Building an MVP in a weekend used to be a stunt. In 2026, it's the new normal — AI coding tools + curated OSS stacks make 48-hour builds genuinely possible.
This is the exact stack I'd use, with one-line install commands and the curator takes for each pick.
The 48-hour breakdown
| Hours | What you do |
|---|---|
| Hour 0-4 | Pick stack + scaffold project |
| Hour 4-12 | Build core feature (let AI handle most of it) |
| Hour 12-20 | Add auth + payments |
| Hour 20-30 | Build UI + polish |
| Hour 30-40 | Deploy to production |
| Hour 40-48 | Test + ship + announce |
The exact stack — full picks
1. Frontend framework: Next.js 15
pnpm create next-app@latest my-mvp --typescript --tailwind --appNext.js is the right default. App Router, Server Components, edge runtime, Vercel/Railway deploys in one click.
**Alternative:** Astro if your MVP is content-heavy (a blog, marketing site, docs).
Full Next.js vs Astro comparison.
2. UI components: shadcn/ui
pnpm dlx shadcn@latest init
pnpm dlx shadcn@latest add button card dialog form input tableshadcn/ui gives you copy-paste primitives. Beautiful defaults, accessibility baked in, no npm dependency to break.
**Alternative if you want pre-styled:** Mantine (more components out of the box).
For animations: Motion (Framer Motion):
pnpm add motion3. Backend: Supabase
pnpm add @supabase/supabase-js @supabase/ssrSupabase gives you Postgres + Auth + Storage + Edge Functions in one platform. Free tier covers you to ~1,000 users.
Why not just use Next.js API routes + a separate DB? You can. But Supabase saves you 4-6 hours of auth setup and gives you Row-Level Security baked in.
4. Auth: Built-in via Supabase
Supabase Auth supports email + magic links + OAuth (Google, GitHub, Apple) out of the box.
const { data, error } = await supabase.auth.signInWithOAuth({
provider: 'google',
options: { redirectTo: `${window.location.origin}/auth/callback` }
});If you're not using Supabase, **Better Auth** is the modern 2026 pick.

5. Database / ORM: Drizzle
pnpm add drizzle-orm
pnpm add -D drizzle-kitDrizzle is the modern TypeScript-first ORM. Edge-compatible, zero runtime overhead, SQL-like syntax.
**Alternative:** Prisma — better DX, heavier runtime. Pick Prisma if DX matters more than performance.
6. Forms: React Hook Form + Zod
pnpm add react-hook-form zod @hookform/resolversReact Hook Form for state, Zod for validation. The dominant 2026 form stack.
7. AI integration: Vercel AI SDK
pnpm add ai @ai-sdk/anthropic @ai-sdk/openaiThe Vercel AI SDK handles streaming, structured outputs, tool calling for any LLM (Claude, GPT, Gemini, local Ollama).
For development, use Ollama to run Llama 3.3 locally:
ollama run llama3.3For agents (multi-step LLM workflows): LangChain, LlamaIndex, or Mastra (JS-first).
Open-source AI agent frameworks compared.
8. Payments: Razorpay (India) or Stripe (global)
If India-first: pnpm add razorpay. UPI + cards + subscriptions.
If global: Stripe. Same simplicity.
Critical: verify webhook signatures server-side. Skipping this is the #1 payment bug in indie SaaS.
9. Email: Resend + react-email
pnpm add resend react-emailreact-email lets you write email templates in JSX. Resend handles delivery. Free tier covers 3,000 emails/month.
10. Deployment: Vercel or Railway
Vercel if you're Next.js-only and don't need long-running backend processes. Free tier is generous.
Railway if you have workers, cron, or websockets. Pay-as-you-go.
Skip AWS until you have real product-market fit. The complexity will eat your weekend.
The 48-hour timeline
Hours 0-4: Pick + scaffold
# Create the app
pnpm create next-app@latest my-mvp --typescript --tailwind --app
cd my-mvp
# Install everything
pnpm add @supabase/supabase-js @supabase/ssr drizzle-orm react-hook-form zod @hookform/resolvers motion ai @ai-sdk/anthropic resend react-email
# UI primitives
pnpm dlx shadcn@latest init
pnpm dlx shadcn@latest add button card dialog form input table sonnerSet up Supabase project. Create one DB table for your core entity. Set up RLS policy (auth.uid() = user_id).
Hours 4-12: Build core feature with AI
Open Cursor or Cline. Describe your core feature in 2-3 sentences. Let AI write the first pass. Review + fix.
**Pro tip:** paste the **Ship a SaaS bundle** into your AI agent's context. It knows the stack and writes code consistent with it.
Hours 12-20: Add auth + payments
Auth: Supabase Auth UI components handle the whole sign-in/sign-up flow.
Payments: Stripe Checkout or Razorpay Standard Checkout. ~30 lines of code total.
Hours 20-30: UI + polish
Apply shadcn components. Add Motion animations on key transitions. Use Lenis for smooth scroll on landing page.
Hours 30-40: Deploy
# Vercel
pnpm dlx vercel
# Or Railway
pnpm dlx railway upSet env vars. Connect domain.
Hours 40-48: Test + ship + announce
End-to-end test (sign up → use feature → pay → success).

What you don't do in 48 hours
Be honest about scope:
- Don't write tests. Real users find bugs faster than you can write tests. Launch first.
- Don't polish to perfection. v1 should embarrass you. v3 should embarrass you less.
- Don't add features beyond core. Settings page, profile editing, dark mode — all v2.
- Don't optimize performance. Optimize for the first 100 users, not 100k.
