Open source alternative to:

Flink is a free and open-source URL shortener designed for zero-configuration deployment. Built with ASP.NET Core, it offers a lightweight and fast solution for shortening URLs, generating QR codes, and optionally exposing OpenTelemetry metrics for monitoring.

Flink supports containerized deployment with Docker, Podman, and Kubernetes, making it easy to self-host in any environment. Its zero-config philosophy means you can get up and running quickly without complex setup procedures.

While smaller in community size compared to alternatives, Flink provides a clean REST API and modern .NET stack for developers who want a simple, self-hosted link shortening solution. It serves as an open-source alternative to commercial services like Bitly, TinyURL, Rebrandly, Short.io, and Cutt.ly.
