The Tauri vs Electron debate usually happens between people who haven’t shipped anything with either. I’ve shipped seven tools with Tauri and maintained Electron apps in a previous role. Here’s what actually matters.
Tauri is a desktop app framework with a Rust backend and a web frontend. The frontend runs in the system webview (WebView2 on Windows). Your frontend is regular HTML/CSS/JS — React, Svelte, whatever. The Rust backend exposes functions that the frontend calls via invoke().
Electron ships its own Chromium and Node.js. That’s why Electron apps are 150+ MB and Tauri apps aren’t.
QuickProbe is a server fleet monitor. The backend connects to Windows machines via WinRM and Linux via SSH, does Active Directory discovery with ldap3, stores credentials in Windows Credential Manager via DPAPI, and probes servers every 120 seconds. About a dozen Tauri commands cover probing, credential management, AD queries, RDP launching, and service control.
This is where the Rust/web split works well. The frontend (React 19, Tailwind, DaisyUI) handles display. The backend handles everything requiring native Windows API access — credential storage, WinRM sessions, LDAP queries. The language boundary enforces the separation. Electron would need native addons for the Credential Manager bits; in Tauri the windows crate gives you direct API access with compile-time type checking.
BitBurn is a file wiping tool. Backend handles the erasure algorithms and streams progress events to the frontend. Total app size: 466 KB. An Electron equivalent starts at around 150 MB.
The progress streaming pattern is worth knowing: long-running operations in Tauri emit events rather than blocking the command. The wipe starts async, the frontend receives progress events, a separate command handles cancellation. It’s clean once you understand the model.
Tauri’s WebView2 on Windows is Chromium-based, so you’re fine there. On macOS and Linux you’re on WebKit, and subtle rendering differences surface if you’re using JS libraries built for Chromium (Monaco Editor being the obvious one). For Windows-only tools it doesn’t matter.
Electron’s advantage is guaranteed Chromium everywhere, and Node.js already available if you need to shell out to npm tooling. If your team has no Rust experience, Electron is also just faster to start with.
For tools that don’t need a webview at all — simple, focused utilities — egui compiles the UI directly into the executable. LockSmith is 4 MB and starts in 0.5 seconds. That’s not achievable with any webview-based framework.
My tools use Tauri where UI complexity needs web tooling and native system access in the same app. They use egui where start time and binary size matter more than UI sophistication. The choice depends on what the tool actually needs to do.
