Overview

Sink is a simple, fast and secure link shortener with analytics that runs entirely on Cloudflare's serverless platform. It is aimed at individuals and small teams who want a self-hosted shortener, and it is licensed under AGPL-3.0. A sibling project, Slite, offers the same features as a local Node.js or Docker process.

The dashboard is built with Nuxt 4 and shadcn-vue, the Vue port of shadcn/ui, styled with Tailwind CSS. Links are stored in Cloudflare D1 with Workers KV as a read cache, and traffic is recorded in the Workers Analytics Engine. A public demo is available at sink.cool with the site token SinkCool, and the project has browser, Raycast, Apple Shortcuts and iOS companions.
