## What it is
Kratos is a lightweight Go framework for building cloud-native microservices, offering APIs for transport (HTTP/gRPC), middleware, registry, configuration, logging, and Protobuf-based code generation. It includes a CLI tool for scaffolding projects and a pluggable component architecture.

## Use cases
- build microservices in go
- generate http and grpc servers from protobuf definitions
- scaffold a production-ready go backend project
- add middleware for logging tracing and auth to go services
- service discovery and registry for go microservices
- learn microservices architecture in go

## When to choose
- you are building cloud-native microservices in Go and want an opinionated, batteries-included framework
- you want API-first development with Protobuf generating both HTTP and gRPC code
- you need pluggable registry, config, and encoding components with a CLI scaffolding tool

## When to avoid
- you are building a small monolith or simple REST API where a lighter router suffices
- your team is not using Go or Protobuf-based workflows
- you prefer assembling your own stack from individual libraries rather than a framework
