Stoplight is a really great documentation tool, but when I create my API specification or documentation, I need to ensure the params, the endpoint, etc, in my doc can totally work for everyone. In this case, I need to debug the API endpoints as well, but Stoplight doesn't provide me with a powerful debugging tool.
So I migrated to Apidog, with Apidog, I can design my APIs, generate beautiful documentation, and share them with others like Stoplight does, and I can also debug my API in a very convenient way like using Postman.
I would say that Apidog is a combination of Postman and Stoplight, with Apidog, I don't need to switch several tools at the same time. I can use it for API designing, documentation, testing, and even automated testing. It's really comprehensive tool in the API field I had never ever met.
