7days-golang vs go-zero
Which should you use? A side-by-side look at what each one does, who it suits, what it costs, how hard it is to set up, and where each falls short.
Open source · MIT
A tutorial series that builds a web framework, cache, ORM, and RPC library from scratch in Go.
Open source · MIT
A Go framework for building web and RPC microservices, with a code generator called goctl.
The short answer
Choose 7days-golang if you need…
- Developers who want to understand how web frameworks, caches, ORMs, or RPC libraries work internally
- Students learning Go who prefer reading and running small, step-by-step code
- Engineers preparing for interviews that cover Go internals
- Readers who already know basic Go syntax and want to practice designing small libraries
Choose go-zero if you need…
- Go developers building REST APIs or microservices
- Teams that want built-in resilience features like rate limiting and circuit breakers without writing them by hand
- Developers who want code generated from an API description file

What each one is
7days-golang
This is a set of Go code examples organized as a 7-day build-along course. Each day adds one feature to a small project, such as a web framework similar to gin, a distributed cache similar to groupcache, an ORM similar to gorm and xorm, and an RPC framework based on net/rpc. Each day links to a written explanation and a code folder so you can see how the pieces fit together.
go-zero
go-zero is a framework for writing web APIs and RPC services in Go. It includes built-in engineering features such as timeouts, rate limiting, circuit breaking and load shedding, meant to keep busy services stable. Its goctl tool generates Go server code and client code in other languages from a simple .api description file.

go-zero
- Go developers building REST APIs or microservices
- Teams that want built-in resilience features like rate limiting and circuit breakers without writing them by hand
- Developers who want code generated from an API description file
Strengths
7days-golang
- Breaks each system into seven small, sequential steps with a linked explanation and code folder for each
- Covers several distinct areas of backend work (web routing, caching, databases, RPC) in one place
- Available in both English and Chinese versions of the README
go-zero
- Includes resilience features such as rate limiting, circuit breaking and load shedding
- Code generation reduces repetitive setup code
- The README says it is used by sites with tens of millions of users
Not ideal for
7days-golang
- People who need a production library to use in an app, since these are teaching projects built to show concepts rather than to be used in production
- Complete beginners to programming, because the README assumes familiarity with Go and linking to a separate basics tutorial is recommended
- People looking for a maintained, feature-complete framework with releases, since the README lists no release
go-zero
- Developers who prefer to write everything by hand or use only the standard library, since go-zero generates a lot of boilerplate and adds its own conventions
- Non-Go teams, because the framework is written for Go
Trade-offs
7days-golang
- The README does not state a specific Go version or describe how to run the code, so setup details are unclear from this text
- The projects are educational re-implementations and the README does not claim they are production-ready
- The README is truncated here, so some details about individual days could not be verified
go-zero
- Heavy reliance on generated code and its own conventions can make it harder to adopt piecemeal
- The README is truncated, so detailed configuration options are not visible here
- Documentation links point to a separate zero-doc repository and a homepage I could not verify
