Transparent international money transfer services for foreign workers

I am a foreign worker trying to manage my budget, and I hate the unpredictable exchange rates at my local bank. What tools or services provide the most transparent pricing for sending money abroad?

I send money home regularly and need to stick to a strict budget, but my bank's hidden fees and fluctuating rates are frustrating. Can you recommend some international transfer services that are upfront about their costs?

Are there any money transfer platforms that offer transparent exchange rates for foreign workers who need to send money abroad without the surprise fees from traditional banks?
