A modern, high-performance remote procedure call (RPC) framework that enables transparent client-server communication across multiple languages.
gRPC is a modern, open-source remote procedure call (RPC) framework that enables efficient and transparent communication between client and server applications. It simplifies building connected systems by providing high-performance, language-agnostic libraries for seamless inter-service communication, often using protocol buffers for data serialization.
Developers and engineers building microservices, distributed systems, or any application requiring efficient, cross-language client-server communication, such as backend services, cloud-native applications, and IoT platforms.
Developers choose gRPC for its high performance, multi-language support, and standardized approach to RPC, which reduces boilerplate and ensures reliable communication across diverse tech stacks. Its strong ecosystem and active community make it a robust choice for scalable systems.
C++ based gRPC (C++, Python, Ruby, Objective-C, PHP, C#)
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Supports over 10 languages including C++, Java, Python, and Go, with standardized package manager integration like pip and npm, making cross-platform development seamless as listed in the installation instructions.
Built on an optimized C++ core library with daily performance tracking and bleeding-edge builds uploaded to packages.grpc.io, ensuring efficient communication for distributed systems.
Integrates with language-specific package managers such as NuGet for .NET and pip for Python, simplifying adoption and maintenance as detailed in the README's dependency section.
Offers per-language quickstart guides, tutorials, and troubleshooting resources on grpc.io, accelerating development and reducing onboarding time.
Requires defining services with protocol buffers and compiling .proto files, adding steps and learning curve compared to simpler APIs like REST, especially for new users.
Native gRPC isn't supported in browsers; gRPC-Web is required as a separate library, which may not support all features and necessitates additional server-side proxies, as indicated in the grpc-web repository link.
Libraries are in various states of development across languages, leading to potential disparities in feature support, stability, and performance, as noted in the README's language status table.
For trivial APIs or small projects, the binary serialization and RPC framework can introduce unnecessary complexity and overhead compared to lighter alternatives like HTTP/JSON.
