It means Let's Shorten That Url.

Or you can see usage with Docker.
By default, there are 8 361 453 672 available combinations.
I think the sqlite db will explode before you reach this limit, but you can use PostgreSQL or MySQL as database instead of SQLite.
If you want more shortened URLs than that, open lstu.conf and change the length setting.
Every time somebody uses Lstu, it will create 'waiting' shortened URLs codes in order to be quick to shorten the URLs.
Accordingly to the lstu.conf configuration file, it will create provisioning waiting URLs, adding them provis_step by provis_step.
You can see it working and use it at https://lstu.fr.
See https://lstu.fr/api. Your instance will provide the same page with your URL.

Lstu is written in Perl with the Mojolicious framework and uses Milligram CSS framework to look not too ugly.
See the AUTHORS.md file.
An ansible role and a terraform plan reside under the .provision directory. An user could utilize the terraform plan if they chose to deploy lstu on AWS, if that's not the goal, they could simply execute the ansible role in part. Usage docs for both are present in their respective directories.
