Spectral is a flexible JSON/YAML linter for creating automated API style guides, with built-in rulesets for OpenAPI v2/v3.x, AsyncAPI v2.x, and Arazzo v1.0. It runs as a CLI, JavaScript library, or Docker image, and supports custom rules and functions for linting any JSON or YAML documents.
Use cases
- lint openapi specifications for style guide violations
- enforce api naming conventions across a team
- validate asyncapi documents in ci
- create custom rulesets for /yaml files
- automate api governance checks in a pipeline
- check swagger v2 documents for consistency
When to choose
- you need automated API style guide enforcement
- you want ready-made OpenAPI/AsyncAPI linting rules
- you need a generic JSON/YAML linter with custom rules
When to avoid
- you need runtime API validation rather than document linting
- you lint formats other than JSON/YAML
