Case Study: Vaadin achieves instant reloads and 10% daily time savings with ZeroTurnaround's JRebel

Vaadin - Customer Case Study

Vaadin Ltd, the Finnish company behind the popular Vaadin Framework used by thousands of developers worldwide, faced a productivity drain from slow application redeploys. With a 60+ developer team and redeploy times of 20 seconds to over a minute, developers often limited testing to a couple of redeploys per hour, which disrupted workflows, reduced immediate feedback and increased the risk of coding “blind.”

Vaadin adopted JRebel across IDEs, build tools and application servers to enable instant class reloading and preserve UI state during reloads. This let developers test changes every minute instead of every half hour, increased reloads from about 2 redeploys/hour to roughly 60 instant reloads/hour, and delivered measurable productivity gains—around a 10% daily time savings—along with fewer bugs and a smoother development experience.
