Electron fits teams that want a mature, JavaScript-only toolchain and can accept a heavier install; Tauri fits teams that want a smaller, faster app and are willing to write some Rust. Tauri 2.0, released in October 2024, added iOS and Android targets on top of desktop, closing part of the gap that used to separate it from Electron's broader reach.
| Dimension | Electron | Tauri |
|---|---|---|
| Bundle size | Ships Chromium and Node.js inside every build; installers commonly land between 100MB and 300MB | Uses the OS's own webview instead of bundling one; typical apps install at 3MB to 10MB |
| Memory footprint | Chromium and Node.js reserve a large chunk of RAM before any app code runs, often 100MB or more at idle | Runs on a Rust backend plus the system webview, so idle memory use is usually in the tens of megabytes |
| Rendering engine | Bundled Chromium, identical on every OS, paired with a Node.js runtime for backend logic | System webview: WebView2 on Windows, WKWebView on macOS, WebKitGTK on Linux, paired with a Rust backend |
| Backend language | JavaScript or TypeScript through Node.js, with full access to npm | Rust for backend commands, called from a JavaScript or TypeScript frontend |
| Maturity and ecosystem | Public since 2013, powers VS Code, Slack, and Discord; deep npm package coverage and a large support base | 1.0 shipped in June 2022, 2.0 arrived in October 2024; smaller crates.io ecosystem that is growing but has fewer prebuilt integrations |
When does Electron make more sense?
Electron is the safer pick when a team already ships a web app and wants the desktop version to reuse that exact codebase and its npm dependencies. Its Chromium runtime is the same across Windows, macOS, and Linux, so there is no need to test against different webview versions per platform. The ecosystem also carries a decade of Stack Overflow answers, plugins, and hiring pool depth that a newer framework cannot match yet.
When does Tauri make more sense?
Tauri suits teams that care about install size and idle memory more than they care about avoiding Rust. Because it calls the operating system's own webview instead of bundling one, it skips the Chromium download entirely, which is why its installers land in single-digit megabytes instead of hundreds. The tradeoff is that behavior can vary slightly between WebView2, WKWebView, and WebKitGTK, since each is a different rendering engine with its own quirks.
Which one fits your team?
Pick Electron if the team is JavaScript-only, needs a big npm ecosystem, or is porting an existing web app with minimal changes. Pick Tauri if the app needs to stay small, start fast, and run light on memory, and the team can either write Rust or keep the backend thin enough that a contractor can handle it. Neither framework is obsolete: Electron still runs some of the most-used desktop software in the world, and Tauri is the newer option for teams optimizing for footprint over ecosystem size.
