## TL;DR
- SiteGuardian wins for one storefront; Datadog wins for an IT estate. Datadog is the platform-level observability incumbent — synthetic monitoring, infrastructure monitoring, APM, log management, RUM, and 25+ products priced by consumption. Per the Datadog pricing page on August 2026, Synthetic Monitoring is sold in SKUs: SYNTHETICS-1K at $12/mo annual per 1K runs, SYNTHETICS-10K at $5/mo annual per 10K runs/mo, CI-APP-TEST at $79/mo annual per 1K runs, and CI-MOBILE-APP-TEST at $50/mo annual per 1K runs.
- When Datadog: you run an infrastructure estate — services, hosts, containers, RUM sessions, logs, custom metrics — and need consolidated observability with platform-level alerting and a vendor-backed integrations catalog.
- When SiteGuardian: you have one storefront and want uptime, SSL expiry, broken-link coverage, checkout-failure monitoring, and form-failure monitoring in one inbox at three flat tiers in USD.
- The verdict: Datadog for IT estates; SiteGuardian for one storefront.

## Buying-time FAQ
- Q: Is Datadog the same as SiteGuardian?
  A: No — they are different products at different scopes. Datadog is the platform-level observability incumbent — synthetic monitoring, infrastructure monitoring, APM, log management, RUM, security monitoring, CI visibility, and 25+ enterprise-shipped products priced by consumption. Datadog is built for an IT estate. SiteGuardian is the URL-side monitor for a one-founder Shopify, WordPress, Squarespace, or Wix shop.
- Q: Does Datadog have a free tier?
  A: No — Datadog does not ship a free Synthetic Monitoring tier. Per the Datadog pricing page on August 2026, Synthetic Monitoring is sold only as paid consumption SKUs. The "Start Free" offer across the pricing page is the platform-level 14-day trial. The trial is not a free tier.
- Q: Does Datadog monitor broken links?
  A: No — Datadog does not ship a broken-link crawler or link-rot detector. Datadog customers who want broken-link coverage script a synthetic browser test that walks their URL list and pay per test run for it. A 5-minute synthetic that walks your site once from three locations burns ~26K runs per month and bills at the SYNTHETICS-10K annual rate (~$315/mo) before any APM license.
- Q: Does Datadog monitor SSL certificate expiry on my domain?
  A: No — not in the way SiteGuardian does. Datadog SSL covers inbound TLS to the Datadog SaaS platform, not your domain’s certificate renewal calendar. SiteGuardian ships SSL expiry monitoring on every paid plan as part of the base product.
- Q: Does Datadog watch my checkout?
  A: Datadog can — but you build it. Datadog Synthetic Monitoring lets you script an API or browser test against your checkout URL. SiteGuardian ships a dedicated checkout-path probe on every paid plan: add the checkout URL to SiteGuardian and a probe runs against it on the same cadence as the uptime checks.
- Q: How much would Datadog cost me for one storefront?
  A: More than SiteGuardian Starter, and more than SiteGuardian Pro, in almost every realistic configuration. The minimum useful Datadog synthetic on one storefront (three locations, 5-minute cadence) is ~26K runs/mo, or roughly $315/mo at the SYNTHETICS-10K annual rate.
- Q: Should I run Datadog and SiteGuardian together?
  A: Sometimes yes. If your shop has an underlying app that needs APM, traces, logs, and infrastructure observability, Datadog is the right product for the app layer. SiteGuardian is the right product for the URL-side checks.
- Q: Datadog vs SiteGuardian for agencies?
  A: Different scales. SiteGuardian Pro covers up to three sites / fifty URLs at one flat $39/mo bill. Datadog is the right pick when the agency manages IT estates for clients. The smallest possible Datadog subscription for one agency’s worth of URL-side probing still runs hundreds per month.
