Electron vs Tauri: Choosing a Framework for Your Desktop App

If you want a Windows and Mac desktop app built with web technology, the Electron vs Tauri decision comes up quickly. Both let your team write the interface in HTML, CSS and JavaScript, using the same frameworks you would use on the web, and ship it as an installable app. The difference is what sits underneath. Electron bundles its own copy of Chromium and Node.js into every app. Tauri uses the web renderer already built into the operating system and runs its backend logic in Rust.

That one architectural choice affects download size, memory use, how consistent the app looks across machines, which languages your team needs and how you handle security updates. This guide compares the two on the points that change cost, risk and time, then gives a plain decision guide.

Electron vs Tauri: the short answer

Pick Electron if you want the most predictable rendering on every machine, a large ecosystem and a team that works only in JavaScript or TypeScript. Pick Tauri if you want small installers, lower resource use and a stricter permission model, and you are comfortable adding Rust to the stack for the parts of the app that talk to the operating system.

Both are proven choices. Electron's showcase of apps includes Visual Studio Code, Slack, Discord, Figma and Signal. Tauri is younger, but it is stable, and it also targets Android and iOS from the same codebase.

How each framework works

Electron: Chromium and Node.js in the box

The Electron documentation describes it as a framework for building desktop applications using JavaScript, HTML and CSS that embeds Chromium and Node.js into its binary. That lets you keep one JavaScript codebase for Windows, macOS and Linux without native development experience. Every user runs the exact browser engine you tested against, and your backend code can use the full Node.js ecosystem.

Tauri: the system webview plus a Rust core

Tauri does not bundle a browser. According to its webview versions reference, it uses WebView2 on Windows, which is based on Microsoft Edge and therefore Chromium, and WebKit on macOS, iOS and Linux. WebView2 updates itself and comes preinstalled on Windows 11, and Tauri's installer handles it on older Windows versions. Application logic that needs system access is written in Rust and exposed to the frontend through commands.

Side by side: Electron vs Tauri

App size, memory and performance

Because Electron ships Chromium with every app, installers are large and each running app carries its own browser engine in memory. For a single, heavily used tool that users keep open all day, many people accept that trade. For a small utility, it can feel out of proportion.

Tauri's project site says that by using the OS's native web renderer, the size of a Tauri app can be as little as 600KB. Real apps are larger once you add assets and features, but the gap in the Electron vs Tauri comparison is usually large enough for users to notice on download and install. Runtime speed of the interface itself depends more on how the frontend is built than on the framework; a slow React screen is slow in either shell.

Rendering consistency and testing

This is Tauri's main trade-off. On Windows, WebView2 is Chromium-based and kept current, so behavior is close to Electron. On macOS, the app renders with WebKit, the engine behind Safari, and on Linux with the WebKit version the distribution provides. CSS and JavaScript features can behave differently between engines, so a Tauri app needs testing on each operating system rather than on one.

Security and maintenance

Security is where the two philosophies differ most. Electron gives the app Node.js power, which is convenient but means careless configuration can expose the file system or shell to web content. Tauri takes the opposite default: the frontend can only call the specific commands and permissions you grant. Either way, a desktop app that handles sensitive data deserves an independent review; our guide to penetration testing cost explains how that is scoped.

Maintenance follows from the architecture. Electron's release timelines state that the team supports the latest three stable major versions, with release dates tied to Chromium's schedule, so an Electron app needs a regular upgrade rhythm to keep receiving security fixes. A Tauri app inherits browser-engine updates from the operating system, but you still update the Tauri runtime, your Rust dependencies and your frontend packages.

Languages, skills and your team

An Electron app can be written entirely by a JavaScript or TypeScript team. A Tauri app's interface can be built by the same people, but anything that touches the operating system, such as files, native menus, background tasks or hardware, is typically written in Rust. That is a real hiring and review consideration. Many teams find a small amount of Rust manageable; others would rather stay in one language.

Frontend choices carry over directly in both cases. If your team already builds with React, the framework decisions in our Next.js vs React guide apply to the interface layer. If you are still deciding whether the product should be a desktop app at all, our comparison of PWA vs native apps covers when a web app is enough.

A simple decision guide

1. 01The app must render identically on every machine: choose Electron.
2. 02Your team works only in JavaScript or TypeScript and relies on Node.js libraries: choose Electron.
3. 03Install size and memory use matter, for example a tray utility or a tool deployed to many machines: choose Tauri.
4. 04You want a strict permission model by default: lean toward Tauri.
5. 05You want desktop and mobile from one codebase: evaluate Tauri, or a cross-platform mobile framework.
6. 06Performance or deep OS integration is the product itself: consider fully native Windows and macOS apps.

Build your Windows and Mac app with a senior team

The Electron vs Tauri choice is easy to make and costly to reverse once an app is in users' hands. We build custom Windows and Mac desktop applications, with Electron, with Tauri or fully native, and we recommend whichever fits your users, your team and your security needs. Our desktop and custom app development work comes with senior engineers, weekly demos and full ownership of the code from day one.

If you are planning a desktop app or weighing Electron vs Tauri for a rebuild, tell us what you are building. A senior engineer will reply within one business day with a straight recommendation.
