Rebrandly vs Shrtlnk

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.

Shrtlnk is a lightweight, developer-focused link shortener: register for an API key, then POST a URL with an api-key header to receive a short shrtlnk.dev link and basic click counts as JSON. It is built for simple programmatic shortening rather than a full marketing dashboard, and its free tier covers typical developer usage.
