Who it's for

DevOps, SRE, platform, and security teams operating cloud infrastructure and applications who need a single place to monitor system health and troubleshoot issues.

What you get

A unified observability platform combining infrastructure monitoring, application performance monitoring (APM), log management, network and database monitoring, and cloud security (threat detection, vulnerability management). It provides prebuilt and customizable dashboards, alerting/notifications, and AI-assisted investigation features (Bits AI) for anomaly detection and root-cause analysis. Covers cloud, container/Kubernetes, and serverless environments through hundreds of integrations.

How it works

You install the Datadog Agent or configure integrations across your hosts, containers, and cloud services to collect metrics, traces, and logs. That data streams into Datadog, where it's correlated in dashboards, and you configure monitors/alerts that notify your team when thresholds or anomalies are detected. Pricing is subscription-based (SaaS), typically per host/resource with usage-based add-ons for logs, APM, and more.

Where Datadog stands out

Verified capabilities most alternatives don't have.

Tracing / APM only 2 of 7 apps
Log aggregation only 3 of 9 apps
