Company Overview
Swagger is the world's most well-known API specification standard and tool ecosystem. Created in 2011 by Tony Tam, the Swagger specification was later donated to the OpenAPI Initiative and renamed the OpenAPI Specification. It is now maintained and operated by SmartBear. The Swagger ecosystem includes Swagger Editor (API specification editor), Swagger UI (interactive API documentation generator), Swagger Codegen (client SDK generation), and the enterprise platform SwaggerHub.
