OpenAPI is mainly the official name for the specification. Moreover, the development of the specification is mainly fostered through the OpenAPI Initiative that mainly involves above 30 organizations of diverse areas of the tech world — that includes IBM, Microsoft, capitalOne, and Google. However, Smartbear Software is a company that leads the development of Swagger tools and it is even a member of Initiative done by OpenAPI thereby helping the lead for the evolution of specification.

Swagger is a name that is generally associated with most well-known as well as extensively used tools to implement the specification of OpenAPI. Also, Swagger toolset consists of a mix of the open-source which is a free and commercial tool that may be also used at various stages of the lifecycle of API.

These tools mainly consist of:

Swagger Editor: It allows you to edit the OpenAPI specifications in YAML that is inside the browser and also to preview documentations based on real-time.

Swagger UI: The Swagger UI is mainly the collection of the HTML, CSS assets and Javascript that dynamically generate some of the stunning documentation from the API which is OAS-compliant.

Swagger Codegen: It permits the generation of the libraries of API clients such as SDK generation, and the server stubs along with documentation that is automatically given with the spec of OpenAPI.

Swagger Parser: It is mainly the Standalone library for parse definition of OpenAPI from Java

Swagger Core: It is the Java-related libraries that can create, work and can consume with the definitions of OpenAPI

Swagger Inspector: It is the API testing tool which allows you to simply validate the APIs & generate the definition of OpenAPI from the current API

SwaggerHub: It is commercial and free of cost where the API design, as well as documentation, is created for the teams that are working with the OpenAPI.

As a Swagger tool that was developed by a team that is mainly involved in the creation of the original Specification of Swagger, the tools that are usually viewed as being synonymous with specific specs. However, Swagger tools usually are not only tools that are available to implement the specification of OpenAPI. There is an extensive variety of the API design, testing, documentation, management along with monitoring solutions which support the version 2.0 for the set specification, and they also working actively for adding the support of 3.0 versions.

Why have the Swagger tools also changed the name to OpenAPI?

The ecosystem of Swagger also has been comprised of Specification and core open the tooling source around it, quite famously Swagger UI, Swagger Codegen and Swagger Editor. The great reason why it is about Specification as it has become much extensively adopted because of the reason the tooling has lived alongside.

Here, SmartBear donated Specification, but famous and renowned open-source for Swagger tooling retained original branding because of the strong association of the developers, tech writers, designers and also testers that had with such tooling.

The specification mainly is not, and also has not been associated solely with tools of Swagger. The decision about donating the specification as well as the form of the OpenAPI Initiative is mainly to make sure that OpenAPI stays completely neutral. This is the reason that we are thrilled to check various people across API space that includes companies that even support various formats of definition such as API Blueprint as well as RAML.

Understanding about Swagger Communities and OpenAPI

Though there will be some overlap between people which contribute to OpenAPI, and also those which contribute to the tooling of Swagger, such two communities are mainly independent of one other. As it is mentioned, the initiative of OpenAPI is an open organization that is vendor-neutral that greets involvement from anyone who wants to assist evolving or even leveraging specification in the development of API. Organizations also are invited for joining a growing list of the members contributing to this kind of Specification, and also people are welcome for participating through sharing their feedback and ideas or attending various OAS meetups that are held at the locations around the world every month.

The tool of Swagger has a community of their own; it is focused on improving the current projects of Swagger, and introduces some great ideas and even feature. The community of Swagger is well fostered by the team at the SmartBear Software that invests in the development of tools of open source Swagger, but it is even driven by contributions for various swagger users that are located all around the world.

Looking ahead for the bright future of OpenAPI

We are now looking ahead to see the OpenAPI that becomes the name that everyone in API space usually recognizes, and we are also much thrilled to be a part of the growing community being the initiative members of OpenAPI. With this, you will be quite cleared about the questions and queries about OpenAPI and their relationship with the Swagger.

Let us quickly recap:

– The Specification got renamed to OpenAPI Specification in the year 2015. The OpenAPI 3.0 is the latest and updated version of the specification.

– The tool of Swagger is usually supported by SmartBear Software, that is among the much popular tools that implementing specification of OpenAPI, and it will continue to simply maintain the name of Swagger (Swagger UI, Hub, Swagger Editor, and others)

– Various pro tools are not related to Swagger, which supports OpenAPI 2.0 Specification, and list of the tools that support 3.0 which grows regularly.

– Swagger and OpenAPI both have some of the open-source communities.


When the software is developed software, the possibility is that you will be developing the Web APIs. On the other hand, while you may not be a company such as Twilio this is running to have the great public API program, and also there is yet some great chance that you are building the APIs for also some of the chosen partners or just for internal use. Like an instance for connecting the native application of mobile at the backend.
