New Relic Synthetic Monitoring vs Datadog Synthetic Monitoring

Free tier available

From $5 per 1k API test runs / 12 USD per 1k browser test runs (indicative)

The free tier is genuinely usable. Costs come from full-platform user seats rather than check volume.

Priced per test run and separately for browser versus API. Costs land inside a wider Datadog contract that is rarely small.

100 GB of data ingest and one full-platform user free every month, permanently.

14-day trial.

• The most generous permanent free tier of any major observability platform.
• Synthetics, APM, logs and RUM under one bill and one query language.
• Scripted browser monitors use standard Selenium-style JavaScript.

• Correlation with APM traces and logs makes root-cause analysis dramatically faster.
• Private locations let you monitor internal services behind the firewall.
• Recorded browser tests are authorable by people who do not write code.

• Per-user pricing for full-platform access surprises teams that want wide visibility.
• The interface is dense and takes time to navigate confidently.
• Synthetics is less differentiated than Datadog's correlation story.

• Only worth it if you are already a Datadog customer; standalone it is expensive.
• Datadog billing complexity is a well-known source of budget surprises.
• The recorder produces tests that are harder to version and review than code.
