Open-source, self-hosted URL shortener with a full REST API — a free alternative to Bitly for link shortening and click tracking.

Why it is useful

Shlink provides short-link creation, custom slugs, and click analytics through a REST API and companion web client, letting developers build shortened-link infrastructure on their own domain instead of paying for Bitly's tiered plans. Useful for anyone who needs shortened links at volume without per-link costs.
