ClearLink
A URL shortener built so visitors can see where a short link goes before following it, with tamper-evident sealed links.
Short links hide where they lead. That is exactly what makes them useful for phishing and bait-and-switch: a link can point somewhere harmless today and somewhere else tomorrow, and visitors have no way to check before clicking.
ClearLink is a URL shortener built around transparency. Every short link has a public information page showing the real destination, its safety status, whether and how often the destination has changed, and what access rules apply. Links can also be sealed — made permanently immutable, with a signed receipt anyone can verify to prove the destination has never changed.
It suits organisations and creators who share links publicly and want their audience to be able to trust them. It is a Bun monorepo with a Next.js dashboard, a Fastify API, a dedicated redirect service and a background worker, over PostgreSQL and Redis.
