❓ FAQs
How is this different to Ajv
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.
I want to lint my OpenAPI documents but don't want to implement Spectral right now.
No problem! A hosted version of Spectral comes free with the Stoplight platform. Sign up for a free account here.
What is the difference between Spectral and Speccy
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/v3, Arazzo, and AsyncAPI). Speccy has mostly been abandoned now, and is JavaScript not TypeScript.
