Swagger is a reliable tool for writing API documentation, but its reliance on annotations and lack of permission control can hinder work efficiency. As a developer, creating API documentation is routine. For years, Swagger has been my default tool for this, but despite its powerful features, I've often found its dependence on annotations and lack of permission controls to be productivity-stifling. Fortunately, in 2024, I discovered EchoAPI, a tool that perfectly addresses these shortcomings of Swagger.
Swagger, also known as the OpenAPI Specification, is an open-source framework that simplifies the process of designing, documenting, and testing RESTful APIs. It provides a standardized and machine-readable way to describe the structure and functionality of an API, including details about endpoints, request and response formats, parameters, authentication methods, and more.
This documentation is written in JSON or YAML format and serves as a contract between API producers and consumers, ensuring that both parties have a clear understanding of how the API should behave. Swagger promotes consistency and collaboration in API development by offering a single source of truth that can be easily shared with developers, testers, and other stakeholders.
Swagger’s rich set of features simplifies API development and testing, making it an essential tool in the modern software development toolkit. Here are the top 5 features that make Swagger indispensable in the world of API development:
Swagger is a reliable tool for API documentation, but despite its rich features, the user experience is not perfect. Its reliance on annotations and lack of permission control can hinder productivity. Here are the common frustrations I've encountered while using Swagger:
Creating and maintaining Swagger documentation may have a steep learning curve, especially for those new to the OpenAPI Specification.
For very simple APIs, using Swagger might introduce unnecessary complexity due to its comprehensive approach.
Setting up Swagger documentation for an existing API can be time-consuming, particularly if the API lacks structured documentation.
Keeping Swagger documentation up-to-date can be challenging, and outdated documentation can lead to confusion and errors.
Swagger is primarily designed for RESTful APIs, and adapting it to non-RESTful APIs may require workarounds.
Incorporating Swagger into a project demands writing numerous annotations, which significantly increases my workload and annoyance. To illustrate this, consider the following example:
[@Api](/Api)(tags = "User-dependent interface")
[@RestController](/RestController)
[@RequestMapping](/RequestMapping)("user")
public class UserController {
[@ApiOperation](/ApiOperation)("Gets the user object by id")
[@GetMapping](/GetMapping)("/getById")
public Result<User> debug(Long id) {
User user = new User();
return Result.OK(user);
}
[@ApiOperation](/ApiOperation)("New user return")
[@PostMapping](/PostMapping)("/save")
public Result<User> save([@RequestBody](/RequestBody) User user) {
return Result.OK(user);
}
[@ApiOperation](/ApiOperation)("Modify the user and return")
[@PostMapping](/PostMapping)("/update")
public Result<User> update([@RequestBody](/RequestBody) User user) {
return Result.OK(user);
}
[@ApiOperation](/ApiOperation)("Delete a user by id")
[@DeleteMapping](/DeleteMapping)("/deleteById")
public Result<?> deleteById([@RequestParam](/RequestParam) [@ApiParam](/ApiParam)("id") Long id) {
return Result.OK();
}
}

Having to manually add annotations for every endpoint clutters the code and makes it harder to maintain.
Swagger lacks built-in permission configuration, meaning you can't restrict access to certain API documentation. This is particularly problematic when you need to document sensitive or proprietary APIs without exposing them to everyone.

After wrestling with Swagger’s UI for far too long, I started exploring alternatives. That’s when I discovered EchoAPI, a tool that completely transformed my API documentation workflow.
EchoAPI is an ultra-lightweight collaboration tool for API development, offering features like API design, debugging, automated testing, and load testing. Plus, it comes with plugins for IntelliJ IDEA(EchoAPI for IntelliJ IDEA), extension for VS Code(EchoAPI for VS Code), extension for Cursor(EchoAPI for Cursor), and a Chrome request capture extension(EchoAPI Interceptor), all without the need to log in.

| Features | Description |
| --- | --- |
| 1.API Debugging | In the process of debugging APIs, a lot of repetitive work takes up a significant amount of time, such as parameters (authentication tokens for login) that may be used by every interface. There is no need to set such parameters for each interface; the best approach is to place them in global parameters. EchoAPI's global parameters, global scripts, cookie management, and environment switching features can greatly reduce the amount of repetitive work and significantly improve the efficiency of API debugging! |
|2.Rapid Generation of Interface Documentation|EchoAPI can not only quickly generate interface documentation but also supports exporting offline HTML, Markdown, and Word documents. This makes it convenient for you to deploy interface documentation to your local or even intranet servers. |
| 3.Real-time Collaboration for Multiple Users | Traditional development scenarios are often siloed, leading to low collaboration efficiency. However, with EchoAPI, front-end and back-end developers can collaborate more effectively through a single interface document, enabling parallel development. Back-end developers can host the API on an API gateway, use EchoAPI's mock function to simulate data, and provide API information to front-end developers through the API documentation feature, achieving separation of front-end and back-end development. EchoAPI offers more localized collaboration features, allowing teams to work together in real-time, with new interfaces created by team members being synchronized across all team members' projects. For example, interfaces can be locked, preventing anyone other than the locker and administrators from editing or modifying them.
| 4.Automatic Code Generation | After filling in the interface request parameters, you can generate program code:EchoAPI provides HTTP request code for more than 10 different languages and various SDKs, allowing the code to be quickly integrated into your codebase.
| 5.Visualized UI| Easy-to-navigate interface for orchestrating tests. |
|6.Scratch Pad Support|Conveniently jot down temporary code snippets and ideas.|
| 7.Postman Script Compatibility|Users can transition easily, as EchoAPI fully supports Postman’s scripting syntax.|
|8. Powerful Integrations|Plugins available for IntelliJ IDEA, VS Code, and Chrome—all without requiring a login.|
This is the most direct method, suitable for one-time migration, especially when your API documentation is relatively stable. Here are the specific steps:

If the interface does not display a URL link, you can press 'F12' or 'Ctrl+Shift+I' to open the browser console, then navigate to 'Network -> Fetch/XHR' and refresh the entire page. A .json file will appear, which you can open in a new window and download.

After uploading the file, EchoAPI will automatically parse and import the API documentation, and you can further edit and manage it in the preview interface.

If your Swagger API documentation is frequently updated, manual export and import can be cumbersome. At this time, you can utilize EchoAPI's online link scheduled import feature, which can synchronize the online Swagger documentation according to a set schedule. Here are the specific steps:
Obtain an Online Link
Ensure that your Swagger documentation can be accessed via a public URL. For example:
** Import by Online Link**
In EchoAPI, enter the project that requires url import, and successively select 'Advanced -> Import Data -> Swagger URL.

If you are a developer using IntelliJ IDEA, you can download the EchoAPI for IntelliJ IDEA plugin. This plugin can generate interfaces directly from your code and instantly share them as API documentation, all without needing to install a separate client. It's incredibly lightweight and hassle-free.

In conclusion, migrating from Swagger to EchoAPI offers a streamlined approach to API documentation and development. EchoAPI addresses the common pain points associated with Swagger, such as annotation dependency and lack of permission controls, while providing a user-friendly interface and powerful features like real-time collaboration and automated code generation. By following the outlined methods for migration, developers can enhance their API development workflow and maintain up-to-date documentation with minimal effort. EchoAPI is a valuable asset for any development team looking to improve efficiency and collaboration in the API development process.
