Open any page and ScriptDrag names every third-party script on it — Google Tag Manager, that chat widget, the ad network — with its weight, an estimated main-thread cost, and a kill-list of what to defer or drop. One click. No DevTools, no Lighthouse run, no setup.

ScriptDrag turns anonymous domains into named vendors and a ranked to-do list.
Names every third-party script — Google Tag Manager, Intercom, Doubleclick — with its category, instead of anonymous domains.

Flags when you ship 3 analytics tools or 2 chat widgets — the bloat you can cut today. (Pro)
