Dev Core Tools

Dev Core Tools is a local-first desktop app that brings everyday developer utilities into one fast, offline workspace. It combines an Angular 21 interface with a Tauri v2 shell and Rust commands for native capabilities such as image processing, hashing, and file access.

The app is designed for common "paste, inspect, convert, generate" tasks without sending data to a remote service.

Provenance: This project was built with extensive assistance from AI agents. Every feature and capability has been thoroughly tested to ensure a high-quality, reliable experience.

Highlights

• 45+ tools for formatting, encoding, crypto, images, networking, data conversion, and generated test data.
• Local-first workflow for sensitive snippets, tokens, images, and configuration files.
• Native desktop packaging through Tauri for Windows, macOS, and Linux.
• Angular standalone components, lazy-loaded tool routes, and Tailwind-based styling.
• Command palette, pinned tools, first-run experience, and light/dark/system themes.

Installation

Pre-built installers are available on the GitHub Releases page. Download the package for your platform and follow the steps below — no build toolchain required.

Windows

File	Type	Notes
*.msi	MSI installer	Recommended — supports auto-updates

Linux

File	Distro family	Notes
*.deb	Debian / Ubuntu	Install with sudo dpkg -i *.deb
*.rpm	Fedora / RHEL / openSUSE	Install with sudo rpm -i *.rpm
*.AppImage	Any	Mark executable and run directly

Debian / Ubuntu:

sudo dpkg -i dev-core-tools_*.deb

Fedora / RHEL:

sudo rpm -i dev-core-tools_*.rpm

AppImage (any distro):

chmod +x dev-core-tools_*.AppImage
./dev-core-tools_*.AppImage

Quick Start

Prerequisites:

• Node.js 20.19+, 22.12+, or 24+
• Rust 1.77.2 or newer
• Tauri v2 system dependencies for your platform
• Tauri CLI v2 through Cargo or npm

npm install
npm run tauri:dev

The Angular dev server runs on http://localhost:4200, and Tauri opens the desktop window against that dev server.

For a browser-only development loop:

npm start

For production desktop bundles:

npm run tauri:build

Build outputs are written under src-tauri/target/release/bundle/.

Common Scripts

Command	Purpose
npm start	Run the Angular dev server on port 4200
npm run build	Build the Angular frontend
npm test	Run Angular unit tests with Karma/Jasmine
npm run tauri:dev	Run Angular and the Tauri desktop shell in development
npm run tauri:build	Build production desktop bundles
