How Eduten Built a High-Usage Learning Platform with Vaadin

Eduten, a browser-based math learning platform built on nearly two decades of University of Turku research, serves over 3 million users across 50+ countries and 70% of Finnish schools. The team chose Vaadin's full-stack Java approach with Hilla to unify frontend and backend development, reduce cloud hosting costs, and support offline use. The result is a mobile-first, gamified platform that handled over 2 billion math exercises in Mongolia alone in 2024, while remaining maintainable for a small engineering team.
