tr1.in

tr1.in is a link shortener where one short code can be three different things.

A redirect — the classic short link. No account required.

A link list — one code that opens a page listing several addresses; the visitor taps one or copies them all. This is what makes a printed QR code useful: the code on the poster never changes, but what sits behind it can.

A digital card — a personal page with your name, title, company, location, a short bio, a photo and the accounts people can find you on. One link instead of a bio full of usernames. Five themes.

Whatever kind it is, every link gets a QR code (PNG or SVG, any size, downloadable), click statistics broken down by browser, platform, language and — separately — which crawler fetched it, and a management page you can open without an account, using the link's own token.

Signing in is optional and adds bulk creation (up to 100 URLs from one paste), a list of everything you've made, and the card editor. Email and password, or Google, Microsoft or GitHub.

Shared links unfurl properly: preview crawlers are sent straight to the destination, so WhatsApp or X shows that site's own title and image, while people get an interstitial telling them where they're about to land and offering a report link.
