Hey PH! 👋 Marcos here, maker of FounderKit.
I built this because I kept wasting 2 weeks on the same foundation every time I started a new SaaS — auth, Stripe, admin panel, emails. Over and over.
So I packaged everything I always want from day one into a single boilerplate.
The thing that bugged me most about existing solutions like ShipFast: no admin panel, no email templates, and $199. So I built FounderKit with all of that for $99.
What's included:
→ Clerk auth (OAuth, magic links, user management)
→ Stripe subscriptions + full webhook handling
→ Admin panel with MRR stats and user table
→ 4 React Email templates (welcome, upgrade, failed payment, cancellation)
→ MDX Blog
→ Dynamic OG image generation
→ Waitlist mode
→ Demo mode (no DB or auth needed to preview)
Stack: Next.js 16 · Clerk · Stripe · Drizzle · PostgreSQL · Resend · Tailwind v4
Setup takes ~30 minutes from download to live on Vercel.
Happy to answer any questions about the implementation or the stack. Would love your honest feedback :).
