## What is StopTheScript?

StopTheScript is a Safari extension for iOS, iPadOS, and macOS that stops all JavaScript on your selected websites. StopTheScript is the only Safari extension that stops inline JavaScript on the web page as well as externally loaded JavaScript. This is in contrast to Safari content blockers, which can only block external JavaScript, not inline JavaScript.

### 5/5 — Fantastic Value and Function

*2026-08-06*

It’s great to see a highly useful app that still offers a one-time purchase option. This app fixes websites that would continuously crash in iOS (regardless of browser), even when I had my ad blocker turned off. Plus it disables most anti-ad-blocking features of websites. Note that using this app is a bit counterintuitive. By default it’s OFF on websites; you turn it on as needed on each site.

### 5/5 — Awesome

*2026-07-03*

I use this on my Mac and all iOS devices, it’s perfect for browsing all those “your ad blocker is stopping the page from loading” sites, simply enable it for that website when you see that message and they can’t tell if you’re using an ad blocker anymore.

Just don’t enable it on all websites

### 5/5 — Works Great

*2026-05-18*

It allows me to block JavaScript on all websites while allowing me to whitelist trusted websites or websites that do not abuse JavaScript.

### 5/5 — Must Have Extension

*2026-04-17*

I’m questioning the negative reviewers. It’s a fantastic app. IYKYK. Does exactly what you need it to do. Tested on a few articles and it works perfectly. Thank you!

### 2/5 — Good on macOS, but not great on iOS

*2026-04-10, version 3.1*

On macOS, you can disable javascript on all websites and only enable javascript on some websites that require it. However, iOS cannot do this. Yes there is a filter (in safari extension settings) in iOS where you can enable javascript for a select website and keep all other websites without javascript, but this is bugged for some reason and does not work unlike macOS.

So if you’re solely using this for macOS, this is a good app. However, if you need it for iOS as well, you should decide if you need the feature I explained. If that’s not important for you, then it’s good for iOS as well.

### 1/5 — Breaks YouTube?

*2026-03-22*

Horrible app. I installed it and went to YouTube which no longer loads. Deleted the app. Reinstalled again followed instructions EXACTLY. Same result.  Waste of money. Avoid John Gruber recommendations!!

**Developer response:** Did you allow StopTheScript on all websites? The instructions actually warn not to do that. Some websites do require JavaScript, including YouTube, so you don't want to allow StopTheScript there. Neither Gruber nor I recommended the extension for YouTube.

### 5/5 — The most efficient

*2026-01-05*

And less than 200kb!

### 2/5 — Could be better

*2025-12-11*

It’s functional, but virtually useless in the day to day. While I realize it is not encouraged to just block everything by default due to usability, concerns Blocking JavaScript by default is a measure that those who care about security and also has the perk of making your phone more intentional. I think it would be better to have forms of manually whitelisting. Instead of actively discouraging blocking. Great if you’re trying to read and bypassing paywalls but besides that very forgettable extension

### 5/5 — ちゃんと動く

*2025-11-18*

期待通り動いてくれる

### 5/5 — Works perfectly and easily!

*2025-10-12*

The extension works perfectly and easily!

(Providing one a) follows the steps described within in the app and b) disables JS on a website that still works without it. If one website is or all websites are broken, it’s an user error!)
