ZeroWebTools

A local-first, privacy-respecting browser extension that brings essential developer utilities, API testing, and web reading modes directly into your toolbar. Running fully inside sandboxed browser memory, it processes all data locally without server uploads.

Core features:

1. REST API Client: Test and debug endpoints with custom headers, query params, and methods (GET/POST) directly from your toolbar. The extension automatically bypasses CORS rules, making it a fast alternative to Postman or Insomnia.
2. Smart Article Reader: Extract clean text from cluttered articles. Bypasses distracting layouts and ad blocks, generating a clean, readable print layout (an alternative to Pocket or Mercury Reader).
3. YouTube Transcript Extractor: Download and copy YouTube video subtitles and closed captions as structured transcript text in seconds.
4. Developer Utilities: Packs an interactive JSON formatter tree explorer, side-by-side text Diff checker, JWT decoder, multi-case naming converter, Base64 encoder, and URL percent-encoder.
