Every few months someone declares Electron dead, points at Tauri's tiny bundles, and moves on. The truth is more useful than the headline. Both frameworks are shipping real software at scale in 2026, and the right choice comes down to one tradeoff that most hot takes skip past.
Here's the short version. For a new desktop app, start with Tauri. The bundle size, memory, security, and mobile wins are real and measurable. Reach for Electron when your UI must render identically everywhere, when you lean hard on the Node ecosystem, or when your team is JavaScript-only with no room to touch Rust. And if you already have a working Electron app, the honest answer is usually to stay put, because migrating is closer to a rewrite than a refactor.
Let me break down why, with real numbers.
Quick verdict
| Tool | Best for | Bundle size | Idle memory | Rating |
|---|---|---|---|---|
| Tauri | New, lean apps and mobile reach | 2 to 10 MB | ~30 to 50 MB | 4.5/5 |
| Electron | Complex, render-heavy apps | 80 to 200 MB | ~120 to 400 MB | 4/5 |
Tauri: the lightweight modern default
Tauri flipped the desktop model. Instead of shipping a whole browser with your app, it uses the WebView the operating system already has (WebView2 on Windows, WKWebView on macOS, WebKitGTK on Linux) and runs your backend logic in Rust. Version 2, stable since late 2024 and now on the 2.11 line, is the release that turned Tauri from a promising challenger into a real platform decision. Momentum backs that up: Tauri's GitHub repositories have grown around 55% year over year while Electron's growth has plateaued, and a 2025 Stack Overflow survey found 72% of desktop developers had considered switching frameworks in the past year, mostly over performance and bundle size.
The numbers are the headline, and the gap is enormous. Tauri apps typically ship at 2 to 10 MB, against Electron's 80 to 200 MB. Idle memory sits around 30 to 50 MB, roughly 50 to 75% lower than Electron. Startup is consistently under half a second, where Electron takes one to two. On a cheap laptop running six apps at once, that's the difference between a machine that breathes and one that swaps to disk.
The other big shift in v2 is mobile. Tauri now targets iOS and Android from the same codebase, which Electron cannot do at all. Security is also better by default: Tauri uses a capability-based permission system where everything starts disabled and you opt into what you need, rather than Electron's model where you harden the renderer yourself. You keep your web frontend too, React, Vue, Svelte, or vanilla, so the UI code barely changes.
The honest cons: initial builds are slower because of Rust compilation, adding maybe 20 to 25 seconds to a cold build. Because it uses each platform's native WebView, rendering can differ slightly across operating systems, and WebKitGTK on Linux has known performance quirks on some distributions. Deep native work means writing Rust, and the ecosystem, while growing fast, is thinner than Electron's. The auto-updater downloads a full binary rather than a diff, though for a 5 MB app that hardly matters.
Who should not use Tauri: teams that need pixel-identical rendering on every platform, anyone with zero capacity to touch Rust for native features, or apps that depend on a specific Node-only library with no Rust equivalent.
Electron: the mature, proven heavyweight
Electron is the established standard, and it earned that position. It bundles Chromium and Node.js with every app, which is exactly why it's heavy and exactly why it's reliable. Every user runs the same browser engine regardless of their OS, so your UI renders identically everywhere. For a rendering-heavy app where consistency is non-negotiable, that's a genuine advantage, not just bloat. The 2026 releases (Electron 34.x, on Chromium 132 and Node 22) trimmed baseline memory a little, but the core architecture is unchanged.
The ecosystem is the real moat. Electron has a mature, battle-tested toolchain: electron-updater handles differential updates, staged rollouts, and code signing, including the macOS notarization and Windows signing that are mandatory for user trust in 2026. There's a documented solution for nearly every edge case, and the talent pool is deep because it's all JavaScript. VS Code, Slack, Discord, Figma, and 1Password all run on it. That's not an accident, it's what happens when a complex product needs proven distribution. Since the main process runs on Node, your whole team can work across frontend and backend without learning a second language. If you want to understand that runtime layer better, I covered it in Bun vs Node vs Deno.
The honest cons: the weight is real and structural. That bundled Chromium adds 80 to 120 MB before your own code, and each window you open spawns its own renderer process, effectively a mini-Chromium with the memory bill to match. Idle memory routinely lands in the hundreds of megabytes. Security is opt-in rather than default, so you have to correctly configure context isolation, disable Node integration in renderers, use preload scripts, and set a content security policy. Get that wrong and you've shipped a vulnerability.
Who should not use Electron: teams building lean utilities or menu-bar tools where install size and memory are product requirements, anyone who needs mobile from the same codebase, or security-sensitive apps that benefit from a smaller attack surface.
How do they compare head to head?
Five dimensions decide it.
Size and memory. Tauri wins decisively. Bundles are roughly 10 to 25x smaller and memory runs 50 to 75% lower. For consumer apps, utilities, and anything users keep open all day, that's a real user-experience win, smaller downloads, cooler laptops, longer battery life.
Rendering consistency. Electron wins. Because it ships its own Chromium, your app looks identical on every platform. Tauri uses each OS's native WebView, so CSS and fonts can render slightly differently, and you'll spend more time testing across platforms.
Ecosystem and distribution. Electron wins. The auto-update, signing, and packaging story is more mature, and there's a library or Stack Overflow answer for almost everything. Tauri's tooling is good and improving, but you'll hit more rough edges.
Language and team fit. Depends on your team. Electron is JavaScript end to end, so any web dev can own the whole stack. Tauri keeps the frontend in JavaScript but puts native logic in Rust, which is a real onboarding cost if nobody knows it.
Mobile reach. Tauri wins by default, because Electron doesn't compete here at all. If one codebase across desktop and mobile matters to you, the decision is basically made.
Build speed. Electron wins this one. Its JavaScript toolchain compiles fast, often packaging in around 15 seconds, while Tauri's Rust step adds roughly 20 to 25 seconds to a cold build. Later builds are quicker thanks to caching, but in a rapid edit-and-rebuild cycle that initial compile is a real, if minor, tax on your day.
Here's the decision in one view:
Final recommendation
For a new desktop app in 2026, start with Tauri. It produces dramatically smaller, lighter, faster apps, ships with better security defaults, and reaches mobile from the same codebase. For most indie hacker projects, developer utilities, menu-bar tools, local-first apps, lightweight editors, that profile fits perfectly, and the Rust requirement stays small because most of your code lives in the frontend.
Choose Electron when your app is genuinely complex and render-heavy, when identical cross-platform rendering is a hard requirement, when you depend on its mature update and signing pipeline, or when your team is JavaScript-only and Rust is off the table. It's the safer pick for a large web-heavy product, and it is absolutely not obsolete.
And if you already ship an Electron app that works and nobody is complaining about its size, leave it alone. The migration cost almost never beats the pain it removes. Pick based on what your users actually feel, not on a benchmark chart.
