I built an international calling platform for the past 6 months▲38
I built Voklit because I was tired of paying $2+/min to call banks and airlines overseas. Needed a US number that works anywhere with actual affordable rates. It's a web-based VoIP service (mobile apps coming soon). You get a real US phone number, pay-as-you-go minutes on top of a small subscription that covers the infrastructure. Bootstrapped, solo founder. Built with [Go/Next.js/ and Websockets] if anyone's curious about the stack. Adding more countries soon. Happy to answer questions or hear feedback.
