OpenAPI uses HTTP/1.1 protocol for transport. Later on, it was donated to Cloud Native Computing Foundation. While the original Swagger Specification was donated to the Linux Foundation and renamed the OpenAPI, Swagger remains one of the most widely used open source tool sets for developing OpenAPIs.
#MPI VS GRPC VS REST CODE#
Later on, tools to generate client and server code and generating of test-cases were added. Swagger started out as a specification for documenting RESTful APIs. OpenAPI evolved from the Swagger project. I didn’t include every single detail, however, this table could perhaps be a good starting point for you: Criteria As there are two viable alternatives, the question is which one is going to work better for you? As I was trying to answer the same question I did some research on the Internet and came up with a comparison table.
This description then serves as a source of truth from which you can generate the client and server code and API documentation. They allow you to describe your APIs using a formal language. In this article, we are going to look at OpenAPI and gRPC side-by-side.īoth OpenAPI and gRPC are communication technologies very much needed in the today’s world of microservices applications. Are you still coding your API client libraries by hand? Is your manually maintained API documentation drifting away from what was actually implemented? You may be interested in reviewing the two popular technologies that solve this problem.
