About:
Vacuum is a high-performance linter specifically designed for OpenAPI 2.x and 3.x specifications, as well as Swagger files. It is written in Go and engineered for exceptional speed, capable of processing massive API definitions in milliseconds. The tool provides comprehensive validation, rule sets, and custom policy enforcement to ensure API quality and consistency.

Key Features:

Extreme performance, processing specifications in milliseconds
Supports OpenAPI 2.x (Swagger) and 3.x specifications
Extensible rule engine for custom linting policies
Detailed reporting with code snippets and error locations
Built-in spectral ruleset compatibility

Use Cases:

CI/CD pipeline integration for automated API contract validation
Pre-commit hooks to enforce API standards before code review
Migrating legacy Swagger files to modern OpenAPI specifications
Auditing large API portfolios for consistency and best practices

Alternatives:

Spectral – Spectral is the industry standard but runs on Node.js/JavaScript, making it slower than Go-based Vacuum for large files.
Redocly CLI – Redocly is a comprehensive toolchain focused on documentation generation as well as linting, whereas Vacuum is specialized for speed and validation.
