Pros & Cons from Real Users Pros API Tester is free. The best GraphQL editor I ever saw. It gives the option to run literally any type of API. Easy import options. Pleasant user experience overall. Learning how to use the app wouldn't take too long. Application is pretty simple, straightforward and works well. Validating Restful and SOAP APIs, WebSocket applications, as well as GraphQL applications has been a good experience using API Tester. All the underlying challenges that come to mind for testing backend applications are well served. What is more important - it's completely free and all features are available without any fees. This mobile app increased my productivity, and I can test APIs from anywhere on the planet using only a mobile device. Cons Not optimal for fully automated testing, but it would be unfair to demand this from a mobile solution. The only cons is the lack of a desktop version. I think it could replace my other desktop alternatives.	Pros & Cons from Real Users Pros What I liked most about Testsigma is its intuitive Drag & Drop interface, which simplifies test creation and makes it accessible for both technical and non-technical users. The powerful mobile app and REST API testing features are also standout aspects. 1. Possibility to create autotests without programming knowledge 2. It takes not a lot of time to learn how to set up your project 3. Quick response of support team to any concerns 4. Constant development of product 5. Wide variety of settings to create, execute test cases 6. Presence of API testing 7. Cross browser, cross platform testing 1) With the minimum training users can handle the application. That is a unique feature in Testsigma. 2) Test step grouping is one more unique feature that helps to reduce the time to develop new scripts. - Easy to learn and use - Allows use of custom functions - Ability to reuse elements and steps - Bundling of test cases and test plans - Scheduling runs - Automatic rerun of failed cases - API testing - JIRA Integration Can be sued with simple English Multiple OS and browser versions Very simple, even someone non-technical person can perform automation Cons While Testsigma is generally very efficient and user-friendly, there are occasional moments when the platform can feel a bit slow during peak usage times. However, these instances are rare and do not significantly impact overall productivity. 1. Sometimes presence of bugs, instability in product which can cause some inconvenience Most of the features are good, with no cons at the moment. Need to improve on: - Better communication on changes - removal of certain symbols from UI identifier names, changing test plan run settings, deprecating certain test steps, etc. cause more maintenance and upkeep. - Need detailed release notes So far it is working great.I have no issues with it
