1- you could have a open/free version and have a more specialize version that you charge a fee

2- you could sell a package with some of your project (3-4 for seem might go well together in some case) charge per parkage

3- charge for support to install

4- make a guide how to set up them on an hosting company (like bluehost) and link to a affiliate link to bluehost

5- build a free guide and a more advance one sell the advance one

6- create a course, sell it on udemy or on you site.

Why did you started this project ? Was there a hole in the market for that kind of need ? Try to find the old you and how he would buy that product. For the first project it seem it will probably need to stay free, the 3 other can probably be monetize. Check if there other product that are similar to your project and how do they monetize their product.

I was thinking along this line. PHPippo is of course free; I could have a page prompting visitors to 'submit your PHP script to get it instantly micro-optimized' or 'version checked'. But then I would basically charge users for something they could do themselves for free, so I would add a 'manual review' process to provide some added value. Even then, _would you trust a website you don't know with your sources?_ I don't know.

Perhaps there is room for 5- or 6-, as preprocessor directives are a powerful, yet tricky language, and might take some time to master.

I could try to sell a Wordpress/Drupal/Magento/etc. plugin based on the anti-scraping class - in fact there are a couple Wordpress 'security' plugins available for sale which are quite similar, though none of them addressing bad user agents/scraping bots.

I haven't though about plugins but that seem a great way to package some of your project. You can always have a free and paid tier with the free tier having limited fonctionalities.
