As answered by people managing StackSeed.dev and Mailflow.sh.
StackSeed.dev's answer
Filters that actually match how you'd search — by tech stack, category, price and payment provider — and pricing that's stated plainly, including whether something's open source, free, or paid. No account needed to browse.
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.
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.
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.
StackSeed.dev's answer
Next.js 15 (App Router), React 19 and TypeScript on the frontend, styled with Tailwind CSS v4.
