Stop guessing what's loading on your site.
Nahnu Asset Scanner scans your front end and builds a precise, attributed inventory of every JS file, CSS file, cookie, and external domain. Configure your cache plugin and cookie consent from real data, not guesswork.
Cache and consent configs are only as good as your data.
Which scripts should you exclude from defer?
Generic guides list common ones. But your site has plugins those guides have never heard of. Deferring the wrong script breaks things, and you won't always know why.
Which cookies actually need consent?
Cookie consent plugins scan your site, but they don't always attribute cookies to the plugin that sets them or categorize them correctly. You end up over-blocking or missing things entirely.
What third-party services is your site calling?
Every plugin can silently phone home to an external domain. Until you look, you have no idea what belongs on your GDPR processor list or what is slowing your site down.
The missing step before you configure anything.
Run a scan first. Then configure your cache plugin and cookie consent from real data, not assumptions.
Cache optimization
See every JS and CSS file loaded on your site: the exact handle, file path, size, and the plugin that registered it. Know what to exclude before you flip a defer setting.
Cookie consent accuracy
Get a categorized cookie inventory from a real scan of your site. Each cookie is labeled Necessary, Preferences, Analytics, or Marketing, with the plugin that sets it already identified.
Third-party auditing
Every external domain your site contacts during a page load, captured and listed in one tab. Use it as the starting point for your Content Security Policy or GDPR processor list.
Three steps. No setup. No account.
The scanner only runs when you click the button. Zero impact on your visitors.
Select your pages
Choose up to 10 pages to include: homepage, shop, checkout, blog. Run multiple scans to cover different sections of your site.
Run the scan
Click Run Scan. The plugin visits each page on your server with no external API calls and no data leaving your site. Results stored in your own database.
