ZeroWebTools Companion

Companion extension for ZeroWebTools. Extract clean articles, test APIs, and run local utilities. 100% private, no tracking.

🚀 VERSION 0.1.2 UPDATE - ZERO WEB TOOLS COMPANION! We’ve evolved from a simple Dev Tools extension into the official ZeroWebTools Companion! This extension acts as a secure local bridge between your browser and our web platform, unlocking powerful new tools like the Smart Article Reader, Advanced API Testers, and cross-origin utilities. 🔒 Privacy Notice regarding new permissions: To unlock these advanced web utilities, Chrome requires us to request "Read and change all your data on all websites" permissions. This permission is strictly used locally as a bridge—allowing our tools to bypass strict browser CORS restrictions to fetch content, test APIs, and extract formatting on your behalf. We are 100% private: we do NOT track, record, or sell your browsing history, and your data never leaves your device. ZeroWebTools is a lightweight, 100% offline developer toolbelt right in your browser toolbar. All data transformations are processed locally in your browser context using client-side JavaScript. No data is ever sent to external servers, ensuring absolute privacy for sensitive credentials, API keys, and code blocks. --------------------------------------------------------------------------------------------------------------------------------------------------------- 🚀 Six Essential Offline Tools in One Popup: 1.
