Just so you know, the tool is great, the code looks fine and the link is appreciated. I think the reason why you get down voted is because your comment could be read as you humble bragging.

Don't take it personally though, I've done similar posts/comments in the past and it took me quite some time to realize comments with this tone can be discouraging for people just getting into software engineering.

So please continue creating awesome tools like this and share it with us all and don't be discouraged. We all love to see tools like this. :)
