How does 'wappalizer' understand my weblog is made by Hugo?

My blog is hosted on Github and is built within Wercker. The Firefox addon, Wappalizer, can find that it’s built by Hugo, but how?!!

View the source of the page, and search for hugo, you will most likely find the meta tag with "generator" string in the HTML header. It’s a convention for Hugo themes to set the generator tag in the HTML headers.

It’s not a theme thing; Hugo adds it automatically to your top-level index pages, as the first item in <head>.


It can be a theme thing … we only add it if it’s not already there…

That explains why the generator tag doesn’t duplicate when I have it in my theme too :slight_smile:
