Sometimes you want to share a photo, a file, or some text with someone — but you don't want to exchange contact details. knocks lets you share without exchanging email addresses, phone numbers, or social accounts. Create a temporary space, show the QR code, and start sharing. No account. No app. No contact exchange. Just create a space and share.
Hi Product Hunt! 👋
I'm an independent developer from Japan, and this is my first time launching knocks on Product Hunt.
I built knocks around a simple idea: sometimes you want to share something with someone nearby, but exchanging contact details feels like too much.
A photo after meeting someone, a file at an event, or something you need to send to a stranger — there are lots of small moments like that.
I'd love to hear how you would use knocks, or what kind of situation made you wish you had something like this.
