Free-tier cold start

Warming up the BamBanking API…

This demo runs on Render (free tier) with a Spring Boot backend and a cloud database. When the service has been idle, it needs a short moment to “wake up” (usually around 20–30 seconds). While that happens, the BankingApp login and dashboard can show loading states.

  • Backend: Java + Spring Boot
  • Frontend: Vanilla JS + Thymeleaf + custom UI
  • Database: MongoDB Atlas (cloud)
  • Hosting: Render free tier with cold-start
