AppRanks verdict
Generated from live marketplace data — refreshed daily
Plugin Compatibility Checker is a well-rated WordPress app with a limited review volume. It is listed in the Security category on WordPress Plugin Directory, which AppRanks treats as the canonical taxonomy node for ranking and competitor comparison. 11 reviews put it in the early-traction tier — useful for early-stage stores willing to be on the leading edge. Early-traction review counts are sensitive to single launch periods or feature events, so a 30-day re-check before bigger commitments often resolves whether the trend is sustained. Paid-only pricing means evaluating fit on the marketplace listing or via the developer's documentation before installing. AppRanks tracks rating, review count, pricing tier, and category position daily — the figures on this page reflect the most recent scrape from the canonical WordPress Plugin Directory listing.

How Plugin Compatibility Checker works
Show full descriptionShow less
The Plugin Compatibility Checker helps you keep your WordPress site stable and secure by scanning installed plugins for PHP, Database, and WordPress version compatibility.
🆕 WordPress 7.0 Database Readiness
WordPress 7.0 introduces stricter database requirements (MySQL 8.0+ / MariaDB 10.6+). Many hosting environments still run older database versions which may silently block updates. This plugin now detects database compatibility and warns you before upgrading.
$1/month License Required (Entry Plan)
You must subscribe to the CompatShield Portal ($1/month recurring) to obtain a license key. Once activated, you will be able to see plugin compatibility results (up to PHP 8.5) and database compatibility directly inside your WordPress admin.
