Modern desktop development has evolved with frameworks that leverage web technologies to deliver native experiences. In this session, we’ll explore building cross-platform desktop applications using Electron and Tauri through a real-world case study. You’ll discover how Electron’s Node.js/Chromium stack compares to Tauri’s Rust-powered, lightweight binary approach. We’ll cover key differences in bundle size, startup time, memory usage, and rendering behavior across Windows, Linux, and macOS. Live coding demos and performance benchmarks will illustrate best practices for secure, efficient app development. Attendees will leave with practical insights into selecting the right framework, optimizing performance, and tackling common challenges in cross-platform desktop development.
