The smart WordPress Code Unloader for faster pages
Code Unloader gives WordPress administrators surgical control over which JavaScript and CSS assets load on each individual page — using exact URL, wildcard, or regex rules.
Easily group unloaded assets and export rules for future use.
Keep your website bloat-free and fast.
Features
Precise control. Zero bloat.
Every feature in the Code Unloader plugin is designed to give you control without complexity. Advanced, lightweight, free to use, and powerful solution with one task only — unload bloat from your WordPress pages. And all of that in a <300 KB package unpacked.
Per-URL Asset Rules
Exact, wildcard (/shop/*), and regex URL matching. Rules survive cache flushes and plugin reactivations.
Frontend Panel
Slide-in panel from Admin Toolbar. Open on any page with ?wpcu — even on pages that hide the toolbar.
Kill Switch
Emergency one-click recovery that bypasses all rules sitewide. Your rules are preserved, just paused.
Device-Type Rules
Target desktop-only or mobile-only asset loading. Serve exactly what each device needs.
Rule Groups
Organise rules into named groups. Enable or disable an entire group at once — no page reload needed.
Full Audit Log
Every rule change is logged. Export and import all rules as clean JSON for backup or migration.
Inline Script Blocking
Detect inline <script> and <style> tags not registered through WordPress’s enqueue system.
Conditional Rules
Rules for logged-in users, WooCommerce pages, specific shortcodes, or post types.
Live Size Tracking
See exact KB unloaded per URL in the stats bar. Instantly know the real impact of every rule.
How It Works
Up and running in minutes
No PHP, no child theme edits. Just the Admin Toolbar and a toggle switch.

See every asset
JS and CSS files listed by plugin, theme, or WordPress Core — with file sizes
Toggle to disable
Set scope, match type, device target, and conditions in the rule dialog
Rules stored in database
Saved in a custom DB table — unaffected by cache flushes or plugin updates
Easily revert changes

Compatibility
Works with your entire stack
Code Unloader operates at the WordPress enqueue layer — before caching, CDNs, or page builders ever see the request. It coexists cleanly with every major performance plugin.
Warning — unloading assets can break your website functionality or visuals!
Although you can easily revert changes made by Code Unloader, it’s prudent to test it on the stage area first. Use Code Unloader at your own risk.

FAQ
Frequently asked questions
Answers to common questions about the Code Unloader WordPress plugin.
Will rules survive a cache flush?
Yes. Rules are stored in a custom database table and are completely unaffected by caching plugin cache clears or plugin reactivations.
What does the kill switch do?
It’s a one-click emergency recovery in Settings. When active, all rules are bypassed sitewide — assets load normally. Your rules are not deleted; they resume when you deactivate it.
What are Rule Groups and how do they help?
Rule Groups let you organise related rules under a single name. You can enable or disable an entire group at once from both the admin screen and the frontend panel. Groups can also be assigned during rule creation, so new rules are automatically organised on save.
Can I export and import my rules?
Yes. Full JSON export and import of all rules, including group assignments. On import, existing groups are matched by name to avoid duplicates, and all rule-to-group links are preserved automatically.
Does it support regex URL matching?
Yes. Choose Regular Expression as the match type when creating a rule. Patterns are validated before saving, with a warning to help you keep them specific.
What PHP version is required?
PHP 8.0 or higher. The plugin uses modern PHP features (union types, match expressions) that are not available in PHP 7.x.
