The API testing market consists of API testing tools and services, which are offered to facilitate the continuous delivery of the software, as the software development and test teams strive to work parallel on the software testing capabilities. API testing is adopted as an efficient Quality Assurance (QA) strategy as businesses move toward DevOps and Agile practices for software development. This allows the QA teams to focus on quality from the beginning of the software development life cycle. Thus, an early feedback on the business risks associated with a software release candidate can be identified as rapidly as possible.

The vendors have been placed into 4 categories based on their performance in each criterion: visionary leaders, innovators, emerging, and dynamic. We have evaluated the top 25 vendors, including IBM, Micro Focus (Formerly HP Software), SmartBear Software, Parasoft, Tricentis, SendGrid, Inflectra Corporation, Cigniti, Oracle, CA Technologies, Infosys, Axway, QualityLogic, Trantor, Bleum, LogiGear Corporation, QASource, QSG Technologies, Sybrant Technologies, Vector Software, Load Impact, Nevatech, Runscope, Astegic, and Cygnet Infotech.

The visionary leaders receive high scores for most of the evaluation criteria. They have an established product portfolio and a very strong market presence. They provide mature and reputable API testing solutions and services. They also have strong business strategies. IBM, Micro Focus (Formerly HP Software), SmartBear Software, Parasoft, and Tricentis fall into this category.

The dynamic differentiators are established vendors with very strong business strategies. However, they have a low product portfolio. They focus on a specific type of technology related to the product. Oracle, CA Technologies, Axway, QualityLogic, and Infosys fall into this category.

The innovators demonstrate substantial product innovations as compared to their competitors. They have a very focused product portfolio. However, they do not have very strong growth strategies for their overall business. Dynatrace, QASource, and Cigniti fall into this category.

The emerging companies have niche product offerings and are starting to gain their position in the market. They do not have much strong business strategies as compared to other established vendors. They might be new entrants in the market and require some more time before getting significant traction in the market. Trantor, Bleum, LogiGear Corporation, QSG Technologies, Sybrant Technologies, Vector Software, Load Impact, Nevatech, Runscope, Astegic, and Cygnet Infotech fall into this category.
