Massoftind Asset Manager helps developers inspect every CSS and JavaScript asset loaded on the frontend, then optimize loading without breaking the site.

Features

Asset scanner (admin bar + timed 15-minute scan sessions)
Page reports with size, dependencies, duplicates, and unused handles
Assets grouped by WordPress core, plugin, theme, must-use plugin, or external source
Search assets by handle, source URL, plugin/theme name, or dependencies
Select all, or select an entire plugin/theme group
Bulk optimize: Disable, Enable (only on selected scope), Async, Defer, Delay
Scopes: entire site, this page/post, all singles, post type, taxonomy archive, URL contains
Current-rule badges on each asset (with link to manage rules)
Dependency viewer and disable simulation
History snapshots with one-click rollback
REST API and WP-CLI for users with manage_options
Debug mode and activity logs
Optional full data cleanup on uninstall

Safety first

Before disabling an asset, the plugin can simulate the change, warn about dependents, and refuse to unload required dependencies at runtime. Core WordPress assets are protected by default. Every rule change can be rolled back.

Privacy

This plugin does not phone home. There is no telemetry, analytics, license check, or remote API call. Everything works offline.

Requirements

WordPress 6.5 or higher
PHP 8.1 or higher
