One WhatsApp link is the invitation. Guests tap Yes, Maybe or No and say how many are coming, open the venue in Maps, and pick a gift nobody else will bring. No app for guests, two minutes for the parent. Built in Bengaluru, free during early access.

Hi Product Hunt, Balakrishna here. My kid's last birthday was forty WhatsApp messages of "so who's coming?" and three identical Lego sets. invi8 is the fix a parent in India actually needs: the invitation is a WhatsApp link, RSVPs carry head counts (adults and children, because return gifts), the venue has a Maps button, and the wishlist marks a gift as taken without saying who took it. Guests install nothing; grandparents manage. What we deliberately did not build: no child's date of birth is shown publicly, guest phone numbers are never exposed to other guests, no trackers, no ads. Free while we learn from real Bengaluru parties. Tell me what breaks. Live demo you can tap through like a guest: https://invi8.in/e/demo-aryan-12...

For anyone who would rather watch than read, we just published a two minute walkthrough of the whole flow: a parent making the invitation, the WhatsApp link going out, guests replying, and the wishlist stopping the third identical Lego set.

The part I would most like feedback on is the RSVP screen. An Indian birthday usually means a whole family turning up, so guests enter adults and children separately instead of a single yes. I would love to know whether that reads clearly to people outside India as well.
