Edit and format JSON with ease

JSON schema linter

The main purpose of the JSON schema linter is to catch issues and critical errors in schema specifications early and automatically. This helps to increase the quality of the schema pool and to avoid breaking the work-flow. The linter reports issues, which are not covered by the standard schema validation. As an example, a broken $ref link, or missing definitions are detected and can be fixed immediately.

This JSON schema linter page is a simple showcase of the live analyzer available in JSONBuddy. The linter, available using the web form, offers the complete functionality but is currently limited to schemas with less than 5 KB of text. The report is generated on the server using the command-line tool which is part of the JSONBuddy software package. You can find a list of currently detected issues by the schema linter here

During the testing period, the WebAPI is accessible without any authentication. Using the API, any input schema is limited to 10 KB of size.
