PageExtender is a Safari Extension that injects CSS and JS files into websites, allowing you to customize your favorite websites to your needs.
When visiting a page, e.g. https://en.wikipedia.org/wiki/Apple, the Safari extension will inject the following files into the page if they are present in the CSS and JS folders that you specify:
This way you can take control of any website. Some examples of what you can do with it:
∙ Work around a page that disabled scrolling due to an ad blocker being detected or because you've reached the limit of your monthly free articles.
∙ Hide content that isn't relevant to you on websites you constantly use for work.
∙ Hide promoted content that your ad blocker didn't hide.
This version reduces the minimum macOS version to 10.12 and removes menu items that aren't used.

Works Perfectly for Userscripts
I've had no need to try the CSS injection capabilities, but I did need a substitute for Tampermonkey as of Safari 13, since App Extensions are now required. This fits the bill perfectly! It does have the downside that I need multiple copies (or symlinks) for a script to run it on multiple domains vs. just the script header doing that, but on the upside I can keep my scripts in iCloud and have them run on all my Macs without worrying about keeping them in sync! It's also much faster than Tampermonkey, but I think that's just because App Extensions run significantly faster than old-style extensions.
Works perfectly for my needs
What's more, it's an open-source solution. Absolutely wonderful.
With Family Sharing set up, up to six family members can use this app.
