- The homepage demonstrates a JSON formatter with zero requests sent and says the tools work with the network switched off.
Field notes
The toolkit is organized as a searchable, category-based collection rather than a single multipurpose editor. Its homepage exposes concrete distinctions between related tasks: JWT decoding is not verification, regex testing includes a timeout, and hashing tools use the platform crypto API. A visible JSON example reports seven keys, 181 bytes, and zero requests sent.
