I n the ever-evolving landscape of software development, selecting the right communication protocol for your APIs is crucial. Two of the most popular choices today are REST (Representational State Transfer) and gRPC (gRPC Remote Procedure Calls) . Both have their unique strengths and ideal use cases, but how do you decide which one is best suited for your project?
