I've developed a SaaS starter that prioritizes best practices: - Backend built with hexagonal architecture - Frontend structured with the Refine framework It offers a comprehensive set of features: 🔒 Multi-tenancy support 💳 Seamless integration with Stripe for payments 🌐 Infrastructure as Code...
StackSeed is a directory of developer starter templates — filter by tech stack, category, price and payment provider instead of scrolling GitHub for hours. Free and premium boilerplates side by side, with the real tradeoffs (open source vs. paid) made explicit.

As answered by people managing Widin.io and StackSeed.dev.
Widin.io's answer
We use the Refine framework to help you easily create advanced and organized frontend features.
On the backend, we structure the codebase using Hexagonal Architecture best practices. This approach is crucial for a SaaS platform to effectively deliver advanced features.
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.
Widin.io's answer
Widin is the only starter that focuses on hexagonal architectures. It helps to start quickly but also to stay on the right track over time.
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.

Startup CTO launching a new 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.
Widin.io's answer
Having built several SaaS web apps from scratch, I developed over and over similar features. Trade-off between velocity and clean architecture are sometime made, while undesirable. Widin aims to provide a solution to that compromise.
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.
Widin.io's answer
Next.js, React.js, Typescript, Refine, Next Auth, GraphQL, GraphQL Codegen, Nest.js, Passport, CASL, Zod, Prisma, PostgreSQL, Vercel, Render.
StackSeed.dev's answer:
Next.js 15 (App Router), React 19 and TypeScript on the frontend, styled with Tailwind CSS v4.
