gRPC is a high-performance, open-source framework for remote procedure calls, developed by Google, that enables fast, efficient communication between distributed systems.
Unlike REST or GraphQL, gRPC uses Protocol Buffers (Protobuf) to serialize data, making it ideal for low-latency, high-throughput applications. It supports bi-directional streaming and is widely used in microservices, real-time systems, and cloud-native infrastructure.
gRPC is especially valuable when building internal APIs that require speed, versioning, and strong type safety across services written in different languages.
