Real use case example

"A founder wants to build a minimal online marketplace. They pick TanStack template, copy the code, and set up their SaaS project on Heroku. They implement user authentication and connect their PostgreSQL database in about 1-2 hours. Now their marketplace has a smooth sign-up process."

When to use it

•You're building a scalable web application and need a solid foundation quickly
•You want to simplify the process of setting up authentication and database connections
•You need a consistent and visually appealing UI without spending too much time on design
