I like that we can use it to create tests very quickly, so they are more reliable than manual ones! It also has some useful reports about what was really tested during each test execution in order of importance; this helps me prioritize things when writing new features or fixing bugs faster. The price could be lower as well if you go pro and get all its addons/customizations included - there's nothing free anymore after 1 year subscription expires by default unless paid annually then 2 years etc.). Also please make sure your system meets minimum requirements listed at https://gatlinvcenter.com/. We needed something fast which allowed us not only write unit / end2end functional user acceptance but full stack level regression suite too to ensure our product works flawlessly across browsers + mobile devices using different versions including iOS6+. The ease of use, the fact that it works well with microservices architecture and that it has a great plugin ecosystem to extend its functionality for any need. I have no issues with this product so far. It's been about 2 months since we started using it in our project, but everything went smooth. Nothing at all. We are using it to test our APIs and services before deploying them into production.
