Report URI alternative: an honest comparison
Report URI collects and analyses Content Security Policy violation reports. It is excellent at that specific job, and it is honest about being that rather than a full client-side security product.

TL;DR
Report URI vs Script Monitoring
WHAT THEY DO WELL
The best tool available for CSP reporting, built by people who know the specification deeply. If you are deploying a CSP, this makes the process genuinely manageable.
WHERE TO CHECK CAREFULLY
It reports on policy violations. It cannot tell you anything about scripts your policy permits, and a compromised but allowed vendor generates no violation at all.
PRICING
Both publish pricing, which is rare in this category.

Is Script Monitoring a good Report URI 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 are deploying or tuning a Content Security Policy and want the best tool for that job. We would genuinely recommend them for it. 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 Report URI 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.
The best tool available for CSP reporting, built by people who know the specification deeply. If you are deploying a CSP, this makes the process genuinely manageable.
Transparent, developer-friendly and well documented, with a public pricing model rather than a sales process.
Also handles other browser reporting endpoints, not only CSP.
Honest positioning. They do not claim to be a PCI compliance product.
Where Report URI has limits
Equally honestly, and stated as things to verify rather than as accusations.
It reports on policy violations. It cannot tell you anything about scripts your policy permits, and a compromised but allowed vendor generates no violation at all.
No script inventory with business justifications, so it does not produce 6.4.3 evidence on its own.
No blocking beyond what your CSP itself enforces.
Complementary rather than competitive: most teams who need 6.4.3 evidence need both.

Which one to choose
R
Choose Report URI if
You are deploying or tuning a Content Security Policy and want the best tool for that job. We would genuinely recommend them for it. It reports policy violations only, so a compromised vendor your policy already allows generates no alert.
Choose Script Monitoring if
You need 6.4.3 and 11.6.1 evidence. These are complementary tools and running both is a reasonable answer. It flags an allowed vendor whose payload changes, 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 are deploying or tuning a Content Security Policy and want the best tool for that job. We would genuinely recommend them for it.
Yes, Report URI publishes pricing publicly, which is unusual here. Check their site for current figures rather than trusting a number quoted on a competitor's page.
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 Report URI 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.
Report URI publishes its prices, and its PCI features start on the $164.99/month plan. 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; 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.
