The prosperity of the Go language community is as lively as a summer night food stall, with a dazzling array of frameworks to choose from. Today, let's act as "connoisseurs" and talk about the four "martial arts masters": Kratos, Go-Zero, GoFrame, and Sponge, to see which one you should bet your next project on.

When starting a new project, are you scratching your head again over which framework to choose? On one hand, there's "analysis paralysis," and on the other, the "holy wars" among the senior developers in your team. It's almost more tiring than writing code.

Today, let's bring four Go frameworks with distinct styles—Kratos, Go-Zero, GoFrame, and Sponge—onto the stage. We'll discuss their tempers, characteristics, and unique skills to help you find the one that's the perfect match.

The Arena Showdown: Which One is Your Cup of Tea?

Applicable Scenarios Medium to large-scale microservice projects Medium to large-scale microservice projects Small, medium, to large-scale projects Medium to large-scale microservice projects

From the comparison above, everyone should have a rough picture of each "contestant":

  • Kratos: A product of Bilibili, battle-tested, focusing on microservices. It emphasizes "modularity" and "extensibility," exuding the rigor of an "architect."

  • Go-Zero: A lightning-fast efficiency tool. It pursues ultimate performance and simplicity, coming with its own code generation tools, like an efficiency-first assassin who strikes fatally without any delay.

  • GoFrame: An all-encompassing Swiss Army knife. Nicknamed "GF," its goal is to be your development "family bucket." It can do everything from web development to backend services, focusing on being "out of the box" and "development efficiency."

  • Sponge: The low-code black magician embracing the future. This is the newcomer "raising the bar." It brings a philosophy of "Definition is Code," not only wanting you to write less code but even having a built-in AI to help you write business logic, which is a bit of an unfair advantage.

Next, let's have a head-to-head confrontation from the angles everyone cares about most.

1. Learning Curve & Ease of Use: Who is More Approachable?

Winners: GoFrame, Sponge

  • GoFrame: If you're a Go novice or your project is all about being "short, simple, and fast," then GoFrame is definitely a blessing. Its design philosophy is "simple and easy to use," with clear documentation and an active community, lowering the barrier to entry.

  • Sponge: This one takes another "minimalist" route. Its low-code concept allows you to focus only on the most important business logic (defining data models and APIs), and it handles the rest. It can even use its built-in AI to help you fill in the business logic, making it extremely friendly for beginners with a very low learning curve. You can generate complete, compilable, and deployable service code (http or gRPC) just by connecting to a database.

  • Kratos and Go-Zero, due to their distinct microservice architecture concepts, require you to first understand their design patterns (like Kratos's layering, Go-Zero's .api specification), so their learning curve is slightly higher, at a "medium" level.

2. Microservice Support: Who is More Practical?

Evenly Matched: Kratos, Sponge

Potential Contender: Go-Zero

All four support gRPC and are capable of microservice development. But the details vary greatly.

  • Kratos and Sponge support HTTP+RPC hybrid services. This means you can use one set of code to expose both HTTP/JSON interfaces to the frontend and gRPC interfaces for internal service calls. This is very practical in modern microservice architectures and can effectively reduce maintenance costs.

  • Go-Zero and GoFrame are more "specialized" in this regard. The services they generate are either pure HTTP or pure gRPC, and they don't support mixing them in the same service instance.

So, if your microservice system requires flexible interface formats, Kratos and Sponge would be a better choice.

3. The Love-Hate Relationship with ORM: Built-in or Choose Your Own?

The Built-in Camp: Go-Zero, GoFrame, Sponge

The Freedom Camp: Kratos

This is a classic "sweet tofu pudding" versus "salty tofu pudding" debate.

  • GoFrame and Go-Zero both have powerful built-in ORMs that work out of the box, saving you the trouble of choosing and integrating one. For most projects, this is very convenient.

  • Sponge goes a step further. It not only has built-in GORM and Mongo drivers but also has designed a template mechanism. Theoretically, you can customize templates to have it generate any type of ORM code for you, which is very flexible.

  • Kratos insists on "architectural purity." It does not include a built-in ORM, giving the choice entirely to you. You are free to choose GORM, SQLx, or any library you like. This is an advantage for teams with specific technology stack requirements or those who like to have control over everything.

4. Code Generation: Who is the Real "Lazy Person's Gospel"?

The King: Sponge

The Strong Contenders: Go-Zero, GoFrame

In this era of "if it can be automated, never write it by hand," code generation capability is an important measure of a framework's productivity.

  • Go-Zero's goctl toolchain is very powerful. With an .api file, you can generate an entire service skeleton with one click, greatly improving development efficiency.
  • GoFrame's gf development tool generates corresponding service code through .yaml configuration, improving development efficiency.
  • Sponge takes this to the extreme. Its philosophy is "Definition is Code." You can start from SQL, Protobuf, or even JSON to generate service code, including Web and gRPC, with complete CRUD functionality. The most "outrageous" part is that it has built-in AI! You can have DeepSeek/ChatGPT/Gemini help you fill in the specific business logic code while maintaining a consistent code style. It truly achieves semi-automation from definition to business logic, making it the "pinnacle of development efficiency."

Kratos also supports code generation, but compared to the other three, it is slightly more conservative in terms of "automation" and "intelligence."

Who Should Your Project Choose?

Based on the comparison above, here are some selection recommendations:

If you are: A large enterprise or a die-hard fan of Bilibili, pursuing architectural standardization, stability, and ultimate extensibility.

👉 Choose Kratos.

Kratos is like an experienced architect who lays a solid foundation and provides a clear blueprint for you. Although it requires some initial investment to understand its design philosophy, this investment is worthwhile for large-scale microservice projects that need long-term evolution and collaboration among many people. It ensures your project won't "go off track" in the future.

If you are: A team pursuing ultimate performance and development efficiency, with a business centered around APIs.

👉 Choose Go-Zero.

Go-Zero is like a sharp dagger: fast, precise, and ruthless. All its designs are for performance and efficiency. With the powerful goctl tool, you can build and iterate API services like on a production line, which is very suitable for internet projects that need to quickly capture the market.

If you are: A small to medium-sized team pursuing efficient development and needing to quickly develop and validate projects.

👉 Choose GoFrame.

GoFrame is your "universal toolbox." It has everything, and everything works well. You don't need to spend too much time on technology selection and component integration to quickly implement business functions. Its development experience is very smooth, making it an excellent choice for rapid prototyping and small to medium-sized projects.

If you are: A team pursuing the ultimate in development efficiency, needing to maintain the flexibility and extensibility of the project architecture.

👉 Choose Sponge.

Sponge is a "magician" from the future. It uses the power of low-code and AI to push development efficiency to new heights. It can quickly build small and medium-sized web services, and like Kratos, it can also build complex large-scale microservice projects. It also supports hybrid services and is feature-complete. It is especially suitable for teams that want "all of the above" and is the ultimate weapon for improving the overall productivity of a team.

In Conclusion

Of course, there is no absolute "best" framework, only the "most suitable." Hopefully, this article helps you cut through the fog and see the true faces of these "masters."

The best way is to get your hands dirty, spend some time running their Hello World, and get a "feel" for them. After all, the code doesn't lie.
