Live rates, zero setup.
Pick a source currency and a target currency, set the amount, and the widget shows the live converted value with the current mid-market rate underneath. 150+ currencies with flag markers.
Data is pulled from ExchangeRate-API, with an automatic fallback to Frankfurter if the primary source is unavailable. Results are cached in your browser for an hour, so the widget stays responsive even offline.
