As answered by people managing FreeFormatter and Cheapstack.dev.
Cheapstack.dev's answer:
Next.js 16, TypeScript, Tailwind CSS v4, Drizzle ORM, NextAuth v5, Polar.sh, Stripe, and Playwright.
Cheapstack.dev's answer:
One-time pricing starting at $19 with Polar.sh payments that work in 130+ countries, while competitors charge $199-$649 and require Stripe (46 countries only).
Cheapstack.dev's answer:
Lower price (80% less than ShipFast/MakerKit), Polar.sh for global payments, all 8 kits available in a $79 bundle, and built with latest Next.js 16.
Cheapstack.dev's answer:
Indie developers and bootstrapped founders building SaaS products on a budget, especially those outside Stripe-supported countries.
Cheapstack.dev's answer:
Built by a solo developer who couldn't use most boilerplates because they required Stripe (unavailable in many countries). CheapStack solves this with Polar.sh payments.
