Show HN: Suparelay – Call any phone in the world from a browser tab

I'm travelling a lot, and often need to call numbers in my home country (a telco, a bank). Surprisingly, ever since Skype died, the apps that were meant to replace it launched once and never updated

So today, I'm presenting to you - Suparelay.

It works just like your phone... (revolutionary I know): - it remembers numbers you called - it looks like... a typical phone screen - it has a keypad that works during the call, for those "press 1 for your account" menus - it costs 90% less than using your local carrier for international calls

I compared 31 popular international calling destinations (in the Americas, Europe, Asia, Africa and Oceania) against 6 legacy carriers (T-Mobile US, AT&T Prepaid US, Vodafone UK, Airtel India, Claro Brazil and China Mobile), and to my surprise, the difference is insane.

Calls start from 2 cents a minute, you pay only when somebody answers, and there is no app to install: your browser is your phone.

Try it out and tell me what you think.

Say bye to vibe-coded Skype replacements, say hi to Suparelay!
