Makerkit.dev's answer:
Indie Hackers and Companies who want to launch quickly, without compromising on quality.
Makerkit.dev's answer:
Makerkit uses Next.js 15 (App Router), Supabase, React.js, Typescript and Stripe.
Makerkit.dev's answer:
Makerkit stands out by offering a truly modular architecture built with Turborepo, where core features like auth, billing, and notifications live in their own packages for better maintainability.
While most starters lock you into specific patterns or providers, Makerkit gives you flexibility with a multi-account system supporting both B2B and B2C scenarios, provider-agnostic billing, and edge-ready deployment options.
Beyond the basics, it includes production-ready features like multi-factor auth, real-time notifications, and team permissions - all built with Supabase, TypeScript, React Query, and modern tooling to make development a genuine pleasure.
Makerkit.dev's answer:
While other starters give you basic auth and a dashboard, Makerkit provides a genuinely modular foundation with the real features SaaS products need - like multi-factor auth, team permissions, real-time notifications, and provider-agnostic billing, all organized in clean, maintainable packages using Turborepo.
You get a first-class developer experience with TypeScript, React Query, and modern tooling, plus the flexibility to support both B2B and B2C scenarios, different payment providers, and edge deployment options.
Best of all, Makerkit is actively maintained with regular updates and responsive support, so you're building on a foundation that grows with your needs rather than painting yourself into a corner.

Polygon.io gives you 5 API calls/minute on the free tier. Thatโs rough for options scanning since you need one call per expiration per symbol. Iโd only recommend this if youโre scanning fewer than 20 symbols. - Source: dev.to / 4 months ago
