Technology choices made at the MVP stage follow you for years. The wrong stack means expensive migration, developer onboarding friction, and architectural debt that compounds with every feature you add. The right stack means a fast first build, clean handover to your first engineer, and a foundation that scales comfortably to Series A and beyond. This article explains the stack we use for every Two Bit Digital MVP build — and why each choice was made.
The Stack at a Glance
- •Framework: Next.js 14 (App Router) with TypeScript
- •Backend/Database: Supabase — PostgreSQL with Row-Level Security, auth, and storage
- •Deployment: Vercel — global CDN, zero-config CI/CD from GitHub
- •Styling: Tailwind CSS
- •Payments (where in scope): Stripe
- •Email (where in scope): Resend or SendGrid
- •Analytics: Posthog or Google Analytics 4
Next.js 14: The Application Layer
Next.js is the standard for production React applications in 2025. The App Router, introduced in Next.js 13 and matured in 14, gives you server components, server actions, file-based routing, streaming, and built-in API route handlers. The practical benefits for an MVP: server components reduce JavaScript sent to the browser (faster initial loads), server actions eliminate the need for a separate API layer for simple mutations, and the file-based routing means any React developer can navigate the codebase immediately. It is also the best framework for SEO — server-side rendering produces fully indexable pages without client-side hydration.
TypeScript: Not Optional
TypeScript is not a preference. It is a requirement for any production SaaS. Type safety catches bugs at compile time that would otherwise surface as runtime errors in front of users. When you bring on your first engineer, TypeScript makes the codebase self-documenting — every function signature tells them what inputs are expected and what outputs are returned. At Two Bit Digital, we generate TypeScript types directly from the Supabase database schema using the Supabase CLI. This means the types for every table, view, and function are always accurate and up to date.
Supabase: The Complete Backend
Supabase provides a PostgreSQL database, an authentication service, file storage, and real-time subscriptions — all from a single managed platform. The critical feature for SaaS is Row-Level Security (RLS): database-level policies that restrict data access per user, enforced independently of application code. This means a bug in your application cannot expose another user's data. We enable RLS from day one, not as an afterthought. Supabase is also open source — the entire stack can be self-hosted on AWS or GCP if you ever need to move off their managed service.
Vercel: Zero-Config Deployment
Vercel is the deployment platform built by the creators of Next.js. Connect your GitHub repository, and every push to main triggers an automatic production deployment. Every pull request gets a preview URL for review. The global edge network means your application loads quickly from anywhere in the world. The operational value for an MVP: you spend zero time on server configuration, certificate management, or auto-scaling setup. That time goes into product instead.
Tailwind CSS: Maintainable Styling
Tailwind's utility-first approach means styling is co-located with markup. Any developer can open a component and immediately understand what it looks like without reading a separate CSS file. The production build purges unused utilities, keeping the CSS bundle small. We do not use component libraries (Material UI, Chakra) as they create an upstream dependency with opinionated patterns. Tailwind gives complete control without runtime overhead.
Why This Stack Ships in 10 Days
The 10-day timeline is possible because this stack eliminates infrastructure decisions. There is no server to configure, no database cluster to provision, no deployment pipeline to build. Supabase handles auth — we do not write authentication logic. Vercel handles CI/CD — we do not write deployment scripts. TypeScript and the Supabase schema generator handle type safety — we do not manually maintain interface definitions. Every day that would otherwise be spent on infrastructure is spent on product features.
