go-kratos/kratos

This system is a comprehensive Go-based microservices framework (Kratos v3) that provides a complete lifecycle for building distributed applications. It offers a modular architecture for transport (HTTP, gRPC, MCP), service discovery, and configuration management across various backends like Consul, Nacos, and Kubernetes. The framework also includes extensive middleware support for observability, security, and traffic control, alongside robust code generation tools for Protobuf and CLI utilities.

About this page

  • The description of this project is derived from its own commit history, not from its README.
  • The score is its highest published measurement, taken on 29 July 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit 668db92c2c — the exact code this score is about.
  • Scored under rubric rubric-2026.08.18. Score the same commit under that rubric and you get the same number.
