Sink is a serverless link shortener built to run entirely on Cloudflare's edge infrastructure, delivering speed, security, and zero server management. Designed for developers and teams who need reliable URL shortening without infrastructure overhead, Sink combines essential link management features with real-time analytics.
Core Capabilities
The platform offers URL compression with customizable slugs (including case-sensitive options), AI-powered slug generation, and configurable link expiration. Analytics are powered by Cloudflare Workers Analytics Engine, providing insights into link performance without third-party tracking dependencies.

The project includes a browser extension (Sink Tool), Raycast extension, Apple Shortcuts integration, and an iOS app for cross-platform access. Deployment targets Cloudflare Workers or Pages, with API access and OpenAPI documentation for programmatic integration. Released under AGPL-3.0, the project welcomes contributions for enhanced link management, analytics improvements, and performance optimization.

Frequently asked questions
Does Sink require a Cloudflare account?
Yes, Sink runs entirely on Cloudflare infrastructure. You'll need a Cloudflare account to deploy to Workers or Pages, and access to Workers KV and Analytics Engine.
Can I use my own custom domain?
Yes, Sink supports custom domains through Cloudflare's domain management. Configure your domain in the deployment settings to use branded short links.
How does the AI slug generation work?
The AI slug feature generates contextual short URLs based on the destination page content or metadata, creating more memorable and descriptive slugs automatically.
Is there a limit to how many links I can create?
Limits depend on your Cloudflare Workers KV plan. The free tier supports substantial usage, while paid plans offer higher quotas for storage and requests.
Can I export analytics data?
Analytics are stored in Cloudflare Workers Analytics Engine. You can access data through the dashboard or API; export capabilities depend on your implementation and Cloudflare plan features.
