What it is

zerorpc is a flexible Remote Procedure Call (RPC) library built on top of ZeroMQ for messaging and MessagePack for serialization, enabling efficient communication between processes or machines.

zerorpc stands out as a lightweight, high-performance RPC library built on ZeroMQ and MessagePack, ideal for developers looking to build efficient distributed systems without the overhead of heavier frameworks.

When it fits — and when it doesn’t

A good fit for

  • Developers building high-performance, distributed applications in Python

  • Teams requiring efficient inter-process communication and serialization

Look elsewhere if

  • Projects that require real-time streaming capabilities (zerorpc is not designed for this)

  • Applications needing a web-based UI or platform integration

Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

  1. 01

    Limited language support beyond Python

    Primary development is in Python, with limited official support for other languages like TypeScript or Java

  2. 02

    Small community and slower issue resolution

    GitHub repository has low activity compared to more popular RPC frameworks

What it does well

  • Built on ZeroMQ for high-performance messaging

  • Uses MessagePack for efficient data serialization

  • Flexible RPC implementation suitable for various use cases
