A link tool built for the people clicking it
Most link shorteners are one of two things: an enterprise sales funnel, or a tracker dressed up as a tool. Attr.so is the boring, useful version - a short URL that redirects fast, tells you where the click came from, and doesn't load a single ad-tech beacon on the way.
It's privacy-first by default: no cookie banner on the redirect, no third-party beacons, and click analytics measured server-side so they survive ad blockers. Every link runs on your own custom domain, so the brand - and the data - stays yours.
It was built by one developer who still uses it every day, which is exactly why there's no paywall around your own data.
Fast redirects on an honest data foundation
We led with the redirect: it has to be instant, because every millisecond sits between a click and the destination. On top of that we built click analytics that capture where a click came from - cookie-free and measured server-side - without following the visitor around the web.
Custom domains were a first-class feature, not an upsell, so every short link stays on the owner's brand. We paired Postgres for the link and account model with a column store for high-volume click events, keeping analytics fast as the numbers grow.
No ad-tech beacons. No cookie banner on the redirect. No paywall around your own data. Privacy-first isn't a tier - it's the default.
A link platform that respects the click
Attr.so is live and operational - a self-funded, privacy-first link shortener that redirects fast, reports clearly, and never sells out the people doing the clicking. It's the link tool its own maker reaches for daily.
The stack.
