A Powerful Chrome Extension for Injecting JavaScript and CSS

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.

Perfectly worked for my requirements. Thanks. Much appreciated.

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

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.

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

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 :)

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.

how do i use it

Works perfectly! Keep it up?

Clearly the best extension to inject js on pages. Great job !

New design is so ugly

So nice！！！！

I'm really glad to find this extension. It really helps me a lot. Thank you so much for this great one!

Works like a charm. Beautiful interface too ?

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!!

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.

Excellent update!

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.

Very easy to use and works perfectly. JQuery injection supported

Great extension, I've been using it for years. One recommendation for the next update: It seems to not detect the URL changes on single page apps, like Twitter for example. So if the script does not fire on the first child URL visited on a specific domain, it will not fire throughout the whole SPA, no matter the trigger URL is visited later.

extension site needs full dark mode. also seem to be having an issue with removing a site from the list. useful extension and looking forward to updates.

Tried 4 other extentions before. This worked

This is so much easier and better to use than Tampermonkey. Thank you! By the way, the donation option might have issues when trying to pay.

Wonderful implementation.

I would love if instead of CSS you would have SASS.

The "Cloud Storage" feature is awesome. It saved me after I had to remove and re-installed my chrome. I wonder why is not in the feature list.

Improvement idea: - Create an "awesome User Javascript and CSS" repo so everyone could share their scripts! - Sync with my Google Account Competitive edge - completely replaced Tampermonkey and it's super easy to setup. - I can ideally replace all extensions with this, by writing my own scripts - Kiwi Browser (Android) + This extensions = Super duper killer browser that does whatever automations and customization I want

It's the best.
