Sink is a self-hosted link management platform that combines URL shortening with click analytics and geographic tracking. It provides a deployable system for creating, editing, and organizing short links, with built-in tools for measuring engagement through real-time click event collection and visitor location data.
The platform distinguishes itself through AI-powered slug generation that produces human-readable short link identifiers by analyzing target page content, replacing random string generation. It supports geo-aware request routing that redirects visitors to different destinations based on their country or region, along with device-based routing and password-protected link gates that intercept requests with a challenge page before allowing redirects. Duplicate URL detection scans batches of target URLs against existing records to prevent creating multiple short links for the same destination.
Additional capabilities include bulk JSON import and export for migrating link records, on-demand QR code generation that caches results for repeated requests, and configurable link access controls with expiration dates and warning pages. The platform stores short link metadata and analytics in a local SQLite database for zero-configuration persistence.
