Tauri Desktop App Development
We build Tauri 2 apps with a Rust core and the operating system's own WebView: custom plugins, sidecar binaries, a least-privilege permission model, native integration and signed installers for Windows, macOS and Linux.
- 11+ years of experience
- 300+ projects delivered

Overview
What it is and when it fits
Tauri pairs a Rust core with a web interface. Instead of shipping its own browser, it renders your UI with the WebView that the operating system already provides, which is why Tauri apps tend to be smaller than Electron apps.
That choice brings a trade-off: the WebView differs between Windows, macOS and Linux, so rendering and feature support can differ too. We design for that from the start and test the risky parts early.
Who this is for
- Teams that want a desktop app with a web interface and a smaller footprint than a bundled browser.
- Products where native performance or memory-safe system code matters.
- Teams exploring desktop and mobile from one codebase with Tauri 2.
- Teams considering a move off Electron who want the trade-offs assessed first.

What we offer
What's included
Custom Tauri plugins
Rust plugins built on the Tauri plugin system for features the official plugin set doesn't cover, exposed to the frontend as typed commands.
Sidecar binaries
An external executable bundled as a Tauri sidecar so the app can run a separate process, such as a local server or CLI tool, alongside the Rust core.
Event and state bridging
Tauri's event system and shared state wired between the Rust core and the frontend, so both sides stay in sync without polling.
Bundle and installer configuration
Tauri's bundler configured for MSI and NSIS on Windows, a DMG on macOS, and AppImage, Debian or RPM packages on Linux.
Multi-platform CI builds
Build pipelines that produce Windows, macOS and Linux builds from one Tauri project and one CI configuration.
Electron to Tauri migration
An assessment of your Node.js dependencies and WebView risks, then a staged move of native code into a small Rust core.
Deliverables
What you get
- 01
Working Tauri app
A production build for the platforms you choose, with the Rust and web sources in your repository.
- 02
Rust commands with a minimal permission set
Each native capability the UI needs is exposed as an explicit command, and the app grants only the capabilities it uses.
- 03
Cross-WebView test results
Checks of your interface on WebView2, WKWebView and WebKitGTK, with notes on any differences we found and how we handled them.
- 04
Signed installers
Installers signed for each platform, and notarized on macOS.
- 05
Updater setup
Configuration of the Tauri updater plugin, which verifies update signatures, plus the release flow that produces them.
- 06
Handover documentation
Notes on the Rust and web split, how to add commands and how to release, so your team can continue.
Compare
The WebView on each platform
Tauri does not bundle a browser engine, so the engine you get depends on where the app runs.
| Platform | WebView | What to plan for |
|---|---|---|
| Windows | Microsoft Edge WebView2 (Chromium-based) | Windows 11 includes the WebView2 runtime. For machines without it, the installer can download or bundle it. |
| macOS | WKWebView (WebKit) | WebKit updates arrive with macOS and Safari updates, so users on older macOS versions may lack newer web features. |
| Linux | WebKitGTK | The version depends on the distribution, so test on the distributions your users run. |
| Android | Android System WebView (Tauri 2) | Test on physical devices and on the Android versions you support. |
| iOS | WKWebView (Tauri 2) | Expect App Store review and Apple signing requirements. |
Why it matters
What this gives you
A smaller download
An Electron installer carries its own copy of Chromium, usually tens of megabytes. Tauri uses the WebView already on the system, so a Tauri installer can be a few megabytes.
Memory-safe system code
The Rust core is memory-safe by default, which removes a class of bugs common in native C or C++ code.
Least privilege by default
The frontend can only call the Rust commands explicitly exposed to it, and only within the capabilities granted, so a compromised web view has limited reach.
A possible path to mobile
Tauri 2 can also build Android and iOS apps from the same Rust core and frontend. Mobile support is newer than desktop, so we check that the plugins you need work there first.
Our approach
How we build a Tauri app
Fit check
We review your UI, the features you need from the OS and the browsers your users have, then decide whether Tauri is a sound choice.
You get: A written fit assessment
Risk spike
We prototype the riskiest parts first, such as a complex UI feature or a native integration, on all target platforms.
You get: A working prototype and a go or no-go recommendation
Core and commands
We build the Rust core, define commands and set capabilities so the UI can reach only what it needs.
You get: A typed command layer with a permission map
Interface and platform testing
We connect the web UI and test it on each platform WebView, fixing differences as they appear.
You get: Tested builds for each target platform
Packaging and updates
We configure signing, installers and the updater plugin, then document the release process.
You get: Signed installers and a release runbook
When this is not the right fit
- Your interface must look the same on every operating system or needs a specific Chromium feature. Electron is the safer choice.
- Your team has no capacity to maintain any Rust, even a small core. Electron may suit you better.
- You must support operating system versions with old WebViews and cannot require users to update.

Common questions
Tauri 2 has been a stable release since October 2024 and is used in production apps. Whether it fits you depends on your team and requirements, so we test the risky parts first before committing to it.
Some, yes. The core and native features are written in Rust, but much of the application logic can stay in the web frontend. We keep the Rust layer small and documented so that it stays maintainable.
Tauri has an updater plugin that downloads new builds and verifies their signatures before installing. You host the update files, and we set up the pipeline that produces and signs them.
We can, if it fits. First we check which Node.js features the app relies on and how the UI behaves in the system WebViews. Some code moves over unchanged, and the Node-specific parts are rewritten in Rust or moved into the frontend.
Tauri 2 also targets Android and iOS, using Android System WebView and iOS WKWebView. Mobile is a newer part of the framework than desktop, so we check that the plugins and features you need are available before planning on it.
