Excellent Addon. I was tired from the heavy Postman and I was searching for something light and powerful and I tested the API tester add-on for Chrome and it is perfect, allow me to save session and parameters and it is very efficient.
Simple tool for quick access to requests. For me, it's better than Postman for quick usage. Thanks to developers. No ads
This plugin offers a powerful and user-friendly interface for API testing, similar to popular tools like Postman. It supports extensive request customization, tabbed navigation for managing multiple requests, and the ability to save and organize requests. I like it since it could simplify my work of the troubleshooting web service.
This plugin looks useful for testing API. An interface is similar to popular tools, e.g. Postman. Wide request customization, tabs for every request, ability to save requests, dark theme. There is enough pros for everyone
This is a very handy extention for testing, especially the visible block for variables. And nothing unnecessary.
