Overview

Packscope is an open-source Node CLI that turns a single shipped JavaScript bundle — from webpack, rspack, rollup, esbuild, or Vite — into a navigable, executable module tree.

What You Can Do

• Inspect — every module becomes its own file with real boundaries
• Run — the unpacked tree executes identically to the original bundle
• Edit & Rebuild — patch any module and regenerate the bundle
• Unpack from URLs — download, resolve chunks, and rewrite imports
• DevTools Overrides — mirror paths for Chrome Local Overrides
