Mega Database Cleanup

Mega Database Cleanup is a modern, high-performance cleanup utility built to remove unused, empty, bloated, or orphaned metadata from your WordPress database — safely and automatically.

It includes a smart scanner, preview mode, ACF pattern cleanup, scheduled tasks, and full backup support. Ideal for site owners, developers, agencies, and power users who want a faster & cleaner database without risking important data.

Version 2.0.0 introduces a completely rewritten modular architecture, a real-time Health Dashboard, and targeted cleanup modules for post revisions, trash, spam comments, and expired transients.

Highlights

• Health Score Dashboard Real-time visual representation of your database health and performance at a glance. [NEW in 2.0.0]

• Targeted Cleanup Modules Fast, one-click optimization for Post Revisions, Trashed Content, Spam Comments, and Expired Transients. [NEW in 2.0.0]

• Empty / Unused Meta Scanner Detects empty, null, serialized-empty, or JSON-empty metadata across Post, User, Term, and Comment tables.

• ACF Cleanup Engine Automatically identifies patterns used by Advanced Custom Fields to detect orphan entries.

• Safety Vault System Automatically secures deleted revisions and junk data in a temporary vault for easy recovery. [NEW in 2.0.0]

• Snapshot Management Create manual snapshots of your metadata before cleanup and restore them whenever needed. [NEW in 2.0.0]

• Real-Time Safe Preview See exactly what will be deleted before confirming cleanup.

• Backup Before Delete All removed metadata can be stored in a dedicated backup table / snapshot.

Who Is This For?

Why Mega Database Cleanup Is Different

• Designed for large databases

Privacy Policy

Mega Database Cleanup is committed to transparency regarding user data:

• No external data transmission — No information ever leaves your site.
• Activation popup (optional) — If you enter your email in the welcome popup, it is saved to your site’s wp_options table (mdbcp_subscriber_email). It is never sent to any third-party server. You can skip this step entirely.
• Deactivation feedback (optional) — If you submit a deactivation reason, it is saved locally to your site’s wp_options table (mdbcp_deactivation_log). It is never sent externally. You can skip this step entirely.
• Database backups — Backup data is stored in a dedicated custom table on your own database server.
