RSocket

gRPC is a modern open source high performance RPC framework that can run in any environment. It can efficiently connect services in and across data centers with pluggable support for load balancing, tracing, health checking...

It is a high-performance, light weight, java based RPC framework. Dubbo offers three key functionalities, which include interface based remote call, fault tolerance & load balancing, and automatic service registration & discovery.

It is a very simple protocol, defining only a few data types and commands. It allows for notifications (data sent to the server that does not require a response) and for multiple calls to be sent to the server which may be answered out of order.

A modular JSON-RPC library that allows pluggable transport layers, JSON libraries, and effect/async monads. It is used to communicate with embedded devices where the device is acting in the server role.

It is an open-source microservice platform. It contains a high-performance RPC framework and a service management platform. Based on Tars, you can develop a reliable microservice system efficiently. It is designed for high reliability, high performance, and efficient service management. By significantly reducing system operation work, developers can focus on business logic and meet fast changes of user requirements.

It is a high-performance and strong-extensibility Golang RPC framework that helps developers build microservices. If performance and extensibility are the main concerns when you develop microservices, it can be a good choice.

It is a modern back-end framework with full-stack capacities written in Typescript. Its main feature is to facilitate communication in a safe way between server and client by using a remote procedure call system. It will give you the power to call a function defined in the server directly from the client - like if it's just a normal Javascript function.

It is a proto3-compatible RPC Framework that's designed from the ground up to be lightweight, extensible, and extremely performant. On average fRPC outperforms other RPC frameworks by 2-4x in an apples-to-apples comparison, and is easily able to handle more than 2 million RPCs/second on a single server.
