Flask URL-Shortener

Live Demo (on a not-so-short URL)

Features

Shortens URLs to a default 3-digit prefix using a random character and letter combination.
Checks if the shortened URL already exists and attempt to re-run the code-generator until it finds an available combination.
All data is stored in a single MySQL table.
Case-sensitive. The database distinguishes between upper- and lower-case characters.
A Stats page lists all the shortened URLs, and shows how many times a target link has been redirected.
There is a button to automatically copy the shortened URL to clipboard.
Has an option to use Recaptcha to prevent spambots.

Setup

Lastly, alter the MySQL table to allow case-sensitive characters:
