## What it is
A JavaScript library and CLI tool that converts REST API description documents between formats such as Swagger/OpenAPI 2.0, OpenAPI 3.0, RAML, API Blueprint, WADL, Google Discovery, and I/O Docs. It can be used from the command line, in Node.js, or in the browser, with an accompanying web UI.

## Use cases
- convert swagger 1.0 spec to openapi 2.0
- migrate raml api definition to openapi
- convert api blueprint to swagger json
- upgrade openapi 2.0 spec to openapi 3.0
- convert wadl to openapi format
- validate converted api spec

## When to choose
- You need to migrate legacy API definitions (Swagger 1.x, RAML, WADL, API Blueprint) into OpenAPI 2.0 or 3.0
- You want a CLI or Node.js library for batch API spec conversion
- You need to unlock tooling that only supports OpenAPI formats

## When to avoid
- You need conversion between arbitrary format pairs - only conversion to OpenAPI 2.0 and from OpenAPI 2.0 to 3.0 is fully supported
- You need OpenAPI 3.1 support
- You need an actively maintained project - it is seeking a new maintainer

## Facets
- artifact type: library
