SiteGuardian vs Uptime.com. Uptime.com watches uptime; SiteGuardian watches uptime + SSL + broken links + checkout + forms.
Uptime.com watches uptime. It does not crawl your site for broken links on any tier. SSL ships on Basic Monitoring, but you wire status pages, synthetic transactions, and integrations as separate products. SiteGuardian ships uptime, SSL expiry, broken-link coverage, checkout-failure monitoring, and form-failure monitoring on every paid plan, in one inbox.
- One loud email when your site, checkout, or forms go down. No dashboard login.
- Permanent minutely probe cadence on the paid SiteGuardian plan.
- SSL expiry alerts on every paid SiteGuardian plan, included — same email as an outage.
- Watches the URL list you configured and re-probes it for broken links, in the same email.
- Watches your checkout and your contact form — alerts in the same email when either breaks.
- No free tier on SiteGuardian. You pay for the watch, by the month.
- Custom slow threshold per URL, set in plain English.
- Built for one founder, one inbox, one storefront.
When Uptime.com is the right fit
Uptime.com is the right fit when you want a public status page, root-cause analysis, synthetic transaction monitoring, and a routing surface that sends to Slack / MS Teams / PagerDuty / Opsgenie — and you are happy stacking modules.
When SiteGuardian is the right fit
SiteGuardian is the right fit when one inbox, $19 a month, and a flat pricing bill cover the entire reason you bought a monitor — and you want broken-link coverage plus checkout and form checks without recording a script.
Quick answer
SiteGuardian vs Uptime.com, in one paragraph.
SiteGuardian wins for the one-inbox storefront; Uptime.com wins for the enterprise routing surface. Uptime.com ships public + private status pages with custom sub-domain, root-cause analysis, alerting to Slack / MS Teams / PagerDuty / Opsgenie / webhooks, and 1-minute probe cadence on every tier (Basic Monitoring $9/mo monthly). It does not ship a broken-link crawler on any tier, and the dedicated checkout-path and form-path probes ship only as Synthetic Transactions paid Advanced Checks that require recording a Chromium script. SiteGuardian ships uptime, SSL expiry, broken-link coverage, checkout-failure monitoring, and form-failure monitoring on every paid plan, in one loud email.
What is SiteGuardian vs Uptime.com?
SiteGuardian is a paid URL-side monitor with one loud email per outage and three flat tiers. Uptime.com is an enterprise-leaning uptime monitor with public + private status pages, root-cause analysis, alerting into Slack / MS Teams / PagerDuty / Opsgenie, and 1-minute probe cadence on every tier. The two overlap on uptime and SSL; SiteGuardian adds the three URL-side checks (broken-link coverage, checkout, forms) Uptime.com does not run outside Synthetic Transactions.
Is Uptime.com better than SiteGuardian?
Uptime.com is better when you need public + private status pages with custom sub-domain, root-cause analysis, or alerting into an incident-routing surface (Slack / MS Teams / PagerDuty / Opsgenie) in the same product. SiteGuardian is better when one loud email and three flat tiers beat stacking modules and recording a transaction script.
Which is cheaper for one storefront?
Uptime.com Basic Website Monitoring is $9/mo monthly or $84/yr annual (~22% annual discount). SiteGuardian Starter is $19 a month for one site and ten URLs. Status Pages ship as a separate Uptime.com product from $13/mo. Across twelve months of paid use with the four URL-side checks, SiteGuardian Starter at $19/mo is the simpler pick; Uptime.com beats it once a status page and a routing surface become buying-time requirements.
Does Uptime.com monitor checkout failures?
Only via Synthetic Transactions, which require recording a Chromium browser script that walks the cart. SiteGuardian probes the checkout URL on the same cadence as your uptime checks and emails you when it goes slow or returns errors — no recorded script required.
Does Uptime.com have a free tier?
No. Uptime.com has moved away from named tiers to a Subscription Calculator; the entry point is Basic Website Monitoring from $9/mo monthly. There is no free tier on either product; SiteGuardian Starter is $19 a month for one site and ten URLs.

Honest pros & cons
What each tool genuinely does well — and where it’s rough.
Uptime.com
Pros
- 1-minute probe cadence on every paid tier — not gated to a higher SKU.
- SSL/certificate expiry alerts ship on Basic Monitoring at every tier (not a Standard+ add-on).
- Synthetic Transaction Monitoring simulates checkout and form submissions in a real Chromium browser, with screenshot-on-error and root-cause analysis on the transaction.
- Public + private status pages with custom sub-domain, password protection, and Google Search opt-out (priced as a separate product from $13/mo).
- Maintenance windows / scheduled maintenance built into every Website Monitoring tier.
- Root-cause analysis and alert log in the Reporting surface as standard.
- Unlimited users on every plan; alerting to Email / SMS / Phone / Slack / MS Teams / PagerDuty / Opsgenie / Discord / webhooks / Pushover / Pushbullet / Splunk On-Call / Datadog / Zapier.
Rough edges
- No broken-link crawler or site-audit feature on any tier — Uptime.com is an HTTP-ping product, not a crawler.
- Synthetic Transaction Monitoring requires recording a Chromium-browser script; it is not a "configure a URL" probe.
- The public pricing has shifted to a modular calculator — Basic Monitoring is $9/mo, Status Pages is $13/mo on top, Synthetic Transactions is a paid Advanced Check add-on — stacking the full product is closer to Uptime.com Standard tier than to Starter.
- 20+ integrations on the pricing page as of August 2026, not the previously quoted 80+; ecosystem depth has narrowed.
SiteGuardian
Pros
- Broken-link coverage on every paid plan, in the same loud email as an outage.
- One inbox, one email per outage — uptime, SSL, broken-link, checkout, and form signals stack into the same message.
- Per-URL slow thresholds on every plan, set in plain English.
- No per-monitor, per-seat, or per-check math. Three flat tiers.
Rough edges
- No free tier; you pay for the watch from the first URL.
- No public status page in the boxed product; no on-call rotation or incident timeline.
- No native routing to Slack / MS Teams / PagerDuty / Opsgenie — the inbox is the destination.

A one-founder Shopify, WordPress, Squarespace, or Wix shop that wants uptime, broken-link coverage, checkout-failure monitoring, form-failure monitoring, and SSL expiry in one loud email without instrumenting the storefront or recording a transaction script.
The verdict
Uptime.com for the enterprise routing surface; SiteGuardian for the one-inbox storefront.
A mid-market or enterprise team that wants a public status page, root-cause analysis, and a routing surface that fires into Slack / MS Teams / PagerDuty / Opsgenie, and is willing to stack modules to get there.
