Neither framework is safe by default in every respect. Electron ships its own browser engine and relies on you to keep it updated and configured. Tauri uses the system webview and has a built in permission model, but you still own your Rust code and frontend dependencies. Choose by the risks you can manage.
Engine and patching
Electron bundles Chromium and Node.js. You control the version and you are responsible for shipping updates. The Electron docs say older versions have more publicly known exploits, so an app that is not upgraded regularly falls behind browser fixes.
Tauri relies on the operating system's webview. Its docs argue that webview and OS maintainers patch faster, on average, than app developers who bundle an engine. The cost: you cannot ship a fix for a webview bug, and behavior differs across user machines.
Privilege model
Electron relies on process settings: node integration off, context isolation and sandbox on, a narrow preload bridge, and sender checks in the main process. Mistakes here are configuration mistakes.
Tauri starts from a split between a trusted Rust core and a webview that reaches only what capabilities expose. Scopes narrow commands. By default, though, registered commands are callable from all windows, so you still need to restrict them.
Packaging and tamper checks
Electron offers fuses and ASAR integrity validation for macOS and Windows. Tauri's updater requires signatures on updates, and both ecosystems depend on OS code signing for trust at install time.
Dependencies
Both pull a large frontend dependency tree from npm. Tauri adds Rust crates. Electron adds Node modules in the main process. A compromised package in either tree ends up inside your app, so inventory both sides.
Decision guide
- Small team, web frontend, wants strong default separation: Tauri's model gives a head start, if you accept webview variance and Rust.
- Need identical rendering everywhere or deep Node integration: Electron fits, and you must invest in hardening and upgrades.
- Handling regulated or sensitive local data: whichever you pick, budget for review of every command or IPC handler.
Other factors, such as team skills and plugin needs, may decide the question before security does, and that is fine as long as you do the hardening work. See the posts on Electron defaults and Tauri's model.
Try it yourself
Click through it at your own pace, or open it full screen.
Open the inventory and look at how many packages arrive indirectly. Both frameworks pull a large frontend tree into the app.
Quick check
Which one has fewer vulnerabilities?
This post cannot answer that, and a raw count would mislead anyway. Look at how fast you can patch, how narrow your privileged surface is, and how well you review it.
