A NoScript equivalent for Safari! This app blocks JavaScript on any website. It blocks most: • Ads • Newsletter popups • Cookie requests • Wasted megabytes of third-party JavaScript libraries When you encounter a website with too much JavaScript, just tap share → JavaSnipt → refresh, and voilà! No more interactivity. Alternatively, you can use JavaSnipt to block JavaScript on *all* websites and allow only sites you trust. It's up to you! Some sites, like YouTube, will not work with JavaScript blocked. That's why JavaSnipt targets only sites you select. By purchasing JavaSnipt for iOS, you will also unlock JavaSnipt for macOS. Your blocked sites sync between all your devices via iCloud. The web has too many popups and third-party scripts. It wasn't designed to respect your privacy, battery life, data cap or phone-sized screen. Take back control with JavaSnipt. (The crab is Snippy, our mascot. Think of this app as him snipping away the extra JavaScript!)

Verdict
The clearest difference is review sentiment: StopTheScript at 70% against JavaSnipt's 53%. StopTheScript also leads on ratings volume (31 vs 6) and iOS requirement (15.0 vs 26.0). JavaSnipt's advantage is rating (4.7 vs 4.5) and price ($2.99 vs $5.99). On update cadence, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
JavaSnipt costs $2.99 and StopTheScript $5.99 up front. Neither carries in-app purchases, so what you see is what you pay.
JavaSnipt holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: StopTheScript has 31 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 53% of JavaSnipt's written reviews are positive against 70% of StopTheScript's, so the app with the better star average is not the one people write more warmly about.
JavaSnipt ships an update every 5 months, StopTheScript every 4 months. The most recent releases landed on September 15, 2026 and September 20, 2026 respectively.
