If you've been using UptimeRobot's free plan to monitor your clients' websites, there's something you almost certainly missed buried in their Terms of Service update.
In October 2024, UptimeRobot quietly added a clause banning commercial use from their free plan. If you run a business, monitor client sites, or use UptimeRobot to protect a revenue-generating product, you're now in violation of their Terms of Service.
This wasn't front-page news. Most developers found out months later — or still haven't.
What the Free Plan Actually Looks Like Now
Here's the full picture for UptimeRobot Free in 2026:
- 50 monitors (HTTP, keyword, ping, port, heartbeat)
- 5-minute check intervals — fixed, no option to go faster
- Personal/non-commercial use only — this is now enforced in ToS
- No WhatsApp, Telegram, or Slack on the free plan
- 3 months of log history maximum
- Basic status page with UptimeRobot branding
The 50-monitor count remains generous. The check interval has always been the real limitation: 5 minutes means your site can be down for nearly 5 minutes before the first check even fires. With a second-region confirmation step, you might not know for 8–10 minutes.
What Happens If You Ignore the Commercial Use Ban?
Practically speaking: nothing, until it does. UptimeRobot doesn't proactively audit accounts. But they reserve the right to suspend any account in violation of ToS without notice. If your freelance business or SaaS depends on those monitors, a sudden account suspension at the wrong moment is a bad day.
The more important issue: you've been running your monitoring on an informal basis you can't rely on. For professional work, that's a real business risk.
Their Paid Plans Have Also Changed
UptimeRobot restructured pricing in 2025:
| Plan | Price (monthly) | Price (annual) | Monitors | Interval |
|---|---|---|---|---|
| Free | $0 | — | 50 | 5 min |
| Solo | $10/mo | $9/mo | 10–50 | 60 sec |
| Team | $45/mo | $38/mo | 100 | 60 sec |
| Enterprise | $82/mo | $69/mo | 200–1,000+ | 30 sec |
Notice the Solo plan starts at $9–10/month and still doesn't include WhatsApp or Telegram. For 30-second intervals, you're paying $69–82/month on Enterprise.
What UptimeRobot Still Does Well
To be fair: UptimeRobot is a mature, reliable product with 15+ years of history. Their monitoring infrastructure is globally distributed. If email and Slack alerts are enough, and you're on a paid plan, it's a solid tool.
Where it genuinely struggles for ASEAN and LATAM developers:
- No WhatsApp support on any plan — not as an add-on, not through native integration
- Minimum interval of 60 seconds on Solo — paid, but still slower than 30 seconds
- USD-only pricing — no IDR, BRL, or MXN billing
ndelog as an Alternative
ndelog Sentinel was designed specifically to fill these gaps. Key differences:
-
WhatsApp alerts from $2/month (Watchman plan) with unlimited messages
-
30-second intervals from $7/month (Warden plan)
-
Commercial use allowed on all plans including free
-
Free plan — no credit card required
ndelog's free Spark plan is deliberately smaller (15 monitors vs UptimeRobot's 50) because it's not meant to compete on volume — it's a genuine free tier that converts users onto paid plans built for professional use.
If you're currently on UptimeRobot Free and using it for client work, the honest path forward is either paying for UptimeRobot Solo ($9–10/mo) or switching to a tool where $2/mo gets you WhatsApp alerts and commercial use from day one.
