Why should a person choose your product over its competitors?

How would you describe the primary audience of your product?

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.

What makes your product unique?

StackSeed.dev's answer:

StackSeed is a curated directory of developer starter kits — filter by tech stack, category, price and payment provider to find the one that actually fits your project, instead of losing an afternoon scrolling GitHub. Every listing is upfront about whether it's open source, free, or paid.

What's the story behind your product?

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.

Which are the primary technologies used for building your product?

StackSeed.dev's answer:

Next.js 15 (App Router), React 19 and TypeScript on the frontend, styled with Tailwind CSS v4.
