Stoplight makes API design really easy. The graphical interface is very intuitive to use. It can easily switch to the code view and back. Even it is a web interface it works realtime when having other instances open. The git integration is well done and style guide validation is helping in avoiding mistakes and keep uniformity across all API design.

The perfect example of how software should be. Review collected by and hosted on G2.com.

I've not come across real items I dislike. The only thing that could be really benefitial would be the option to have a so called API developer portal. A way to catalogue available API of the business and to mock them for users that don't count in the 'user' count. Another thing is the enormous price gap for the pro version. I could see this also as a pro because it means the most important features are available for a reasonable price, but rather would see the ability to select seperate features from the pro version without the need to completely move to the pro and paying the pro price.
