description: "A desktop application is the right answer when the work happens on the machine and not in a browser: files that never leave the office, a tool the team opens every morning, a window that keeps working when the connection does not. I build those in Rust with the interface in Tauri, so what you install is one small file."

# I Will build a Lightweight Cross-Platform Desktop App in Rust and Tauri for Windows, macOS and Linux

Built for small businesses and in-house teams that have outgrown a spreadsheet or a script and want a proper program with its own window. In Tauri, the heavy work, such as processing large files or searching thousands of records, runs in Rust, while the screens are plain web code, so a new screen later is a small job.

Starter is one application with up to 3 screens, built for the platform you name, with a running build early in the project and the source in your repository. Standard goes to 6 screens and adds builds for Windows, Linux and macOS, a local SQLite database with search, and CSV or Excel import and export. Advanced goes to 10 screens, includes all of that, and adds automatic updates, installers for each platform, and a release workflow that builds them on every tag you push.

Typical jobs: an internal tool that reads and writes files in a shared folder, or a viewer for data your team keeps in CSV or a database. If the brief grows mid-order, I quote the extra screen before doing it: the add-on, or a new order.

Design: a clean, standard interface by default, or your mockups and brand colors if you have them.

Not included: games, mobile apps, anything that has to live in a browser tab, copies of existing commercial software.

The code is yours: every tier includes the full source in your repository, and you can change it, reuse it or hand it to another developer. After delivery, I fix anything that doesn’t work as we agreed, free of charge.

I’ve been in IT for 10+ years and build in Rust. My public work includes reqwest-rotate, an open-source Rust HTTP library on crates.io, with a full test suite and CI.

Written updates each working day, fast replies, no calls.

Steps for completing your project
1. Scope confirmed in writing – I read your requirements and confirm the screen list, the data formats and the tier fit before any code. A screen is one window or view the user works in.
2. First screen as a running build – The app shell with the first screen working end to end on your real data, so you can run an early build and change direction while it is cheap.
3. Remaining screens, with tests – The rest of the screens, each with tests for the logic behind it. On a multi-day build you get a short written update every working day.
4. Builds, database, installers – Builds for the platforms your tier includes, the local database and import/export on Standard, automatic updates and installers on Advanced.
5. Handover in your repository – Source delivered in your repository with a written handover: how to build it, how to run the tests, how to ship an update.
