CleanURI vs Cutt.ly

CleanURI is a minimal, free URL shortener with a single documented endpoint: POST /api/v1/shorten takes a (URL-encoded) long URL and returns a short cleanuri.com link as JSON. It needs no account or API key, making it one of the simplest shorteners to call programmatically, though it offers no analytics, custom aliases, or link management beyond creation.

Cutt.ly shortens links to cutt.ly URLs and layers on click tracking, custom back-halves, branded domains, and campaign management. Its REST API is called with an API key issued from a Cutt.ly account and returns JSON; the same key drives link creation, editing, and per-link statistics. A free plan covers basic shortening and stats, with paid tiers adding branded domains, team seats, and higher limits.
