Datadog vs Healthchecks.io Pricing (2026)

Which one is cheaper?

Healthchecks.io is the cheaper option, starting at $5/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 Healthchecks.io goes with flat-rate. 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. Healthchecks.io: This is the budget end of the uptime/cron monitoring category — tools like PagerDuty or Datadog operate in a totally different price universe. Healthchecks.io is clearly courting solo developers and small teams who want dead-simple monitoring without enterprise bloat or per-seat penalties.
