frwrd.ing is powered by samestrin/url-shortening-api-vercel, a serverless application that provides URL shortening functionalities.

Using Vercel infrastructure - Vercel Functions, Vercel KV (Redis), and Vercel Postgres, this application offers a high performance, efficient and scalable solution for creating, serving, and tracking short URLs that redirect to the original, longer URLs.

If you'd like to host your own URL shortening service, then follow installation directions found in the README.md file.
