What is OpenAPITools/openapi-generator?
OpenAPI Generator is a tool that automatically creates API client libraries, server code, and documentation from an OpenAPI specification file. Developers use it to eliminate manual SDK generation work and keep client libraries synchronized with API changes, supporting both OpenAPI v2 and v3 specifications. It generates boilerplate code for multiple programming languages and frameworks, reducing the time needed to integrate with or build REST APIs.
