How to Audit Third-Party Scripts with Copilot
Find performance-heavy scripts in your IDE with Copilot and ToolRouter. Clean up third-party bloat.
Tool
Copilot identifies performance-heavy third-party scripts and links them to the exact script tags in your code. See which analytics, chat, or advertising scripts slow your pages, then implement lazy loading, defer attributes, or conditional loading directly in your templates without leaving the IDE.

- Re-audit to measure the improvement
Example Prompt
Try this with Copilot using the Lighthouse Audit tool
Find third-party scripts on mysite.com that hurt performance. Update my code to defer-load the heaviest ones.
Tips
- Copilot can wrap scripts in intersection observer patterns for lazy loading
- Great for converting synchronous script tags to dynamic imports
- Search your codebase for script tags Copilot should optimize
