In the world of cross-platform desktop app development, Electron has long been the go-to choice for developers who want to build powerful applications using JavaScript, HTML, and CSS. But with the rise of Tauri, a new contender built with Rust, many are asking: Is it time to start relying on Tauri instead of Electron? Let’s dive into the strengths and weaknesses of both frameworks and see what the future holds.
What Is Electron?
Electron is an open-source framework that allows you to build native desktop applications using web technologies. By embedding Chromium and Node.js, Electron lets you create apps that run on macOS, Windows, and Linux with a single codebase. It’s trusted by industry giants—apps like Visual Studio Code, Slack, Figma, and even ChatGPT are all built on Electron. Its robust API gives you access to native OS features, automatic updates, crash reporting, and easy packaging for distribution across popular app stores.
What Is Tauri?
Tauri is a modern framework for building cross-platform desktop applications. Unlike Electron, Tauri leverages your system’s native web renderer and is powered by Rust, a language known for its performance and security. Tauri supports any frontend framework, so you can bring your existing web stack without changes. It also allows you to write application logic in Rust and integrate deeply with the OS using Swift or Kotlin. Tauri apps are remarkably lightweight—their size can be as small as 600KB—and the framework prioritizes security at every level.
Electron vs. Tauri: Key Differences
- Performance and Size: Electron apps are known for their stability and rich features but can be heavy, often exceeding 100MB in size. Tauri, by contrast, creates apps that are much smaller and faster, thanks to Rust and native rendering.
- Security: Electron’s security is tightly coupled with Chromium updates, ensuring rapid patching. Tauri, built with Rust, is designed with security as a top priority, minimizing attack surfaces.
- Cross-Platform Support: Both frameworks support Windows, macOS, and Linux. Tauri goes further, offering support for Android and iOS, making it a true cross-platform solution.
- Ecosystem and Community: Electron has a mature ecosystem with extensive documentation and community support. Tauri is newer but rapidly growing, with a focus on modern development practices.
- Development Experience: Electron’s integration with Node.js and npm makes it easy for JavaScript developers, while Tauri’s Rust backend may have a steeper learning curve but offers more control and efficiency.
Should You Switch to Tauri?
Tauri is a promising alternative for developers who care about app size, performance, and security. If you’re building a new app and want the smallest possible footprint, or you’re targeting mobile platforms as well as desktop, Tauri is worth serious consideration. However, Electron’s maturity, extensive tooling, and proven track record make it a safe choice for complex, enterprise-grade applications.
Conclusion
While Electron remains a powerful and reliable framework for cross-platform desktop apps, Tauri’s innovative approach is hard to ignore. As Tauri’s ecosystem matures, it’s becoming a viable alternative—especially for projects where performance, security, and minimal size are top priorities. For now, the choice depends on your project’s needs, but keep an eye on Tauri as it continues to evolve.
