THE SHORTLIST / SEVEN TOOLS TO CONSIDER

Which uptime monitoring tool fits your services?

An uptime-only brief, an on-call team, and a website-health audit call for different tools. Use this shortlist before reading our narrower Sandglass vs Pingdom comparison.

Selection: tools with public product documentation relevant to this workflow. Fit notes are editorial judgments, not a measured ranking. Vendor pricing and feature pages were checked on 28 October 2026. The tool names link to the pricing sources. Amounts retain their listed currencies; annual equivalents require annual billing. Taxes, regional prices, and plan limits can change.

Seven uptime tools: entry limits, monitoring scope, and tradeoffs
Tool / pricing sourcePublished price or allowanceWorkflow and tradeoffs
Sandglass — author-ownedFree: 5 checks, 60-second interval, 7-day incident history. Basic: $9.99/month paid monthly or $99.90/year; 20 checks at intervals down to 20 seconds.

Availability checks, response trends, incident history, status pages, SSL, and heartbeat checks on applicable plans.

Our small-site pick when recurring cost and check frequency lead the brief. The check allowance is shared across check types; decide how many website, certificate, and scheduled-job checks you need.

PingdomEntry Synthetic Monitoring: $18/month paid monthly or $198/year ($16.50/month equivalent); 10 uptime checks, 1 advanced check, 50 SMS alerts.

Uptime monitoring plus transaction and page-speed monitoring in a broader synthetic toolkit.

Consider when transaction monitoring and a broader synthetic workflow matter. Real User Monitoring is a separate purchase; the entry package is not feature-identical to Sandglass Basic.

UptimeRobotFree: 50 monitors with 5-minute checks, listed for personal and commercial use.

Website, keyword, port, ping, and scheduled-job monitoring, with status-page options.

Useful when monitor count matters more than frequent checks. A five-minute schedule can leave a short outage between checks; compare a paid plan if faster detection matters.

Better StackFree personal-project tier: 10 monitors and heartbeats, plus 1 status page.

Uptime monitoring tied to incident management, on-call escalation, and team response.

Compare when the important question is who gets paged and how incidents are handled. The free tier is labelled for personal projects; evaluate commercial and responder pricing separately.

StatusCakeFree: 10 uptime monitors with 5-minute checks, plus 1 SSL, 1 domain, and 1 page-speed monitor.

Availability and website-health checks across uptime, certificates, domains, and page speed.

Consider for a small mixed set of website checks. The uptime quantity alone does not describe the other product allowances, and the free check interval is slower than Sandglass Free.

Uptime.comThe pricing calculator’s displayed entry configuration is $108/year ($9/month equivalent); monitor quantities and selections change the quote.

Website/API availability, synthetic transactions, heartbeats, and real-user monitoring products.

Consider when several monitoring types need one vendor. Configure the exact checks and billing period before comparing a quote: the calculator’s starting price is not a universal monitor allowance.

Oh DearThe Solo tier covers 2 websites; larger tiers raise the website allowance.

Uptime, SSL, broken links, application health, and scheduled tasks in a website-health bundle.

Consider if broken links and application health matter alongside outages. Count websites and needed checks, rather than comparing its site-based allowance directly with another vendor’s monitor count.

01 / FOUR PRIORITIES. ONE FAVORITE.

Sandglass vs Pingdom:
costs, checks, and intervals.

Our brief: keep ongoing costs low, cover a handful of services, and check them frequently. This compares Sandglass Free and Basic with Pingdom's entry Synthetic Monitoring package. These are published plan specifications.

Four selected priorities for small-site uptime monitoring
What we're choosing forOUR PICKSandglasssandglass.itPingdomEntry Synthetic Monitoring
An ongoing free startSANDGLASS WINSFree forever: 5 checks, 60-second minimum interval, and 7-day incident retention. [1]A time-limited free trial; the pricing page lists paid subscriptions rather than a permanent free tier. [2]
Lower entry subscription priceSANDGLASS WINSBasic: $99.90/year on annual billing, or $9.99/month billed monthly. [1]Entry Synthetic: $198/year on annual billing ($16.50/month equivalent), or $18/month billed monthly. [2]
More entry-level uptime capacitySANDGLASS WINSBasic: 20 total checks across up to 3 groups. Different check types share that allowance. [1]10 uptime checks, plus 1 advanced check and 50 SMS alerts in the entry package. [2]
Shorter paid check intervalsSANDGLASS WINSBasic: 20-second minimum interval. [1]Uptime checks as often as 60 seconds, according to Pingdom's outage-monitoring page. [3]

USD list prices, checked . Pingdom's US pricing is for Synthetic Monitoring alone; Real User Monitoring is a separate product. Prices may vary by region and tax treatment. These bundles have different features. Check intervals describe scheduling, not guaranteed detection or notification times.

02 / SAME BILLING PERIOD. SIMPLE ARITHMETIC.

How do annual subscription costs compare?

Compare the two entry subscriptions on annual billing. For a small-site brief centered on uptime checks, that's a useful difference to put back into the product you're building.

THE ANNUAL SUBSCRIPTION RECEIPT

Pingdom entry Synthetic
$198.00
Sandglass Basic
− $99.90
Lower annual bill
$98.10

Derived from the published annual prices above. This is a subscription-price difference, not a claim of identical feature coverage.

03 / BUILT A WEBSITE? KEEP AN EYE ON IT.

Which Sandglass features cover your website?

Availability and response trends.

Sandglass describes uptime monitoring with configurable retries and response-time tracking. That's the everyday visibility we'd want for a client site or a small SaaS. [4]

Watch the quiet failure modes.

Basic also lists SSL certificate monitoring and heartbeat/cron monitoring. Useful when a certificate or a scheduled job needs attention alongside the public website. [1]

Give customers a place to look.

Hosted status pages show live status, incident context, and historical uptime. We like turning monitoring into something useful for customers, too. Pingdom also includes public status pages. [4] [5]

THE VERDICT / OUR KIND OF UPTIME

When should you choose Sandglass?

A free start, a lower entry price, more room for uptime checks, and a shorter paid interval. Those are our priorities. That's our winner.

Give Sandglass a go

Start with the free plan. The shorter interval, certificate, and heartbeat features discussed above require Basic or higher.
