Free vs Paid Uptime Monitoring: What You Actually Need

Don't Pay for Features You'll Never Use

The uptime monitoring market is full of plans that bundle dozens of features — most of which a typical website owner never touches. Before you hand over a credit card, it's worth understanding what actually moves the needle.

What Genuinely Matters

For 95% of websites, effective monitoring comes down to a short list:

• Frequent checks — the shorter the interval, the faster you detect outages
• Reliable alerts — delivered where you'll actually see them
• SSL expiry warnings — an expired certificate = full outage
• Response time tracking — slow is the new down
• Incident history — so you can spot patterns

Notice what's not on that list: complex synthetic transaction scripting, multi-region probe networks, and per-seat enterprise dashboards. Useful for some — overkill for most.

What You Get Free with ismysiteup

For a small site, that covers the essentials — at no cost. ismysiteup also flags SSL certificate and domain expiry before they turn into outages; see the pricing page for what each plan includes.

When Paying Makes Sense

Paid tiers earn their keep when you have:

• More than a handful of sites or endpoints — Pro covers 50 uptime monitors ($9/month) and Business 200 ($24/month)
• Pages where every minute counts — Pro checks every minute, Business every 30 seconds
• Business numbers to watch — more Data Monitors (10 on Pro, 50 on Business) to catch orders or signups that quietly stop

If your needs go further — multi-region verification for strict SLAs, or on-call rotations with escalation policies — you'll want a tool built for that. If not, you're better off putting that budget elsewhere. (Wondering what "99.9% uptime" in an SLA really means? We did the math.)

The Honest Recommendation

Start free. Monitor your critical URLs, connect your alerts, and run it for a month. You'll quickly learn whether the free tier covers your needs (for most people, it does) or whether you've genuinely outgrown it.
