Gatling vs Swagger UI: What are the differences?

Protocol Support: In Gatling, it primarily focuses on protocol-level testing, providing support for HTTP, JMS, and WebSocket protocols. On the other hand, Swagger UI is a tool for API documentation and exploration, allowing users to interact with HTTP APIs using a web interface.
Performance Testing vs API Documentation: Gatling is designed for performance testing and load testing scenarios, where it helps in simulating virtual users to test the application's performance under various conditions. In contrast, Swagger UI is used for API documentation, enabling developers to understand, visualize, and interact with APIs without the need for additional tools.
Scripting Language: Gatling utilizes Scala as its scripting language, allowing users to write performance test scripts in a concise and expressive manner. Swagger UI, on the other hand, generates documentation from OpenAPI Specification (formerly known as Swagger Specification), which is written in JSON or YAML format.
Graphical User Interface: Gatling is a command-line based tool, providing a scripting environment for users to create and execute performance test scripts. In comparison, Swagger UI offers a graphical web interface where users can explore API endpoints, test API requests, and view API documentation in an interactive format.

In Summary, Gatling focuses on performance testing with support for various protocols and a scripting language, while Swagger UI is primarily used for API documentation and exploration with a graphical user interface for interacting with HTTP APIs.

Needs advice

From a StackShare Community member: "I just started working for a start-up and we are in desperate need of better documentation for our API. Currently our API docs is in a README.md file. We are evaluating Postman and Swagger UI. Since there are many options and I was wondering what other StackSharers would recommend?"

Gatling

Locust

Flood IO

I have to run a multi-user load test and have test scripts developed in Gatling and Locust.

I am planning to run the tests with Flood IO, as it allows us to create a custom grid. They support Gatling. Did anyone try Locust tests? I would prefer not to use multiple infra providers for running these tests!

I want to do performance testing with HTTP protocol but the test script should be java script. For now, I kept "Artillery" and "K6" tools in my queue. Did you guys have any idea about this? Is there any tools which support Test script language: JavaScript Protocol: Http/web service Must Feature: Record OS: Mac os/windows

Detailed Comparison

Gatling	Swagger UI
Gatling is a highly capable load testing tool. It is designed for ease of use, maintainability and high performance. Out of the box, Gatling comes with excellent support of the HTTP protocol that makes it a tool of choice for load testing any HTTP server. As the core engine is actually protocol agnostic, it is perfectly possible to implement support for other protocols. For example, Gatling currently also ships JMS support.	Swagger UI is a dependency-free collection of HTML, Javascript, and CSS assets that dynamically generate beautiful documentation and sandbox from a Swagger-compliant API
Simulating heavy traffic; Load testing as code for CI/CD integration & automation; API Load testing; Automated deployment of load injectors; Response times reports	The UI works in any development environment, be it locally or in the web;Allow end developers to effortlessly interact and try out every single operation your API exposes for easy consumption;Quickly find and work with resources and endpoints with neatly categorized documentation;Cater to every possible scenario with Swagger UI working in all major browsers
