About Sink

Sink is an open-source link shortener designed to run on Cloudflare's serverless platform rather than a traditional server. You deploy it to Cloudflare Workers from the GitHub repository; links live in Cloudflare D1 with Workers KV as a cache, and Workers Analytics Engine handles click statistics, so redirects are served from Cloudflare's global edge network with no server to manage. It includes a web dashboard for creating and managing links, custom slugs, passwords and expiry, QR codes, optional AI-generated slugs via Workers AI, near-real-time analytics, plus an API and an MCP endpoint. The code is licensed under AGPL-3.0. It suits developers already using Cloudflare who want a free shortener on their own domain without managing servers. It is a community project, so there is no hosted version or support, and it is tied to Cloudflare's platform, which some will see as a lock-in risk.

Best for: Developers on Cloudflare who want a free, serverless shortener on their own domain.
