Kutt vs RedirHub

Kutt is a free, open-source, self-hostable URL shortener supporting custom domains, link expiration, password protection, and per-link statistics. The public instance and REST API live at kutt.to (authenticated with an X-API-Key header), and the AGPL-licensed codebase can be self-hosted for full control. Note that the old kutt.it domain is no longer operated by the project — its maintainers warn it may now be a phishing site — so integrations should target kutt.to.

RedirHub is a URL-redirect and link-management platform focused on bulk redirects, custom domains with automatic HTTPS, uptime monitoring, and click analytics. It exposes a REST API (Bearer API key) for programmatically creating and managing redirect rules and hosts, returning JSON. A free tier covers a limited number of redirects and one domain, with paid plans adding volume, more domains, and longer analytics retention.
