Architecture Differences
Electron Architecture
Electron bundles Chromium browser engine and Node.js runtime into every application creating a self-contained environment where the Main Process runs Node.js for system operations and application lifecycle, Renderer Processes run Chromium for each window rendering HTML/CSS/JavaScript, and IPC Communication connects main and renderer processes. The bundled Chromium ensures consistent rendering across platforms regardless of system browser versions but adds 100-150MB to every application. Node.js integration in renderer processes (when enabled) provides full system access but creates security vulnerabilities if handling untrusted content. Electron apps run multiple processes (main process + one renderer per window) consuming significant memory even for simple applications.
Tauri Architecture
Tauri uses the operating system's native WebView for rendering eliminating the need to bundle browsers where the Core Process runs Rust backend handling all system operations, WebView Process uses platform-native rendering (Edge WebView2 on Windows, WebKit on macOS, WebKitGTK on Linux), and IPC Bridge enables secure command-based communication between frontend and backend. Native WebView means zero rendering engine bloat in application bundles, automatic updates when OS updates its WebView, consistent rendering with other system applications, and significantly reduced memory usage. Rust backend provides memory safety without garbage collection, near-native performance, and secure-by-default architecture. Learn more about Tauri architecture details.

Bundle Size Analysis
| Application Type | Tauri Size | Electron Size | Difference |
|---|---|---|---|
| Hello World (minimal) | 3 MB | 150 MB | 50x smaller |
| Simple CRUD app | 4-5 MB | 160-170 MB | 35x smaller |
| Complex app (React, DB) | 8-10 MB | 180-200 MB | 20x smaller |
| Feature-rich (plugins) | 12-15 MB | 200-250 MB | 15x smaller |
Bundle size differences have significant real-world implications: Download Time - Tauri apps download in seconds vs minutes for Electron on slower connections; Disk Space - Installing 10 Tauri apps uses 50MB vs 1.5GB for Electron apps; Update Distribution - Smaller updates download faster encouraging users to stay current; Corporate Environments - Easier deployment in bandwidth-constrained enterprise networks; Storage-Limited Devices - Better suited for devices with limited SSD space.
Memory Usage Comparison
| Scenario | Tauri Memory | Electron Memory | Savings |
|---|---|---|---|
| Idle (background) | 30-50 MB | 150-200 MB | 75% less |
| Active use (single window) | 50-100 MB | 200-300 MB | 65% less |
| Multiple windows (3) | 100-150 MB | 400-600 MB | 70% less |
| Heavy processing | 150-200 MB | 500-800 MB | 70% less |
Startup Time and CPU Usage
Startup performance affects user experience significantly. Tauri applications start in under 1 second (cold start) and under 500ms (warm start) because they load minimal code, use native WebView (no browser initialization), and benefit from Rust's fast compilation. Electron applications start in 2-5 seconds (cold) and 1-2 seconds (warm) due to Node.js runtime initialization, Chromium engine startup, and larger codebase loading. CPU usage during idle is minimal for both frameworks, but Tauri's Rust backend handles intensive operations more efficiently than Node.js, making it better for CPU-bound tasks like image processing, data parsing, or cryptographic operations.
