Easier to use than TamperMonkey or GreaseMonkey

Easy to use, good UI design & feature set. Perfect.

It seems to work but it's not possible to instert HTML in the page. The code is insert at the beginning of the page.
I hope you will add the possibility to simply "edit" the page source code.

helpful. I using it to custom js and css of some chat tools that using on work :D

good

An absolute must-have for me! For the longest I didn't want to switch to Firefox because it lacked a good extension like this.

Very useful add on. Would love to see a version for android

Love it. Beautiful UI and exactly to the point

For a long time I was looking for a simple add-on that provides injection of code, not only js (css,html)
I love it
Already use it in many sites for adding elements in page improving site experience.

Thank you for this important add-on!

and Documentation in GitHub saved my time to understand it ^^

What's the point of this? It's 5 times larger than Greasemonkey and 70% larger than TamperMonkey.
