Frog find is a search engine used for old computers. Anything you search and any link you click gets converted into HTML. A demo can be found on https://search.unixfandom.com.

Here's how to install it. I'll show both the orginal link and my fork that includes some custom CSS for margins.

apt install php php-xml composer git
git clone https://github.com/peterunix/FrogFind.git
cd FrogFind
composer update
php -S localhost:8000
