What is your "Software As A Service"? Post and Spread Awareness

it would be great to know what you guys are doing in the SaaS:

[post your SaaS link]
Q1. Why you created it? [try to explain in less than 25 words]
Q2. What framework/stack you used?
Q3. What is your end goal with it? [except being rich]

This one is a bit realistic but it's equally important:
Q4. If it's not working out, what are gonna be your next steps, if you plan to continue?
