Desktop App Development with Tauri: Faster, Lighter, Safer

We develop desktop applications using Tauri, a modern framework that provides a faster, lighter, and more secure alternative to Electron. Our team has delivered 30+ projects combining Rust and WebView, including migrations of large Electron apps. The result: apps that weigh 4–15 MB, consume 30–60 MB of RAM, and provide maximum security through safe Rust code. For a typical desktop app, development costs start from $5,000 and can reach $20,000 for complex projects, offering substantial savings compared to Electron.

Why Tauri is faster and safer than Electron

A Tauri app consumes 2–4× less memory than an Electron app with comparable UI performance. The installer size savings reach up to 10×. The lightweight app architecture relies on zero-cost abstractions and Rust's RAII pattern.

What problems does Tauri solve?

Size and loading speed. Users don't want to download 150+ MB for a simple chat or organizer. Tauri slashes the installer size by 10×. Download and installation take seconds.

Security. All critical code (file handling, networking, system calls) runs in Rust. The frontend has no direct OS access — only through explicitly exposed commands and a capability-based security model. Rust is a language with memory safety guarantees, which eliminates entire classes of vulnerabilities.

Performance. The Rust backend runs at native speed, and the absence of extra JS bridge layers reduces latency. TTFB and UI rendering are faster than in Electron. For Rust desktop development, Tauri offers unmatched performance.

How we build a Tauri app: process and examples

The process consists of five stages: analysis and design, MVP prototyping, Rust backend development, integration and testing on all platforms, deployment and distribution (CI/CD, code signing).

A real‑world example: We migrated an expense‑tracking app from Electron to Tauri. The original installer of 140 MB shrank to 9 MB. Memory usage dropped from 180 to 45 MB. The backend was rewritten in Rust: commands for file handling, notifications, and system tray integration. The frontend (React) stayed untouched.

Basic project template:

npm create tauri-app@latest # Choose: TypeScript, React, Vite 

A Rust command:

#[tauri::command] async fn increment(state: State<'_, AppState>) -> Result<i32, String> { let mut counter = state.counter.lock().map_err(|e| e.to_string())?; *counter += 1; Ok(*counter) } 

Call from the frontend:

import { invoke } from '@tauri-apps/api/core'; const count = await invoke('increment'); 

Quick start steps for Tauri development

1. Install Rust and Node.js.
2. Run npx create-tauri-app and choose your frontend framework.
3. Write Rust commands with #[tauri::command] and manage state via State.
4. Build and sign the app with npm run tauri build.

How long does development take?

Timelines range from 2 to 8 weeks depending on complexity. A simple app with a few commands and basic UI takes about 2 weeks. A complex one with system API integration, updater plugin, and multi‑window support takes up to 8 weeks. The cost is calculated individually after requirements audit. On average, our turnkey Tauri development is 30–50% cheaper than Electron thanks to less code and no need to bundle Chromium.

How does Tauri ensure security?

Security is built on two levels. First, Rust guarantees memory‑safe code: the compiler checks everything at build time, eliminating null pointers and memory leaks. Second, the capability system restricts frontend access to OS APIs. Even if an attacker gains control over the interface, they cannot read files without explicit permissions in the config:

{ "permissions": [ "core:default", "fs:allow-read-text-file", "dialog:allow-open" ] } 

What's included in the work?

• Requirements analysis and architecture design.
• Rust backend development with async commands and zero-cost abstractions.
• Frontend integration (any web framework) for a true cross-platform app.
• Configuration of the permission system and platform‑specific features.
• Build and code signing for Windows, macOS, Linux.
• API documentation and operation instructions.
• Post‑launch support (optional).

Common pitfalls in Tauri development

• Incorrect async handling: commands must be async if they use I/O.
• Forgetting to declare permissions in capabilities — the frontend gets access errors.
• Using slow synchronous operations on the main thread — blocks the UI.
• Ignoring platform-specific WebView quirks (e.g., macOS doesn't support some CSS properties).
