WhatsLink

Turn any phone number into an instant WhatsApp chat link — message anyone without ever saving them to your contacts.

WhatsApp won’t let you message a number you haven’t saved. WhatsLink fixes that: type or paste any phone number and it builds an instant wa.me chat link — so you can reach a marketplace seller, an Airbnb host, a delivery driver, or a number off a flyer without adding a single new contact.

What it does

Privacy first

No account, no sign-in, and nothing collected about your contacts. The numbers you save live only on your device — nothing is uploaded anywhere.

WhatsLink is an independent project and isn’t affiliated with WhatsApp or Meta. It opens chats through WhatsApp’s standard wa.me links (WhatsApp must be installed).
