TL;DR
DomDog vs Script Monitoring
WHAT THEY DO WELL
Accessible and straightforward, aimed at teams who find the enterprise platforms oversized for their situation.
WHERE TO CHECK CAREFULLY
Scanner-based coverage carries the usual limitation: a scheduled view from outside is not the session a real customer had, and targeted payloads are written for exactly that difference.
PRICING
DomDog publishes pricing: Business is $999 a year for 100,000 page views a month, one domain and two payment pages. Ours is $990 a year at the same volume, with unlimited domains and a free plan under it.

Is Script Monitoring a good DomDog 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 something lightweight and inexpensive, CSP management matters to you, and scanning coverage is acceptable for your risk profile. 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 DomDog 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.
Accessible and straightforward, aimed at teams who find the enterprise platforms oversized for their situation.
Combines scanning with CSP management, which covers two related jobs in one place.
Lower commitment than the enterprise options in this list.
Where DomDog has limits
Equally honestly, and stated as things to verify rather than as accusations.
Scanner-based coverage carries the usual limitation: a scheduled view from outside is not the session a real customer had, and targeted payloads are written for exactly that difference.
Small public footprint, with limited independent technical material available to evaluate.
Verify directly whether the output meets what your assessor expects for 6.4.3 and 11.6.1 evidence.
Business is $999 a year for up to 100,000 page views a month, covering one domain and two payment pages.

DomDog pricing, and ours
DomDog publishes pricing. Business is $999 a year for up to 100,000 page views a month, covering one domain and two payment pages.
We publish ours: free for 1,000 page views a month, Pro from $99/month for 100,000 payment-page views, $499/month at 500,000 and $799/month at 1,000,000, overage at $0.0013 per page view, annual billing at 10 months instead of 12, and Enterprise on request.
Compare the domain and payment-page limits alongside the headline figure, because that is where the two plans differ most.

Which one to choose
D
Choose DomDog if
You want something lightweight and inexpensive, CSP management matters to you, and scanning coverage is acceptable for your risk profile. The trade-off is that a scheduled scan is not the session a real customer had, and it cannot block a script at runtime.
Choose Script Monitoring if
You need session-level coverage and the ability to block, or your assessor has said a scanner is not sufficient. It sees every real session and can block at runtime, 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 something lightweight and inexpensive, CSP management matters to you, and scanning coverage is acceptable for your risk profile.
Yes. Business is $999 a year for up to 100,000 page views a month, for one domain and two payment pages. Ours is published too: free for 1,000 page views a month, Pro from $99/month, overage at $0.0013 per page view. Compare the domain and payment-page limits, not just the headline figure.
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 DomDog 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.
DomDog is already one of the cheaper options at $999 a year for 100,000 page views, one domain and two payment pages. 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; 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.
