Netdata offers deep, real-time metrics with AI-powered anomaly detection. But it uses 200MB+ RAM per node and limits its free cloud tier to 5 nodes. Beszel gives you the essential server and Docker metrics with <10MB RAM usage for $3/mo.
Beszel is a lightweight server monitor that uses under 10MB RAM and focuses on essential metrics like CPU, memory, disk, network, and Docker stats. Netdata is a feature-rich observability platform with 1-second resolution, AI anomaly detection, and thousands of metrics. Choose Beszel for simple homelab and Docker monitoring. Choose Netdata if you need deep, real-time diagnostics across complex infrastructure.

Limitations that push you toward self-hosting.
Netdata agents use 200-500MB RAM per node. On a Raspberry Pi or small VPS, that is a significant portion of your available memory just for monitoring.
Netdata Cloud's free tier limits you to 5 nodes. Monitoring more requires the Pro plan at $5/node/month, which adds up quickly across a homelab.
Netdata shows 2,000+ charts by default. For most users who just want to see CPU, memory, and disk, this is information overload that makes it harder to find what matters.
While the agent auto-detects many services, customizing alerts, retention, and dashboards requires editing YAML config files and understanding Netdata's plugin system.
What you get when you own your infrastructure.
Beszel agent uses under 10MB RAM. Run it on Raspberry Pis, cheap VPS instances, or resource-constrained servers without impacting your workloads.
See exactly what matters: CPU, memory, disk, network, and Docker stats. No 2,000-chart wall to scroll through. Click a server, see its health.
Add as many agents as you want. Whether you monitor 1 server or 50, the hosting cost for the Beszel hub stays at $3/mo on InstaPods.
Deploy the hub, install agents with a single command, and monitoring starts immediately. No YAML files, no plugin config, no dashboard setup.
Monitoring 10 servers (mix of VPS and homelab) with Docker containers.
Beszel is the most popular lightweight alternative to Netdata. It uses under 10MB RAM per agent (vs Netdata's 200-500MB), provides essential server and Docker metrics, and requires zero configuration. Other lightweight options include Glances and htop, though neither offers a web dashboard with historical data like Beszel does.
Netdata is worth it if you need deep, real-time observability with AI anomaly detection across complex infrastructure. The free tier works well for up to 5 nodes. But for most homelab users and small teams who primarily need CPU, memory, disk, and Docker stats, Beszel provides everything you need with a fraction of the resource overhead.
For most homelab and small server setups, yes. Beszel covers the metrics that 90% of users actually check: CPU, memory, disk, network, and Docker container stats. If you rely on Netdata's AI anomaly detection, 1-second resolution, or its 2,000+ metric collectors, you'll want to keep Netdata.
Netdata agents typically use 200-500MB RAM per node, which is significant on small servers. The Netdata team has worked on reducing this, but the extensive metric collection and real-time processing inherently requires more memory. Beszel's agent uses under 10MB by comparison.
Deploy Beszel on InstaPods and stop paying for features that should be free.
