Everything you need to ship

Production-ready features, not a TODO list.

Authentication that just works

Sign-in, sign-up, social login, SSO — all wired up with route protection and auto user sync. Zero config needed.

Payments, handled

Stripe subscriptions with checkout, billing portal, and production-tested webhooks. Three plans pre-configured. Start charging from day one.

A dashboard your users expect

Sidebar navigation, settings, billing management, loading states. Responsive and polished. Your users feel at home instantly.

Admin panel with real metrics

User management, subscription metrics, MRR tracking, plan distribution. Know your business from day one, not day ninety.

Emails that actually send

Welcome emails, subscription notifications — all built with React Email and Resend. Beautiful templates you can extend in minutes.

Blog that drives traffic

MDX-powered blog with frontmatter, tags, and full SEO metadata. Write content that ranks on Google and brings in organic users.

Dark mode, native

System-aware with manual toggle. CSS variables make theming effortless. Consistent across every page, every component.

SEO that ranks

Dynamic sitemap, robots.txt, Open Graph, Twitter Cards, structured metadata. Your pages are discoverable from the first deploy.

AI-native development

CLAUDE.md, .cursorrules, and Copilot instructions included. Your AI coding assistant understands the entire codebase from the first prompt.

Frequently asked questions

What exactly do I get after purchase? +

You get instant access to the private GitHub repository containing the full source code (53+ files in TypeScript), all documentation (deployment, architecture, customization guides), AI configuration files for Claude, Cursor, and Copilot, and the 25+ prompts library. You can clone it immediately and have a running application within minutes.

Can I use this for client projects? +

The Starter license allows 1 commercial project. The Unlimited license allows unlimited projects, including client work — perfect for freelancers and agencies who build SaaS products regularly. You keep full ownership of everything you build.

Is there a refund policy? +

Yes. 30-day money-back guarantee, no questions asked. If SaaS Starter doesn't save you time, email us and we will refund your purchase in full. See our refund policy for details.

Can I see a live demo? +

Yes. Visit demo.saas-starter.com to see the starter in action. You can explore the landing page, authentication flow, dashboard, admin panel, and blog — everything that ships out of the box.

Are updates free? +

Yes, forever. When Next.js, Clerk, or Stripe release new versions, the starter gets updated. You have access to all future updates through the GitHub repository at no extra cost.

Do I need to pay for the third-party services? +

Clerk and Resend have generous free tiers that cover most early-stage projects. Stripe only charges per transaction (no monthly fee). Vercel offers free hosting for personal projects. You can realistically launch with zero fixed costs beyond this purchase.

How is this different from free templates? +

Free templates are starting points with TODOs everywhere. SaaS Starter is a finished product: webhooks actually work and handle edge cases, the admin panel shows real metrics, dark mode is consistent across every component, SEO is fully configured, and AI assistants understand the entire codebase. You save 6+ weeks of tedious integration work.

What if I need help? +

The documentation covers everything: setup, deployment, customization, and troubleshooting. Unlimited plan includes priority email support with a 24-hour response time. The AI prompts library also helps you solve most issues by giving your coding assistant the right context.

Stop building boilerplate

Every week you spend on boilerplate is a week you are not shipping your product. Get the foundation right, then focus on what makes your SaaS unique.
