Kinde's answer

Diffyn's answer:
Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.
Kinde's answer
Kinde was born from a frustration of having to reimplement core features every time a new project was dreamt up. Things like customer authentication, feature flags, and billing are needed by almost every SaaS startup at some point with a variety of cloud based and self hosted solutions out there. Kinde's founders got together to reinvent how software companies get started with the ambition to help accelerate their product idea into a reality as fast as possible. All of them have multiple stories of building things in the past and having to reimplement the same features over and over. Why can't there be an affordable option that works with engineers and their team to get them off the ground faster. This is Kinde.
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.
Kinde's answer
Kinde is offering a horizontal platform to solve fundamental features needed by almost every SaaS startup. Customer authentication, feature flags, and billing. While there are lots of players in the market who do each of those very well, none of them seamlessly work together without manually building in the integration. Kinde's platform is solving those problems under one roof as simply and elegantly as possible. We want your experience to be as painless as possible, which also means that our engineers regularly rotate through our support channels to make sure that your questions are answered as fast as possible by the experts who built the platform.
