Free Url Shortener vs Rebrandly

Ulvis' Free URL Shortener shortens links through a plain GET or POST API with no signup or key required. It supports custom short names, click limits, passwords, and expiry dates, returning results as JSON or XML. It sends no CORS header, so the API must be called from a server rather than directly from browser JavaScript.

Rebrandly specializes in branded short links on your own custom domain, aimed at marketing and brand-consistent link sharing. Its REST API uses an apikey header and covers link creation, custom slashtags, tags, domains, and click analytics, returning JSON. A free tier allows a capped number of branded links per month, with paid Starter, Pro, and Enterprise plans scaling link volume, domains, and team features.
