Architecture

Built on Tauri for a lightweight desktop experience, delivering native performance with minimal overhead. The frontend utilizes clean HTML, CSS, and JavaScript to seamlessly handle real-time data API integrations without complex framework dependencies. The architecture strictly divides system-level operations from the user interface. Core system tray logic and OS integrations are handled entirely by a robust Rust backend, guaranteeing exceptionally low memory usage while running continuously in the background.

The Backstory

I’ve always found it annoying to open a browser just to check a quick exchange rate, especially when I’m in the middle of a project. I wanted something that was just a click away, sitting right in my system tray. CurrencyNode was born from that need for a fast, native-feeling tool that doesn't get in your way. It’s built to be simple, lightweight, and always available when you need to make a quick calculation without breaking your workflow.
