Desktop apps came back in 2026. Local-first software, AI applications that need to run on the user's machine, and the renewed taste for non-browser experiences brought desktop development back into focus. The question is which shell to ship in.
This guide picks one for each common shape of desktop app.
What changed in 2026
The three frameworks that matter all shipped major versions.
- Tauri 2 is GA. Mobile targets, plugin system stable, IPC redesigned.
- Electron continues to dominate enterprise. Slack, VS Code, Discord, Notion — they are not switching.
- Wails 3 ships a unified webview API. Cleaner Go-to-frontend bridge, native menus, better tooling.
How we picked
Five factors.
- Binary size and memory footprint
- Cold start speed
- Native API access
- Auto-update and code signing tooling
- Frontend framework choice
1. Tauri 2 — best modern default
Tauri uses the system webview (WebKit on macOS, WebView2 on Windows, WebKitGTK on Linux) instead of bundling Chromium. The result is a 5–15 MB installer instead of 80–150 MB. The backend is Rust, the frontend is whatever JS framework you like, and the IPC is type-safe with the right setup.
The trade-off: testing across three different webview engines means subtle CSS or JS bugs that Electron would not have. Plan for it.
2. Electron — best for compatibility and ecosystem
If you need a specific native module (a long list — see Slack's open-source ones), Electron has it. If you need a feature that landed in Chrome last week, Electron has it next month. If you need to hire someone who knows the framework, the pool is huge.
The catch: every Electron app ships its own Chromium. That is the price for the consistency and the ecosystem.
3. Wails 3 — best for Go-native teams
Wails is the Go equivalent of Tauri. Single binary, native webview, Go backend, JS frontend. If your team writes Go and you do not want to add Rust to the stack, this is the obvious pick. The ecosystem is smaller than Tauri's but the active community is solid.

Common mistakes to avoid
Skipping code signing. macOS will block unsigned apps with no easy override. Windows will throw SmartScreen warnings. Pay for the certificates.
Ignoring auto-update on day one. Updaters are hard to retrofit. Pick Tauri's updater, electron-updater, or Sparkle and integrate it before the first release.
Bundling native dependencies you do not need. Each native module slows startup, increases bundle size, and creates a cross-platform debugging surface.
FAQ
Can I reuse my web app's code?
Mostly yes. The frontend layer is HTML/CSS/JS in all three. Server-side or backend logic needs porting to Rust, Go, or Node depending on the framework.
What about Flutter Desktop?
Flutter does desktop too, with the same UI consistency benefits. Smaller community for desktop specifically. Worth considering if you want one framework for mobile and desktop.
How do I distribute outside the app stores?
Direct downloads work. Use a CDN, sign the binaries, and ship a self-updating installer. Auto-update is the part most teams underestimate.
