Ajv is a JSON Schema validator, and Spectral is a JSON/YAML linter. Instead of just validating against JSON Schema, it can be used to write rules for any sort of JSON/YAML object, which could be JSON Schema, or OpenAPI, or anything similar. Spectral does expose a
schema function that you can use in your rules to validate all or part of the target object with JSON Schema (we even use Ajv used under the hood for this), but that's just one of many functions.
No problem! A hosted version of Spectral comes free with the Stoplight platform. Sign up for a free account here.
Speccy was a great inspiration for Spectral, but was designed to work only with OpenAPI v3. Spectral can apply rules to any JSON/YAML object (including OpenAPI v2 and v3) through the use of JSONPath
given parameters. Some rule types have been enhanced to be a little more flexible along with being able to create your own rules based on the built-in functions, and we've added the ability to define custom functions too.
