Overview

Depo Tool

An open-source Steam library manager built with Tauri.

Depo Tool is designed to provide a transparent, automated, and structured way to integrate supported game packages into the Steam environment — without telemetry, tracking, or hidden processes.

Why I Built This

Many existing tools in this space lack transparency or modern architecture.
Depo Tool focuses on:

  • Open source codebase
  • Clean and modern UI
  • Secure and auditable logic
  • Performance-focused architecture

This project prioritizes clarity and control.

Core Features

  • Built with Tauri (Rust backend)
  • Modern desktop UI
  • Steam App ID search support
  • Automated manifest handling
  • Automated Lua file placement
  • Structured Steam folder integration
  • Dual CDN infrastructure (Cloudflare + GitHub)
  • Auto update system
  • No telemetry or data collection

How It Works

  1. Search for a supported title using its Steam App ID
  2. Download required package components
  3. Automatically extract necessary files
  4. Integrate them into the correct Steam directory structure

The entire workflow is automated to reduce manual steps.

Technical Overview

  • Framework: Tauri
  • Backend: Rust
  • Distribution: GitHub Releases
  • CDN: Cloudflare + GitHub

Goals

  • Maintain full transparency
  • Keep the project fully open source
  • Improve performance and stability
  • Expand platform support in the future

The Challenge

Challenges

Building Depo Tool came with several technical and architectural challenges:

1. Secure File Handling

Managing manifest and Lua file placement required careful handling to avoid incorrect Steam directory modifications. Ensuring safe automation without breaking user setups was critical.

2. Tauri + Rust Integration

Connecting a modern React + TypeScript frontend with a Rust backend inside Tauri required structured communication and state management between layers.

3. Steam Directory Structure

Steam’s folder structure and manifest behavior required detailed testing to ensure files were placed correctly and recognized properly.

4. Download Reliability

Implementing dual CDN infrastructure (Cloudflare + GitHub) required fallback handling and proper error management for stability.

5. Auto Update System

Ensuring smooth updates without breaking user configurations required additional planning and testing.

These challenges helped shape the architecture of Depo Tool into a more structured, modular, and performance-focused application.

The Solution

Solution

To address the architectural and security challenges, Depo Tool was designed with a structured and modular approach.

1. Controlled File Automation

Instead of manually modifying Steam configurations, the tool programmatically handles manifest and Lua placement using validated paths and controlled write operations. This reduces human error and improves reliability.

2. Clear Frontend–Backend Separation

The application uses Tauri to bridge a React + TypeScript frontend with a Rust backend.

  • The frontend handles UI and user interactions
  • The Rust backend handles system-level operations and file management

This separation keeps the system clean, secure, and maintainable.

3. Directory Validation System

Before writing any files, the tool validates directory structures and ensures the correct Steam paths are targeted. This prevents misplacement and unintended overwrites.

4. Redundant Download Infrastructure

A dual CDN strategy (Cloudflare + GitHub) ensures higher reliability and fallback support in case of network issues.

5. Structured Update Handling

The auto-update system is designed to preserve user configuration while safely deploying new versions.

By focusing on modular architecture, strict path validation, and automation safety, Depo Tool maintains transparency while delivering a streamlined user experience.

The Outcome

Outcome

The initial release of Depo Tool successfully established a stable and transparent foundation for the project.

Key Results

  • Functional desktop application built with Tauri and Rust
  • Streamlined automation of manifest and Lua handling
  • Structured Steam directory integration
  • Reliable dual CDN download system
  • Clean and responsive user interface
  • Fully open-source and publicly auditable codebase

Impact

The project demonstrates how modern desktop tooling can be built using web technologies combined with a systems-level backend. It provides a structured and automation-focused approach while maintaining transparency and performance.

Depo Tool now serves as a solid base for future enhancements, performance optimization, and expanded platform support.
