Netdata review 2026: real-time, per-second infrastructure monitoring with ML anomaly detection. Compare the free open-source Agent to Netdata Cloud pricing.
Netdata is an open-source infrastructure monitoring platform that collects and visualizes system, application, and container metrics in real time, at per-second granularity, with essentially zero manual configuration. It was created by Costa Tsaousis and is headquartered in San Francisco, California.
The core Netdata Agent is free and open source and can run entirely standalone on a server or edge device. Netdata Cloud is the company's commercial layer on top of that agent, centralizing dashboards, alerting, log management, and AI-assisted troubleshooting across fleets of monitored systems.
Netdata auto-detects running services and applications on a host and immediately begins collecting relevant metrics, backed by a library of more than 800 pre-built integrations for operating systems, databases, containers, web servers, and cloud platforms. Its per-second collection interval gives much finer visibility than the 30-to-60-second intervals common in other monitoring tools.
Unsupervised machine learning models trained on each metric's own history automatically flag anomalies without manual threshold configuration, and Netdata Cloud adds centralized dashboards, log management, and AI-assisted troubleshooting sessions across an organization's entire monitored fleet.
Netdata follows a freemium model. The open-source Agent is always free to self-host with no node limits, and Netdata Cloud's Community plan is free for up to 5 connected nodes and 1 custom dashboard under non-commercial use.
Paid Netdata Cloud tiers start with Homelab at 90 dollars per year for unlimited personal, non-commercial nodes, followed by Business at 4.50 dollars per node per month billed annually (6 dollars per node per month billed monthly) with unlimited metrics, logs, users, and retention, and Enterprise On-Premise with custom pricing starting at 200 node licenses.
Yes, the core Netdata open-source Agent is free to self-host, and Netdata Cloud offers a free Community plan for up to 5 connected nodes.
Netdata was created by Costa Tsaousis, who built the original monitoring agent out of frustration with existing monitoring tools.
Paid plans start with Homelab at 90 dollars per year for unlimited personal, non-commercial nodes, and Business at 4.50 dollars per node per month billed annually (6 dollars per node per month billed monthly).
Netdata trains lightweight unsupervised machine learning models on each individual metric's history to automatically flag unusual behavior without manual thresholds.
Netdata has raised roughly 34.9 million dollars in total funding, including a 17 million dollar Series A round led by Bain Capital Ventures and a later extension led by Bessemer Venture Partners.
Netdata is headquartered in San Francisco, California.
Yes, Netdata monitors servers, containers, Kubernetes, networks, and cloud infrastructure in real time.
