Datadog is a SaaS observability and security platform for cloud applications. It combines infrastructure monitoring, application performance monitoring, log management, and user experience analytics. Teams use it to troubleshoot incidents, track performance, and secure distributed systems.
Free Infrastructure plan for up to 5 hosts; paid plans are modular. Infrastructure starts around $15 per host/month billed annually, APM around $31 per host/month, Logs from about $0.10 per GB ingested plus indexing fees, and Synthetics/RUM are usage-based. Security, CI visibility, and other modules add separate per-host or per-event charges.
Proprietary
Datadog is strong for teams that want a single platform for observability and security. Its breadth and integrations are a major advantage, but modular pricing requires careful budgeting and tagging. It is best for cloud-native, SaaS, and engineering-heavy organizations that need deep visibility across services and infrastructure.
