Lynx is a self-hosted open source URL shortener with a simple UI. The thing I like most about Lynx is its speed and simplicity in adding links. You can use it as alternative to Reduced, Shlink, and Slash. Convert those ugly and long URLs into short, easy to manage links. In this step by step guide I will show you how to install Lynx on your Synology NAS using Docker & Portainer.
