Very good and more stable than Tamperamonkey/Violentmonkey. It also works with Edge canary on Android, but unfortunately the icons such as “run on startup” are hidden in the browser bar.

Does one thing and does it right. This is the code injection extension you're looking for.

Great extension, I love that I can find the same features and shortcuts as in VS Code, it's really a great experience ^^

John Hines

Holy Cow...this is a good one

Marcello V.

wow!

Bob Marshall

Was looking for an MV3 alternative to Stylus. Tried a few, this one is my favorite by far. Lightweight, simple UI, does everything I need.

FrontEnd Neo

Perfectly worked for my requirements. Thanks. Much appreciated.

Gabrielius Liaškus

A high-quality and stylish Chrome Extension that injects JS and CSS just perfectly!

Nitigya Joshi

Works most of the time but sometimes it caches the old code and even after multiple changes, they don't get reflected on the site.

Andreas Sefzig

This is one of my most frequently used tools. Love the purpose, usability and the constant, seamless improvement. Kudos to the developer: you are part of my internet, my work and my workflows, <3.

Very useful

Greg Perham

Just started using it. Very nice. One thing that would make it more perfect is if the CSS updated in open tabs upon save. The Programmatic Injection implies that it will load edits without reloading open tabs, but my experience is that the styles either do not get injected at all, or still require the tab to be refreshed.

Great tool - allowed me to customoze and improve some manual work on website that is not mine :)

Максим Покровский

Incredibly well-executed product with a sleek design, well-written code, and an intuitive UI. It has solid documentation and not-commerciall yet. I hope it would be open-sourced on GitHub to build more trust, ensuring it doesn’t follow the unfortunate path that Stylish did. Anyway If you're looking for an extension that allows you to tweak your favorite websites, look no further.

Modassir Hossain Rajib

Had to jump in to the webstore, only to write this review. Absoulutely loving the new update! Been using this extension for nearly 4 years now. Brilliant work, keep it up!!

Egon Freeman

The new look is very nice... however, it was much easier to see which script was enabled or not with the previous layout. Is it possible to have an option to always show enabled/disabled indicator? Also, is there an option to disable cloud uploads entirely, or have the ability to disable cloud uploads on all scripts? Having it default "Off" would also probably be a good idea. I don't know whose cloud that is or where it is, but I do not consent to any of my stuff being uploaded anywhere without my PRIOR consent. Also, is it possible to have multiple scripts on the same page, or one script on multiple pages yet? Setting things up for "domain.tld", then "domain.tld/*", then "*.domain.tld" and "*.domain.tld/*" just to make them distinct is getting old.

Elisei Kulikovsky

Excellent update!

Peter H 2

This tool has been amazing. However, after the latest update I am unable to save any changes. EDIT: I've found that I need to add something to the Javascript section to be able to save the CSS. So I just put a space into the JS.
