Automated API penetration

The past 2 years I've built around 12 SaaS platforms (mainly for clients). I loved building them, especially the API's. The only thing I really hated was testing those API's for hours and hours to make sure they would handle all data thrown at them without crashing. So I started working on a way to automatically test all API endpoints with all kinds of different payloads :) I was wondering how other hunters were thinking about this tool? https://www.producthunt.com/upco...
