Why should I use gRPC ?

gRPC is a modern, high-performance, and open-source framework for building efficient and robust remote procedure call (RPC) applications. Developed by Google, gRPC offers a wide range of benefits that make it an excellent choice for building microservices architectures, distributed systems, and APIs. In this article, we'll explore the key reasons why you should consider using gRPC in your software projects.

Protocol Buffers (ProtoBuf): One of the primary advantages of gRPC is its use of Protocol Buffers (ProtoBuf) as the interface definition language (IDL) for defining service contracts. ProtoBuf is a language-agnostic binary serialization format that allows you to define data structures and services in a concise, language-neutral manner. This means that you can define your API once and generate client and server code in multiple programming languages, making it easy to build interoperable services.

Efficient and Performant: gRPC is designed for efficiency and high performance. It uses HTTP/2 as the transport protocol, which provides features like multiplexing, header compression, and stream prioritization. These features make gRPC ideal for scenarios where low latency and high throughput are critical, such as real-time applications and microservices communication.

Strongly Typed APIs: With gRPC, service contracts and message types are strongly typed, which helps catch errors at compile-time rather than runtime. This means that you get better type checking, code completion, and tooling support when working with gRPC APIs. Additionally, the generated client and server code is type-safe, reducing the chances of runtime errors and improving maintainability.

Bidirectional Streaming: gRPC supports bidirectional streaming, allowing both the client and server to send multiple messages over a single connection concurrently. This feature is particularly useful for building real-time applications, chat systems, or any use case where continuous data exchange is required.

Code Generation: gRPC uses code generation to create client and server code from your service definitions. This means that you define your API using ProtoBuf, and gRPC generates the necessary code for you in your chosen programming language. This automation reduces the boilerplate code you need to write and ensures consistency between clients and servers.

Authentication and Security: gRPC provides robust authentication and security features out of the box. It supports various authentication methods, including SSL/TLS for secure communication. Additionally, gRPC allows you to implement custom authentication mechanisms if needed, making it suitable for a wide range of security requirements.

Built-in Features: gRPC includes built-in support for features such as load balancing, connection pooling, and health checking. These features simplify the development of highly available and scalable applications, as they can be configured and managed directly through gRPC.

Cross-Platform Compatibility: gRPC is a polyglot framework, which means it supports multiple programming languages. Whether you're building services in Go, Java, Python, JavaScript, or any other supported language, gRPC ensures compatibility between client and server components, enabling you to create heterogeneous systems with ease.

Open Source and Active Community: gRPC is an open-source project with an active and growing community. This means you can benefit from ongoing improvements, updates, and contributions from developers worldwide. The active community also ensures that gRPC stays up-to-date with the latest technologies and best practices.


In conclusion, gRPC offers numerous advantages that make it a compelling choice for building modern, efficient, and scalable applications. Its use of Protocol Buffers, strong typing, performance optimizations, and built-in features make it well-suited for microservices architectures, distributed systems, and APIs. As the software development landscape continues to evolve, gRPC stands as a robust and versatile tool for building high-performance networked applications. Whether you're working on cloud-native applications, IoT devices, or any distributed system, gRPC is a technology worth considering to streamline your development process and enhance your application's performance.
