Hackolade is a visual editor for JSON documents for non-programmers.  It is ideal to perform the upfront design and documentation of RESTful APIs.  


Hackolade was specially adapted to support the data modeling of plain JSON files and REST APIs.


Representational state transfer (REST) or RESTful Web services are one way of providing interoperability between computer systems on the Internet. REST-compliant Web services allow requesting systems to access and manipulate textual representations of Web resources using a uniform and predefined set of stateless operations.


JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate.  It is based on a subset of the JavaScript Programming Language.  JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages.  These properties make JSON an ideal data-interchange language.  JSON is built on two structures:

  • A collection of name/value pairs. In various languages, this is realized as an object, record, struct, dictionary, hash table, keyed list, or associative array.
  • An ordered list of values. In most languages, this is realized as an array, vector, list, or sequence.
