About
Short links. Serious control.
4u.fyi is a URL shortening platform built for people who treat links as infrastructure: marketers, publishers, developers, and teams who share links professionally.
The idea is simple — a short link should be simple. What happens behind it, however, deserves real tooling: custom aliases, click analytics, QR codes, expiration, click limits, and a dashboard to manage everything from one place.
4u.fyi runs on a lean stack — PHP, MariaDB, and hand-written front-end code — with redirects served from a lightweight path so your audience lands fast.
We do not sell click data, and we do not show third-party advertising on the platform.
