Technical Specifications & Privacy Guarantee

No plain text, uploaded media, or API tokens are transmitted over the internet or logged into remote server infrastructure.
Common Practical Use Cases
- API Debugging: expand a deeply nested webhook payload one level at a time instead of scrolling raw text.
- Backend Development: search for a key name and read back the dotted paths that contain it, like author.email.
- QA Engineering: collapse large arrays to a '...12 items' summary so the surrounding structure stays on screen.
- Technical Support: paste a customer's config blob and switch to Raw view to copy it back re-indented.
