Informazions su la estension
ZeroWebTools is a lightweight, 100% offline developer toolbelt right in your Firefox toolbar.

All data transformations and formats are executed locally in your browser context using WebAssembly and client-side JavaScript. 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.

🔒 Privacy-First Design:
  • Runs completely offline in your browser's sandbox memory.
  • Zero telemetry, tracking scripts, or analytical cookies.
  • Zero server communication.
