About

I’m an independent developer from Japan. I like building simple tools that solve small problems in everyday life. I built knocks because sometimes you want to share text or photos with someone without exchanging contact details. No account. No app. Just create a space and share.

knocks - Share without exchanging contact details.

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.
