The Best Datadog Alternatives in 2026
The best Datadog alternative for small fleets is Beszel, self-hosted on InstaPods for $3/mo flat with unlimited hosts. Datadog Infrastructure is $15 per host per month, so ten servers is $150/mo. Netdata, Zabbix and Grafana Cloud cover the heavier end.

The 6 best Datadog alternatives, ranked
| # | Tool | Price | Self-hosted | Best for |
|---|---|---|---|---|
| 1 | Beszel (self-hosted on InstaPods) Our pick | $3/mo flat, unlimited hosts | Yes (open source, MIT) | Homelabs and small fleets that want CPU, memory, disk and Docker stats with alerts, and nothing else |
| 2 | Netdata | Free for up to 5 nodes. Business $4.50/node/mo. Homelab $90/yr | Yes (open source agent) | Per-second resolution and the most detailed out-of-the-box dashboards |
| 3 | Zabbix | Free and open source (GPL) | Yes (open source) | Enterprise-grade monitoring of network gear, SNMP devices and mixed estates |
| 4 | Grafana Cloud | Free for 10,000 series, then $19/mo plus $6.50 per 1,000 series | Yes (Grafana + Prometheus, self-managed) | Teams that want dashboards, metrics, logs and traces in one stack |
| 5 | New Relic | Free for 100 GB/mo, then $0.40/GB ingested. Logs $0.30/GB | No | Full APM and tracing with a genuinely usable free tier |
| 6 | Datadog | $15/host/mo Infrastructure, rising to $23/host/mo on higher tiers | No | Large estates that need APM, logs, RUM, security and 800-plus integrations in one pane |
The catch with each one
Every tool here has a real downside, including ours. These are them.
Beszel (self-hosted on InstaPods)
No APM, no distributed tracing, no log aggregation. It is server monitoring, not observability.
Netdata
The agent uses 200-500 MB of RAM per node, which is a lot on small servers, and per-node pricing returns above 5 nodes.
Zabbix
The setup and learning curve are the steepest here. Plan days, not an afternoon, and budget for ongoing upkeep.
Grafana Cloud
Priced per active metric series, which is hard to predict. Self-hosting means running Prometheus, Grafana and the exporters yourself.
New Relic
Priced on data ingestion, so a chatty service or a debug-logging incident can produce a surprising invoice.
Datadog
Per-host pricing plus separate meters for logs, APM and RUM. Ten hosts is $150/mo on the cheapest tier before add-ons.
Why people look for Datadog alternatives
Datadog charges per host. Infrastructure is $15 per host per month, rising to $23 on higher tiers, and logs, APM and RUM are metered separately on top. Ten servers on the cheapest tier is $150/mo, or $1,800 a year, before you have ingested a single log line.
For a homelab or a small production fleet, that is wildly out of proportion to the question being asked, which is usually: is the box up, is the disk filling, is memory climbing, and did anything just die. Beszel answers exactly that. It is MIT-licensed, gives you CPU, memory, disk, network and per-Docker-service stats with historical charts and alerting, and the agent is small enough to sit on a Raspberry Pi.
On InstaPods, Beszel runs on the Launch plan for $3/mo flat (1 vCPU, 512 MB RAM, 10 GB disk) and monitors as many hosts as you point at it. Ten hosts is $3/mo. Fifty hosts is $3/mo. That is $36 a year against Datadog’s $1,800 for the same ten machines.
Be clear about the ceiling. Beszel has no APM, no distributed tracing and no log aggregation. If you need to know which database query made a request slow, you need Datadog, New Relic or a Grafana stack, and Beszel is not in that conversation.
Which one should you pick?
Three situations, three different right answers.
You want to know if your servers are healthy
Beszel on InstaPods. $3/mo flat for unlimited hosts, five-minute setup, and alerts that reach you before your users do.
You want deep per-second metrics
Netdata. Free up to 5 nodes and unmatched detail out of the box, as long as you can spare 200-500 MB of RAM per node.
You need APM, tracing and logs
Datadog, New Relic or a self-managed Grafana and Prometheus stack. No lightweight monitor replaces application performance monitoring.
Frequently asked questions
What is the cheapest Datadog alternative?
Self-hosted Beszel at $3/mo flat on InstaPods, with no per-host fee. Zabbix is free as software but you supply the server and the setup time. Netdata is free for up to 5 nodes, then $4.50 per node per month.
How much does Datadog cost per host?
Datadog Infrastructure is $15 per host per month, and higher tiers run to $23 per host per month. Logs, APM and RUM are metered separately. Ten hosts on the Infrastructure tier is $150/mo. Prices verified 2026-08-06.
Is there an open-source Datadog alternative?
Several. Beszel for lightweight server and Docker monitoring, Netdata for high-resolution metrics, Zabbix for enterprise and network monitoring, and Prometheus with Grafana for a full metrics stack. Beszel is the one InstaPods deploys in a click for $3/mo.
Does Beszel do application performance monitoring?
No. Beszel monitors systems: CPU, memory, disk, network, temperature and per-Docker-service stats, with history and alerts. It has no APM, no distributed tracing and no log aggregation. For those you want Datadog, New Relic or a Grafana stack.
