Tauri 2.0 offers high efficiency for cross-platform app development

Tauri 2.0 is emerging as a highly efficient alternative to cross-platform frameworks like Electron and Flutter. By utilizing system webviews such as WebView2 on Windows or WebKit on macOS, Tauri achieves significantly smaller installer sizes and lower resource consumption. For example, a Tauri hello world installer is approximately 3.2 MB, which is 96% smaller than the 85 MB required by Electron 43. Additionally, Tauri demonstrates faster cold-start times and lower idle memory usage compared to Electron.

While Flutter offers advantages in consistent GPU rendering, Tauri is noted for superior CPU and memory efficiency, making it suitable for applications focused on forms, tables, and content. However, the Linux experience with WebKitGTK has been noted as having performance and support challenges.

The shift toward these more efficient frameworks is also being accelerated by AI. Developers have successfully used AI tools like Claude to port entire applications from Electron to Tauri in under 24 hours, even without prior knowledge of the Rust programming language used in Tauri's backend.
