Datadog Synthetics review: excellent, if you are already paying Datadog

Datadog Synthetics is a serious synthetic monitoring product sitting inside one of the most capable observability platforms there is. The reason to choose it is almost never the monitoring itself — it is that a failed check lands next to your traces, logs and infrastructure metrics. The reason to think twice is the billing model, and specifically one detail about how a test run is counted.

Is Datadog Synthetics worth it?

If you already run Datadog, yes — correlating a synthetic failure with the trace and the host metric from the same second is genuinely valuable and no standalone tool can do it. If you do not, this is an expensive way to buy uptime checks. Budget with care: you are billed per test run, and a run means one execution from one location, so checking from three regions triples the number you are paying for.

4.0/ 5
Powerful in context, costly out of it Our assessment, written by the team behind a competing product — read it as an informed opinion, not a neutral audit. Every factual claim is checked against Datadog Synthetics's own public pricing and documentation at the time of writing.
Overview

What Datadog Synthetics is

Datadog Synthetics runs API tests and browser tests on a schedule from Datadog's global locations, or from private locations inside your own network. API tests assert on status, response body and timing; browser tests script multi-step user journeys.

Its real advantage is not the checks but the context around them. A failing synthetic test in Datadog is linked to the traces, logs, host metrics and deployments from the same moment, so the question moves from "it is down" to "it is down because of this deploy" without leaving the screen.

Pricing is per test run, and this is the part people misjudge. A test run is one execution of one check from one location. The same check running every minute from three locations produces three runs a minute, not one — so the bill scales with frequency and locations multiplied together, not with the number of checks you created.

Capabilities

What Datadog Synthetics does well

Monitoring that arrives already correlated with everything else.

Correlation with the whole platform

A failed check sits beside traces, logs, infrastructure metrics and deploy markers. For diagnosis rather than detection, nothing standalone competes.

Browser tests with recorder

Multi-step journeys, recordable rather than hand-written, which lowers the barrier compared with writing test code.

Serious API testing

Assertions on status codes, response bodies, headers and timings, with multi-step API workflows.

Private locations

Run checks from inside your own network for systems that are not publicly reachable.

Global location coverage

A wide set of managed locations, with the caveat that each one you add multiplies your run count.

Alerting into existing on-call

Monitors, escalation and integrations shared with the rest of Datadog, so nothing new to wire up.

Cost

What Datadog Synthetics costs

Per test run, on annual commitment. List prices below; enterprise discounts are common.

Item List price Notes
API test runs $5 per 10,000 Annual commitment
Browser test runs $12 per 1,000 Annual commitment; roughly $15-18 on pay-as-you-go
A "test run" One check, one location, one execution Three locations means three runs per interval
Typical enterprise spend $10,000-50,000/yr For 50-200 endpoints, often inside a wider Datadog agreement

Monitoring vendors change plan limits and prices frequently and without announcement. Every figure here carries a "verify on their site" caveat and you should take it seriously before making a decision on cost.

The balance

Where it is strong, and where it is not

What works

  • Synthetic failures correlated with traces, logs and infrastructure metrics.
  • Strong browser and API testing, with a recorder for journeys.
  • Private locations for internal systems.
  • Shares alerting and on-call routing with the rest of Datadog.
  • Enterprise discounts of 30-40% are common within larger agreements.

What to watch out for

  • Billed per test run, so frequency and locations multiply the cost together.
  • Browser runs at $12 per 1,000 make frequent journey testing expensive quickly.
  • Little reason to buy it if you are not already a Datadog customer.
  • Certificate and domain expiry are not first-class monitor types.
  • Cost forecasting requires modelling, not reading a plan.
Fit

Who Datadog Synthetics is for

Choose it if

  • Existing Datadog customers who want checks correlated with their telemetry.
  • Engineering teams diagnosing failures rather than only detecting them.
  • Organisations with internal systems needing private location checks.
  • Enterprises with a negotiated agreement that absorbs synthetics into it.

Look elsewhere if

  • Anyone not already inside the Datadog platform.
  • Small teams who need availability checks cheaply.
  • Buyers who need a predictable fixed monthly cost.
  • Teams whose main concern is certificate and domain renewals.

Where MonitoringDaddy fits

These products answer different questions. Datadog tells you why something broke by putting the check beside the trace, the log line and the deploy. We tell you that something broke. If diagnosis is the job, we are not in the running and no price comparison changes that.

Our case is the cost of simply knowing. A hundred monitors with us is $34 a month, fixed, whatever they check and however the month goes. Their equivalent depends on runs, frequency and how many locations you picked, and browser journeys at $12 per thousand runs add up faster than most people model.

We also treat certificates and domains as first-class monitor types with their own expiry windows, which Datadog does not. And we check from one location, where they check from many — that is their advantage, and it is also part of why their bill moves.

The honest split: an observability platform where checks are one signal among many — theirs. A fixed, small bill for knowing that a set of sites, certificates, domains and pages are still fine — ours.

FAQ

Datadog Synthetics review: your questions answered

How much does Datadog Synthetics cost?

List pricing is around $5 per 10,000 API test runs and $12 per 1,000 browser test runs on annual commitment, with pay-as-you-go browser runs closer to $15-18 per thousand. Enterprise discounts of 30-40% are common. Verify with Datadog.

What counts as a test run?

One execution of one check from one location. This is the detail that surprises people: a check running every minute from three locations generates three runs per minute, so locations and frequency multiply rather than add.

Is it worth it if I do not use Datadog?

Rarely. The product's advantage is correlation with the rest of the platform. Bought alone it is an expensive way to acquire uptime checks that cheaper tools handle well.

Does it monitor SSL certificates?

Certificate state can be asserted within tests, but certificate and domain expiry are not first-class monitor types with their own alerting windows the way they are in dedicated tools.

Can it check internal systems?

Yes, through private locations that run checks from inside your own network.

How do I control the cost?

Reduce check frequency, reduce the number of locations per check, and be selective about browser tests. Browser runs are more than twenty times the unit cost of API runs, so that is where the money goes.

Does it do real user monitoring?

Datadog offers RUM as a separate product. Synthetics covers scripted checks; RUM covers actual visitor sessions, and they are billed separately.

How does it compare with MonitoringDaddy?

They correlate failures with traces and logs, which we cannot do at all. We charge a fixed $34 for 100 monitors including certificates, domains, page content changes and heartbeats, with nothing metered.

Nothing metered, nothing to model.

Datadog is better at diagnosis. We are a fixed monthly bill for knowing something broke — from $5 a month.
