API: ideal on shared hosting, with 8.3/8.4/8.5 presets and JSON export for agencies.

Full-page real admin UI — presets, diagnostics and detailed settings.

Why scan before switching PHP

The white-screen risk in production, and how this plugin helps you avoid it.

The PHP upgrade risk

One click in the hosting panel can break the whole site if code isn't ready.

Hosting panels make switching PHP versions easy — but incompatible code can white-screen your site instantly.

Removed functions (mysql_*, each, create_function) break on PHP 8.0+
Deprecated APIs flood logs and become errors in later versions
Premium plugins not on WordPress.org are rarely checked by host tools
The abandoned WP Engine checker relied on an external Tide API

The Volade answer

Local scan with file, line and JSON export — no third-party API dependency.

Scan before you switch. Fix errors on staging. Keep warnings on your roadmap.

Bundled PHPCompatibilityWP + smart fallback tokenizer rules
Presets: next PHP, 8.3, 8.4, 8.5, before host migration
AJAX batch scan with progress — no shell access required
Plugin list badges and Site Health test after each scan

5 one-click presets
