StackSeed.dev's answer

Developers starting a new project — a SaaS, a directory, a landing page — who'd rather spend a few minutes filtering by stack and budget than an afternoon comparing options scattered across GitHub and blog posts.

Diffyn's answer:

Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.

StackSeed.dev's answer

Started as a personal tool to stop re-doing the same research — comparing starter kits scattered across GitHub, Twitter and blog posts — every time a new project began.

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.
