It has been a great Postman alternative for our team. We've struggled with postman pricing for a while, so tried APIDog and got all of features for the price of postman basic plan, which we signed prior.

The way the AIs are categorized, helping me to find the correct one. Also the AI app creation.

Apidog has all the steps of API designing, testing, documentation, etc on one platform which is a differentiator from other products. Especially having a separate window for test plan creation is very interesting and I like the ability to easily create a list of commands to run. I also really like the ability to reference other test cases from inside another. It can be used to create reusable scaffolding for common tasks.
