Swagger Codegen vs OpenAPI: What are the differences?

Developers describe Swagger Codegen as "Generate API clients or server stubs for REST API *". It is an open source project which allows generation of API client libraries (SDK generation), server stubs, and documentation automatically from an OpenAPI Specification. On the other hand, *OpenAPI** is detailed as "Allows the owner of a network-accessible service to give universal access". It is a publicly available application programming interface that provides developers with programmatic access to a proprietary software application or web service.

Swagger Codegen and OpenAPI can be primarily classified as "API" tools.

Swagger Codegen and OpenAPI are both open source tools. It seems that OpenAPI with 15.4K GitHub stars and 5.46K forks on GitHub has more adoption than Swagger Codegen with 10.2K GitHub stars and 4.76K GitHub forks.

According to the StackShare community, Swagger Codegen has a broader approval, being mentioned in 20 company stacks & 4 developers stacks; compared to OpenAPI, which is listed in 3 company stacks and 4 developer stacks.
