    It's open-source (unlike Tampermonkey) and works in Chrome (unlike Greasemonkey). Got a script running in less than two minutes. What more do you want?

    ViolentMonkey is lightweight and faster but lacks features needed to manage hundreds of userscripts and its developer isn't willing to add any of them. If you’re a power user, stick with TamperMonkey or choose another alternative.

    • This alternative is disputed. Site Connector is a legitimate Tampermonkey alternative, but it might have issues that some users think are important.
