ZeroWebTools Companion από Zeeshan Ahmad

ZeroWebTools Companion is a secure browser extension designed to extend the capabilities of the zerowebtools.com platform and bring a lightweight, 100% offline developer toolbelt right into your Firefox toolbar.

All data transformations and formats are executed locally in your browser context. No data is ever sent to external servers, making it a safe choice for corporate developers handling sensitive API credentials, production logs, tokens, or proprietary code blocks.

🚀 Six Essential Offline Utilities in One Popup:

1. JSON Formatter & Tree Explorer: Paste raw JSON to validate it, pretty-print it (with collapsible arrays and objects), or minify it instantly.
2. Side-by-Side Diff Checker: Compare two blocks of code or text files inline to highlight additions, deletions, and line-level changes.
3. JWT Debugger & Decoder: Instantly inspect JSON Web Tokens. Decode headers, payload claims, and signatures securely offline.
4. Case Converter: Transform naming conventions between camelCase, snake_case, kebab-case, and PascalCase.
5. Base64 Cipher: Encode strings to Base64 or decode hashes back to readable plain text.
6. URL Encoder/Decoder: Clean percent-encoding from URL parameter strings and format query parameters.

🔗 Secure Platform Bridge for Advanced Tools:

Unlocks advanced capabilities on zerowebtools.com by routing permissions securely through your local browser context:
- CORS Bypass: Execute requests in the online REST API Client directly from your local browser context, eliminating the need for proxy servers.
- Local Web Scraping: Extracts clean text nodes locally for the Smart Article Reader and YouTube Transcriber without intermediate database logging.

🔒 Privacy-First Design:

• Runs completely offline in your browser's sandbox memory.
• Zero telemetry, tracking scripts, or analytical cookies.
• Zero server communication.
