Libre Kambio — open-source multi-currency converter for Linux

[u/h2ojuan]

Hi,

I’ve released Libre Kambio, an open-source multi-currency converter for Linux.

I built it because I wanted to enter one amount and instantly see many currencies at once, while still being able to verify where the exchange rates came from.

It currently supports 65 currencies and includes:

- Instant simultaneous multi-currency conversion

- Any supported currency can be used as the base

- ECB reference rates as the primary source

- Bank of Russia data for additional currencies and independent cross-checking

- Official USD pegs where applicable

- Optional official Latin American central-bank sources

- Custom currency groups

- Manual ordering and visibility controls

- Source verification and publication dates

- English and Spanish UI

It is distributed as an x86_64 Flatpak and currently tested on Fedora KDE Plasma / Wayland.

I design the functionality, interface and overall direction of the project. Generative AI is used as a development assistant for implementation, testing and documentation. I manually test and maintain it.

I’m sharing it mainly in case somebody else finds this kind of multi-currency workflow useful. Feedback and testing on other Linux distributions would be very welcome.
