What are Postman and Katalon?
Postman is an all-in-one platform for working with APIs throughout their entire lifecycle. It provides tools to send API requests, view responses, write tests, create documentation, and monitor performance. Unlike basic HTTP clients, Postman offers a complete environment where teams can organize their work into collections, share them with teammates, and automate testing.
The platform includes an easy-to-use interface where you can build requests without writing code, though it also supports advanced scripting when needed. Postman works as a desktop app, web app, or through command-line tools for automation. It integrates with popular development tools and supports team collaboration through workspaces, making it ideal for both individual developers and large organizations building complex API systems.
Katalon is a complete testing solution that automates the process of checking if software works correctly. Instead of testing applications manually every time, Katalon lets you create automated tests that run on their own.
The platform supports four main types of testing in one place: web applications, mobile apps (Android and iOS), APIs, and desktop programs. You can create tests using simple point-and-click recording, basic drag-and-drop actions, or by writing code if you prefer more control.
Katalon uses artificial intelligence to make testing easier. The AI can write test code from simple instructions, explain existing code, fix tests when websites change, and spot problems automatically. Tests can run on your computer or in the cloud.
