Block Weight Inspector vs Nahnu Asset Scanner

Block Weight Inspector adds a sidebar panel in the block editor that maps blocks in the current post/page to the CSS and JS assets they register. It estimates local asset sizes, highlights top offenders, and exports a JSON report. It can also generate a suggested conditional-loading snippet to help you dequeue assets when a block is not present. It also adds a Tools -> Block Weight Inspector screen for auditing existing posts without opening the editor. Note: The inspector preserves block comment delimiters when analyzing content so parse_blocks() remains accurate after sanitization. Key features: Block -> asset mapping using registered block metadata. Estimated size for local assets. Top offenders summary and full asset list. JSON export for sharing or auditing. Suggested conditional-loading rules (review before use).

Nahnu Asset Scanner manually scans the pages you choose and builds a complete inventory of everything loaded on your site’s front end. Instead of guessing which scripts to defer or which cookies need a consent banner, you get a precise, plugin-attributed list to work from. What it scans JavaScript — every script, inline or external, with file path, size, whether it’s first- or third-party, and which plugin or theme registered it CSS — every stylesheet with the same attribution detail Cookies — every cookie set during page load, categorized as Necessary / Preferences / Analytics / Marketing, with the plugin that sets it identified from a bundled database of 600+ known cookie patterns covering 400+ plugins Domains — every third-party domain contacted, identified by category using the bundled vendor map Why it matters Cache configuration — cache plugins need to know which cookies bypass the cache (WooCommerce cart, WPML language, login cookies) and which JS/CSS files to exclude from minification or combination. This plugin gives you those exact file paths and cookie names from a real scan of your site, not a generic list. Cookie consent — before configuring Complianz, CookieYes, or Real Cookie Banner, run a scan to get an accurate, categorized cookie inventory. The bundled database covers WooCommerce, membership plugins, LMS platforms, builders, security plugins, analytics services, ad networks, chat widgets, and more. Performance auditing — identify render-blocking scripts, bloated third-party embeds, and unnecessary tracking pixels. The JS and CSS tabs show inline vs. external, first-party vs. third-party, and file size at a glance. Third-party auditing — the Domains tab reveals every external service your site contacts. Use it as the starting point for a Content Security Policy or to assess your GDPR third-party processor list.
