Datadog vs UptimeRobot Pricing (2026)

Which one is cheaper?

UptimeRobot is the cheaper option, starting at $10/mo vs $18/mo for Datadog.

Can I use either one for free?

Both offer free plans, so you can try each without paying. Start with whichever fits your workflow better and upgrade when you hit the limits.

How do they charge?

Different approach here. Datadog uses usage-based pricing, while UptimeRobot goes with hybrid. That changes the math depending on your team size and usage.

Which one is a better deal?

Depends on what you need. Datadog: At $18-27/host, Datadog sits firmly in the premium tier of observability — more expensive than open-source stacks like Grafana + Prometheus, and pricier than New Relic's per-user model for many team sizes. They're not chasing budget buyers; they're targeting mid-market and enterprise engineering orgs that want a single pane of glass and are willing to pay for it. UptimeRobot: This is a budget-to-mid-market play — cheap enough that solo devs and small startups treat it as a no-brainer, but it's not chasing the enterprise observability crowd head-on the way Datadog or PagerDuty do. The lack of a free trial (just a 14-day refund window) signals they're confident the free plan does the trial's job for them.
