CNAME verify
Bring your own domain
CNAME-based, per-account. We generate the records in the dashboard; once you add them at your DNS provider and propagation completes, your branded short links go live with auto-SSL via Let's Encrypt - no re-deploys on our side.
Print + offline
QR codes with their own analytics
Auto-generated for every link, with their own scan rollup so print and offline campaigns are measurable too. Download SVG/PNG/PDF, ship to your designer, ship to the printer.

404
Campaign ended. Visitor lands on a broken page.
attr.so
PAUSED
Visitor lands on your placeholder. Branded. Apologetic. Linkable.
No more 404s
Paused redirects, not broken links
When a campaign ends, send paused links to a friendly placeholder URL instead of a 404. Useful when the link is already out in the wild and you can't pull it back.

Cookie-free on the redirect.
When a visitor clicks an attr.so shortlink, the redirect sets no cookies, loads no third-party scripts, and does not fingerprint the browser. The click is measured server-side. EU data residency is on the roadmap for supported plans.
