#What is Sink?

Sink is a lightweight, open-source URL shortener built exclusively for developers, marketers, and teams who need quick, reliable link management with actionable insights, without the bloat of enterprise tools or hosting headaches. Its core value is delivering a minimalist yet powerful platform that shortens URLs, monitors performance, and adds smart customizations—all running serverlessly on Cloudflare for global edge delivery and ironclad security. Powered by Cloudflare Workers, Pages, and KV storage with Hono for routing, it's ideal for use-cases like campaign tracking in email blasts, social media bio links, API endpoint proxies, or A/B testing redirects—anywhere you want analytics-driven shortening without setup friction or ongoing bills.

#Features ⚡

• URL Shortening: Instantly compress any long URL into a clean, shareable sink.cool/[slug] format, with automatic redirection and optional password protection for added security.

• Built-in Analytics: Real-time dashboards showing click counts, geographic data, device types, and referrers—exportable for deeper analysis without third-party trackers.

• Custom Slugs: Craft personalized, case-sensitive short codes for branding, or let AI suggest creative ones based on your link's context for effortless memorability.

• Link Expiration: Set auto-delete timers on links for time-sensitive promotions, compliance needs, or ephemeral shares, with notifications on expiry.

• Serverless Architecture: Zero-maintenance deployment using Cloudflare's edge network—handles spikes in traffic seamlessly without provisioning servers.

• QR Code Generation: One-click creation of scannable QR codes tied to your short links, perfect for print materials or offline-to-online funnels.

#Pros ✅

• Blazing-fast global performance via Cloudflare edge, with sub-50ms response times even under load

• Completely free to deploy and use, eliminating hidden costs for indie projects or high-volume campaigns

• Simple codebase makes it easy to fork, extend, or self-host for custom needs

• Strong privacy focus with no user tracking beyond your analytics, aligning with GDPR vibes

• Quick value—deploy and start shortening in under 5 minutes, analytics kick in immediately

#Cons ⚠️

• Limited to basic analytics; lacks advanced segmentation or A/B testing without custom extensions

• Relies on Cloudflare ecosystem, so migrating to other providers requires code tweaks

• No built-in team collaboration features like shared dashboards—best for solo or small-team use initially
