zeromicro/go-zero

go-zero is a web and RPC framework for building cloud-native microservices in Go.

The framework addresses the challenge of building stable, high-concurrency services by embedding resilience patterns directly into its core. It provides built-in timeout control, concurrency limits, rate limiting, adaptive circuit breakers, and adaptive load shedding without requiring explicit configuration. The tool includes goctl, a code generation command-line utility that reads API specifications and generates service code, client libraries, and SDKs across multiple languages including Go, iOS, Android, Kotlin, Dart, TypeScript, and JavaScript. Request parameter validation is performed automatically based on the API specification.

Teams building microservices that must handle high traffic and require production-grade reliability should consider go-zero. It suits projects where multiple services need consistent patterns for resilience and where cross-platform client generation reduces development effort. The framework's approach of encoding best practices into generated code means teams get stability features without manually implementing them. The simple API syntax and single-command code generation workflow appeal to teams prioritizing developer productivity.

The project shows sustained development activity with regular commits addressing bug fixes and feature enhancements. Maintenance responses to issues and pull requests occur consistently. The codebase receives ongoing refinement to the core resilience mechanisms and code generation capabilities. Documentation is actively maintained across multiple languages to support a global user base.
