go-zero (listed in CNCF Landscape: https://landscape.cncf.io/?selected=go-zero) is a web and rpc framework with lots of builtin engineering practices. It’s born to ensure the stability of the busy services with resilience design and has been serving sites with tens of millions of users for years.
go-zero contains simple API description syntax and code generation tool called goctl. You can generate Go, iOS, Android, Kotlin, Dart, TypeScript, JavaScript from .api files with goctl.
Advantages of go-zero:
- Improves the stability of the services with tens of millions of daily active users
- Builtin chained timeout control, concurrency control, rate limit, adaptive circuit breaker, adaptive load shedding, even no configuration needed
- Builtin middlewares also can be integrated into your frameworks
- Simple API syntax, one command to generate a couple of different languages
- Auto validate the request parameters from clients
- Plenty of builtin microservice management and concurrent toolkits
Backgrounds of go-zero
In early 2018, we transitioned from a Java+MongoDB monolithic architecture to microservices, choosing:
- Golang - High performance, simple syntax, excellent deployment experience, and low resource consumption
- Self-designed microservice framework - Better problem isolation, easier feature extension, and faster issue resolution
Design considerations on go-zero
go-zero follows these core design principles:
- Simplicity - Keep it simple, first principle
- High availability - Stable under high concurrency
- Resilience - Failure-oriented programming with adaptive protection
- Developer friendly - Encapsulate complexity, one way to do one thing
- Easy to extend - Flexible architecture for growth
The implementation and features of go-zero
go-zero integrates engineering best practices:
- Code generation - Powerful tools to minimize boilerplate
- Simple API - Clean interfaces, fully compatible with net/http
- High performance - Optimized for speed and efficiency
- Resilience - Built-in circuit breaker, rate limiting, load shedding, timeout control
- Service mesh - Service discovery, load balancing, call tracing
- Developer tools - Auto parameter validation, cache management, metrics and monitoring
Architecture with go-zero
Installation
Run the following command under your project:
go get -u github.com/zeromicro/go-zero
AI-Native Development
The go-zero team provides workflow guidance and implementation patterns for AI coding assistants such as Claude Code, GitHub Copilot, and Cursor. For assistants with terminal access, the recommended workflow is to run goctl directly to generate framework-compliant code.
AI Tooling Projects
- ai-context - Workflow guidance: how to approach go-zero development tasks and when to use goctl.
- zero-skills - Implementation patterns, examples, and goctl command reference, loaded as needed.
- mcp-zero - Optional adapter that exposes goctl code generation through the Model Context Protocol (MCP).
Quick Setup
Install goctl and ensure it is available in your $PATH:
go install github.com/zeromicro/go-zero/tools/goctl@latest
goctl --version
Follow the ai-context setup guide and zero-skills integration guides to configure your assistant's workflow instructions and pattern library.
How It Works
- Consult ai-context for the workflow and zero-skills for relevant patterns.
- Define the
.api or .proto specification, then run goctl in the terminal to generate code.
- Implement business logic, resolve dependencies, build, and test the service.
Example: Create a REST API → write the .api specification → run goctl api go → implement the logic using zero-skills patterns → run go mod tidy, go build ./..., and go test ./....
Optional MCP Integration
For clients that use MCP tools, such as Claude Desktop, configure mcp-zero to invoke goctl through MCP. It uses the same code generation engine; assistants with terminal access can use the direct workflow above without an MCP server.
