Doesn't work

Doesn't work on IOS, I activated it in safari and gave it permissions, i tried multiple scripts, none of them did anything, i tried force restart safari. There is no guide for IOS, only for macos, out of ideas.
Uninstalled it, bye.

Weirdly few reviews for one of the greatest safari extensions

Safari has far less extensions than Chrome or even Firefox. Userscripts are browser agnostic. This is the best userscript application. This is FOSS. How hard can a piece of software deserve 5 stars? This software deserves 6 stars. It’s sort of sad that userscripts aren’t more popular.

Programmer Stranded w/ Only An iPad? Get Your Soul Back w/ Userscripts

I've been sans computer or laptop for nearly 3 years. The amount of things I found myself unable to do was getting to be egregious and soul crushing. I think Shortcuts is alright, if you don't mind the worst and slowest workflow imaginable. Then, one day, the universe put Userscripts in my path, and my iOS has since started therapy for the amount of disrespect I've been able to give it! Seriously, you can accomplish an inordinate amount of stuff with this. I made a widget with a picture of orange soda, and when you press it, you are prompted to speak: you must ask it "Who loves orange soda?". In return, it says "KEL LOVES ORANGE SODA!". As for useful things, you can create Progressive Web Apps like I did with a small game engine that emulates a terminal and plays like a modern text adventure game. I've made an application for adding lore to my worldbuilding dictionary. I could go on, but I can't recommend Userscripts enough for fans of mayhem and people on deserted islands like me!

Excellent extension

This gem is exactly what I was looking for: a simple way to customize the look & feel of the websites I use daily. Well done, devs.

Doesn’t work

Did work at one point, doesn’t anymore which sucks. Just downloading Brave is a better alternative for now.
