SAC Database Inspector is a lightweight, admin-only utility designed to help site administrators understand what is stored in their site’s database and cache — and clean it up safely when needed.
Unlike aggressive “optimizer” plugins, Database Inspector focuses on visibility first, showing you where bloat exists before offering optional, manual cleanup actions.
<h3>Key features:</h3>
<ul>
<li>Database health gauge with clear visual feedback</li>
<li>View total database size (when supported by hosting)</li>
<li>Inspect autoloaded options that load on every page</li>
<li>Identify expired and unused transients</li>
<li>Detect post revisions, auto-drafts, spam, and trash</li>
<li>Find orphaned post meta and comment meta</li>
<li>Flush external object cache (when enabled)</li>
<li>Optional read-only mode via filter for audit-only environments</li>
<li>Multisite-aware and shared-host safe</li>
<li>No frontend impact — admin-only</li>
<li>Contextual source identification for autoloaded options</li>
<li>Full WordPress 7.0 compatibility</li>
</ul>
All cleanup actions require explicit confirmation and are protected by nonces and capability checks.
<h3>Developer Notes</h3>
This plugin follows coding standards and avoids aggressive optimization tactics. It is intended as a transparent inspection and maintenance tool, not an automatic optimizer.
Filters and actions are provided for extensibility.
