The technology choices you make at the start of your startup journey will shape your ability to move fast, attract talent, and scale without expensive rewrites. The wrong stack can cost you 12–18 months of velocity when you can least afford it.
Frontend: Next.js + TypeScript
Next.js handles server-side rendering, static generation, and API routes in one framework. TypeScript adds type safety that pays dividends as your codebase grows.
Backend: Node.js or Python + FastAPI
For most startups, Node.js with NestJS provides the best balance of performance and developer availability. If you're building AI/ML features, Python with FastAPI is the natural choice.
Database: PostgreSQL first, always
Start with PostgreSQL. It's relational, battle-tested, supports JSON natively, and scales to billions of rows with proper indexing. Add Redis for caching and session management.
Infrastructure: Vercel + AWS/GCP
Deploy your Next.js frontend on Vercel — zero configuration, automatic CDN, instant rollbacks. Run your backend and databases on AWS or GCP using managed services.
Auth: Supabase Auth or Auth0
Never build authentication from scratch. Supabase Auth is free for early-stage startups and integrates with PostgreSQL natively.
