AI Analysis

●●SolidSolve My ProblemShip It

One-command CRX download when Chrome Web Store has no download button.

Strengths
  • Zero-dependency core handles CRX signature stripping without external libraries.
  • Built-in audit mode scores permissions and network endpoints before install.
  • Works with Chrome Web Store, Edge Add-ons, and bare extension IDs.
Weaknesses
  • CRX downloaders already exist (CRX Viewer, various npm packages) — not novel.
  • Deobfuscation depends on webcrack, which struggles with heavily obfuscated code.
Target Audience

Security researchers, developers auditing extensions, AI agent users
