Launching a web app begins by outlining user roles, essential use cases, and the data structure. A robust MVP emphasizes core pathways, intuitive navigation, and consistent UI elements, enabling rapid delivery without evolving into a fragile collection of ad-hoc screens.

Post-launch, scalability and dependability are paramount: performance budgets, caching strategies, secure login, and tidy API agreements. With adequate monitoring, CI/CD practices, and well-designed architecture, teams can iterate more quickly while maintaining code stability as features and traffic increase.
