A Netdata alternative for people who want a control room, not a microscope

Netdata is a microscope: per-second data and thousands of charts per box, free and open source. PulseNode is a control room: one hosted page over the fleet. Where Netdata is the better pick, this page says so.

PulseNode · updated July 2026

If you're searching for a Netdata alternative, price is probably not the reason. Netdata costs nothing, the agent is open source under GPLv3+, and it collects thousands of metrics per node, every second. The problem is different: ten servers means ten walls of charts, and the question most mornings is just whether everything is fine.

This page is for people running roughly 5 to 20 VPSes who want that fleet answer on one hosted page. Up front: PulseNode is young, closed source, built by one person, and paid. Netdata is none of those things. If that already decides it, keep Netdata.

The short answer

What Netdata does brilliantly

Credit first. Netdata collects and processes metrics every second, with about one second from collection to chart. A fresh install discovers what's running and instruments it without configuration; Netdata's own example is a small AWS Lightsail instance producing 2,945 metrics every second. Install is a one-line kickstart script, and there are 800+ collectors. The machine learning is real engineering: each agent trains unsupervised k-means models locally, 18 models per metric, and flags an anomaly only when all of them agree. Training data never leaves the box.

Storage is local and tiered: per-second data for 14 days, per-minute for 3 months, per-hour for 2 years by default. For a fleet view with no SaaS at all, a self-hosted Netdata Parent receives streams from your nodes, stores their history, serves dashboards, and sends alerts for all of them. All of it is free. If that reads like exactly what you want, install Netdata and close this tab.

So why do people search for a Netdata alternative?

Thousands of metrics per node is a microscope, not a status board

The metric count is deliberate, and at 3am on one misbehaving box it's exactly what you want. The rest of the time it's surface area. Thousands of charts answer "what is wrong with this server" superbly and "are my nine servers fine" slowly. Most days you're asking the second question.

A fleet view still means Cloud or a Parent you run

Netdata's unit of thought is the node; the multi-node overview is something you assemble on top, through Netdata Cloud or a self-hosted Parent. Both work well. But a Parent is another Netdata that you size, secure, back up, and keep updated, and Cloud past its 5 free nodes is a per-node subscription. Some people want neither the chore nor the meter. PulseNode's only unit of thought is the fleet: every server on one page, sorted by whether it needs you.

The agent's footprint and the open port

Netdata publishes its own numbers: about 5% of one CPU core and around 150 MiB of RAM by default, under 1% and about 100 MiB with ML and alerts turned off. The part more people trip on is the port: every agent serves a local dashboard on 19999, listening by default by design, as Netdata's own blog explains. It's read-only and configurable, but on an internet-facing VPS it's one more thing to firewall. The PulseNode agent has no port at all; it pushes outbound and never listens.

PulseNode: a hosted multi-server Netdata alternative for small fleets

PulseNode is dashboard-first SaaS. One agent per server pushes metrics out over HTTPS about every 30 seconds, roughly 30 times coarser than Netdata, on purpose. The metrics: per-core CPU and load average, RAM and swap, disk per mount plus disk I/O throughput, network per interface, and uptime. Charts cover 1h, 6h, 24h, and 7d, with 14d and 30d on Pro.

Around the metrics sit the fleet views: every Docker container on every server (status, image, uptime), open TCP/UDP ports with the owning process, and external HTTP(S) checks with TLS expiry. The external checks are status-only: the dashboard shows up/down, latency, and days to expiry, and sends no notifications. If a failing check or an expiring cert needs to reach your phone, that isn't built yet.

Alerts that fit on an index card

Alert rules cover three metrics: CPU percent, RAM percent, and disk percent, where disk means the fullest mount on the box. A rule reads like cpu > 85% or disk > 90%. Rules have cooldowns (1 to 1440 minutes, default 15) and send a recovery notice when the value comes back down. Channels are email and Telegram; you connect Telegram in settings by pasting a chat ID, with no bot server to host. One alert you never write: when an agent stops pushing, PulseNode tells you. That agent-offline check is a built-in dead-man's switch and needs no rule once a channel is set. This is not zero configuration, just short configuration: you enter an address or a chat ID and write your thresholds.

An agent that can't be knocked on

The agent is a single static Go binary for Linux amd64 and arm64, installed with one command as a hardened systemd service. It pushes outbound over HTTPS about every 30 seconds, never listens on any port, and nothing ever connects to it.

Netdata vs PulseNode head-to-head

Sources: the Netdata GitHub README, Netdata Learn docs on storage, ML, and centralization, and the Netdata pricing page, checked July 2026 against Netdata v2.10.3. The PulseNode column reflects the product the same week.

Where PulseNode wins

• Nothing to operate. The dashboard runs on our infrastructure, separate from your servers, so when a box dies the agent-offline alert still goes out.
• One calm page over the whole fleet: a dozen metric families per server instead of thousands of charts.
• Alerts without plumbing: email and Telegram, cooldowns, recovery notices, and the dead-man's switch for silent agents.
• An outbound-only agent with no listening port, plus fleet-wide views Netdata doesn't aim at: ports by process, Docker status everywhere, TLS expiry at a glance (status-only).

What PulseNode does not do

So you aren't surprised after paying:

• Not open source, not self-hostable, and no public API or data export today. Your metrics live on our servers.
• No per-second data; metrics arrive about every 30 seconds.
• No anomaly detection; thresholds and the offline check are the whole story.
• History caps at 7 days on Hobby and 30 on Pro. A stock Netdata agent keeps per-hour data locally for 2 years.
• No alert when a Docker container stops; the container view is visibility only. External HTTP(S)/TLS checks send no notifications either.
• Linux only, amd64 and arm64. No Windows, macOS, or FreeBSD agent.
• It's a young product run by one founder. Support is personal and fast, but it's one inbox.

Pricing

Netdata first, since it sets the bar. The agent is free everywhere. Netdata Cloud's Community plan is free for up to 5 connected nodes with no commercial restriction. Homelab is $90/yr, unlimited nodes under fair use, non-commercial only. Business is $4.50 per node per month billed annually ($6 monthly) and counts only active nodes.

PulseNode has two flat plans, billed via Lemon Squeezy, VAT at checkout, cancel anytime:

• Hobby, €5/mo: up to 5 servers, 7-day history, live dashboard and charts, alert rules to email and Telegram, external HTTP(S) and TLS-expiry status checks.
• Pro, €15/mo: up to 20 servers, 30-day history, everything in Hobby, direct founder support.

At five nodes or fewer, Netdata costs you nothing. You'd pick PulseNode for the calm fleet page and for having nothing to operate, not to save money.

Get Hobby for €5/mo Get Pro for €15/mo

Who should stay on Netdata

Stay if you need per-second resolution, per-node forensics, or anomaly detection; if open source or self-hosting is a requirement; if you run more than 20 servers or non-Linux machines; if the budget is zero; or if you need an API and data export, which PulseNode doesn't offer. Weigh the vendors too: Netdata is a mature project with a large community, PulseNode is one founder and a young product. That difference is real.

Run both: the microscope and the control room

This isn't either/or. Netdata listens locally; the PulseNode agent pushes outbound and shares nothing with it. Keep Netdata where you want deep local forensics, and add the PulseNode agent everywhere (one command per server) for the everyday glance and the Telegram message when disk crosses 90%. Nothing to uninstall, and no Parent to build.
