Hooklistener's answer

Hooklistener was born out of frustration. As developers, we were tired of using "disposable" webhook tools that lost critical data whenever we refreshed the page or closed the browser. We needed a tool that treated webhook debugging as a serious part of the development workflow—with persistence, security, and the ability to work together as a team. So, we built it.

Diffyn's answer:

I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.
