Ever find yourself viewing a webpage when something annoyingly pops up, like an ad, or paywall, or a prompt to sign up for a newsletter? Or maybe you notice that even after the content has loaded, something is still using your network connection?

Enter no.js, a tool that helps you effortlessly, and temporarily, disable Javascript for the page you're viewing.

Easily prevent popups, tracking or analytics services, ads, and some paywalls. No need to go into your Safari settings and disable Javascript, only to immediately return to enable to. No need to strengthen content blockers, only to loosen them up again. Just two taps from any Safari view.

** No.js is NOT a content blocker. It is an extension that works in all apps that allow sending URLs to other apps. This means almost any app that has a way to view webpages, but actual mileage may vary. Also, some pages may appear broken when viewing them without Javascript, but good websites won't :)

What’s New

Version 1.4.1

Safari in iOS 14 sometimes activates share extensions inconsistently. This build makes that activation a bit more flexible. Thanks to Benjamin for the nudge to fix it.

Well worth it

This app works as advertised to stop JavaScript from running. Makes it much more pleasant to browse websites bloated with ads and other junk.

Works but...

As an iPhone 4s and IPad 2 owner, I've become increasingly frustrated with JS-bloated sites crashing Safari. Searched the App Store to see if there's anything that will let you turn off JS in Safari with a single tap. Thought I'd give this a try.

While I appreciate the author's effort with No JS, I find that the amount of time involved -- No JS launches an app and reloads the page in a stripped down browser -- is often much slower than simply going to Settings > Safari > Advanced > JS. Sometimes the No JS sequence doesn't seem to work at all, probably because Safari is choked and frozen.

Will Apple allow you to directly toggle a Settings setting from Safari? Seems to me a simple on-off tap would be the best way to stop crap JS from hosing your session.

Still, some users might find this app useful. For myself, I'm mostly browsing entirely with JS turned off in Safari.

Pretty disappointed

I was expecting this app to allow me to load a safari content blocker to block javascript permanently on a per site basis. Instead this app opens the page up in its own interface w/ scripts disabled, but has no option for blocking scripts in safari itself. I guess this is useful for pages that you will only visit once, but not if you want to continually visit a page with no scripts.

Now instead I’m using AdGuard pro and manually punching in the rules to block scripts.
