What it is

Micro is a minimalistic microservice framework that focuses on simplicity and performance. It uses an asynchronous approach to handle requests, making it suitable for high-performance applications.

Micro stands out as a lightweight, high-performance microservice framework that prioritizes simplicity and ease of integration over comprehensive feature sets.

When it fits — and when it doesn’t

A good fit for

  • Developers looking for a lightweight framework to build high-performance microservices

  • Teams needing an easy-to-integrate solution for creating lightweight APIs

  • Projects requiring minimal overhead and maximum performance in their backend services

Look elsewhere if

  • Applications that require complex service orchestration or extensive built-in features beyond basic request handling

  • Developers who prefer a more comprehensive framework with out-of-the-box solutions for common tasks

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 JavaScript

    Primary focus on JavaScript limits its utility for polyglot microservices architectures.

  2. 02

    Poor documentation and community support

    Official docs are sparse, with limited examples and tutorials; community forums have low activity.

  3. 03

    Complex setup for non-trivial applications

    Configuring services, dependencies, and external integrations can be cumbersome without comprehensive guides.

  4. 04

    Performance degradation under heavy load

    Asynchronous handling may lead to performance bottlenecks when dealing with a large number of concurrent requests or complex operations.

What it does well

  • Minimalistic design for high performance

  • Asynchronous request handling

  • Lightweight and easy to integrate
