The complete JSON Schema specification as interactive help-text

JSONBuddy displays the text of the full JSON Schema specification for every keyword if you hover the mouse over it. This helps a lot if you are not sure about the definition or purpose of any JSON Schema keyword and increases productivity. The JSON Schema specification is well written and gives a good idea when and how a keyword shall be used. So it is a big help if you have it available directly in your editor.

You can also validate your JSON Schema document in JSONBuddy with a single click. Just use the "Validate against JSON Schema" command (usually F11) to validate your schema in the JSON Schema editor.

JSON Schema editor with $ref as links

Being able to navigate quickly and convenient in your JSON Schema can make a big difference while you are working on your schema definitions. JSONBuddy resolves the target locations of all $ref keywords in the current schema in the background and displays them as active links. The resolved JSON pointer and the path to the schema are shown as part of an info window if you move the mouse over the reference in the JSON Schema editor.

The sample data is automatically updated in the background if the schema is modified.
