TL;DR
Jscrambler vs Script Monitoring
WHAT THEY DO WELL
JavaScript obfuscation and code protection is their original product and is genuinely best in class. Nobody else in this comparison competes with it.
WHERE TO CHECK CAREFULLY
Trap-based detection runs in the page, so the detection logic is visible to anything else running there. A script written to ignore decoy objects is not caught by them.
PRICING
Jscrambler is quote-based. Ours is published, from $99/month, with a free plan.

Is Script Monitoring a good Jscrambler alternative?
Yes, if your primary driver is PCI DSS 6.4.3 and 11.6.1 evidence and you want published pricing and a free plan to evaluate on. You want JavaScript obfuscation and anti-tamper protection for your own application code. That is their strongest capability and it is not something we do at all. The rest of this page sets out where each product is genuinely stronger, with a capability table, so you can make the call on your own constraints rather than on ours.
Where Jscrambler is strong
Taking this seriously, because a comparison where the other product has no advantages is not a comparison. These are real and they may well be decisive for you.
JavaScript obfuscation and code protection is their original product and is genuinely best in class. Nobody else in this comparison competes with it.
Webpage Integrity uses decoy objects and in-page monitoring to detect scripts interacting with sensitive elements, which is a real detection technique.
Long track record in the category and a substantial engineering team behind the product.
Strong presence in regulated industries, and used to detailed security review processes.
Where Jscrambler has limits
Equally honestly, and stated as things to verify rather than as accusations.
Trap-based detection runs in the page, so the detection logic is visible to anything else running there. A script written to ignore decoy objects is not caught by them.
Their AI analysis features have historically relied on third-party model APIs, which is why they are opt-in. If your data governance forbids sending script contents to a third-party model, check this carefully.
Code protection and client-side security are two products. If you only want the second, you are buying into a platform built primarily around the first.
Quote-based pricing with no published figures, so evaluation requires a sales cycle.

Which one to choose
J
Choose Jscrambler if
You want JavaScript obfuscation and anti-tamper protection for your own application code. That is their strongest capability and it is not something we do at all. For PCI script monitoring, its trap-based detection runs in the page, so a script written to ignore decoys is not caught by them.
Choose Script Monitoring if
Your driver is PCI DSS 6.4.3 and 11.6.1, you want the two requirements evidenced separately, and you would rather start on a free plan than run a procurement cycle to see the product. It also hashes each script server-side, with unlimited domains on every plan and full integrations on every paid plan.

FAQ
Frequently asked questions
Yes, for teams whose primary driver is PCI DSS 6.4.3 and 11.6.1 evidence, who want published pricing, and who want to evaluate on a free plan rather than through a sales cycle. You want JavaScript obfuscation and anti-tamper protection for your own application code. That is their strongest capability and it is not something we do at all.
No, and neither does most of this category, which is part of why comparing them is hard. Our pricing is published: free for 1,000 page views a month, Pro from $99/month, overage at $0.0013 per page view.
Yes, and for some combinations it is sensible. Running two client-side tools on the same payment page adds weight, so it is worth being deliberate about which one is the system of record for your PCI evidence and which is doing something else.
Yes, and it is worth asking every vendor in this category the same question. Our tag is integrity-checked on load: if what arrives in the browser is not the script we published, it does not run. A client-side monitor that an attacker can silently modify is worse than no monitor, because it keeps reporting all-clear while the page is compromised. Not every agent in this category does this, so put it to Jscrambler as well.
Yes, this is the right thing to worry about, and the answer is that it should not. Installation is one first-party tag with no DNS or CDN change, and the tag is fail-open, so if our service is unavailable your page still renders. Most teams run monitor-only mode alongside their existing tool for a few weeks before switching the system of record.
Usually days rather than weeks. The tag goes in, you mark your payment pages with selector rules, and the inventory populates from live traffic immediately. The slower part is re-recording business justifications, and if you already wrote them for 6.4.3 they transfer directly.
Jscrambler does not publish pricing. Among tools that publish prices for PCI DSS 6.4.3 and 11.6.1: Script Monitoring is free for 1,000 payment-page views a month and $99/month (or $990 a year) for 100,000, with unlimited domains; cside is free for 2,000 payment-page views a month and $99/month for 100,000; DomDog is $999 a year for 100,000 page views on one domain and two payment pages; Source Defense Essentials is $98/month for 100,000 page views on one domain; Report URI's PCI features start on its $164.99/month plan; and if your traffic is already on Cloudflare, Client-Side Security Advanced is $0.099 per 1,000 requests. Which is cheapest depends on your page views and how many domains you need.
