What Is SigNoz?

SigNoz is an open-source observability platform designed to be an alternative to proprietary tools like DataDog and New Relic. Its core strength is its native support for OpenTelemetry (OTel), the open standard for collecting telemetry data. SigNoz aims to provide a single pane of glass for the three pillars of observability: metrics, traces, and logs.

Its primary focus is on Application Performance Monitoring (APM) and distributed tracing, helping developers understand the performance of their applications and services. By instrumenting code with OpenTelemetry, developers can send trace data to SigNoz to visualize request flows, identify bottlenecks, and debug errors. It uses a columnar database (ClickHouse) on the backend to store and query this high-cardinality data effectively.

Key Differences Between Netdata & SigNoz

While both are open-source observability tools, their core philosophies lead to significant differences in functionality, performance, and user experience.

Features & Functionality

The most significant difference lies in their primary focus and time-to-value.

Netdata is built for immediate, comprehensive infrastructure visibility. The moment you install the Netdata Agent, it automatically discovers hundreds of services and applications—from operating systems and containers to databases and web servers—and populates real-time dashboards. This zero-configuration approach means you get actionable insights in minutes. Its strength is providing an incredibly detailed, second-by-second view of system health and performance.

SigNoz is built for deep application-level analysis through OpenTelemetry. Its value is unlocked after you instrument your application code to emit traces. This process requires developer effort and a deep understanding of the codebase. While powerful for APM, it doesn’t provide the instant, out-of-the-box infrastructure context that Netdata does. You see what your code is doing, but you might miss the underlying system issue (like CPU saturation or network latency) that is causing the application problem.

In short, Netdata tells you what is happening across your entire stack right now, while SigNoz tells you why it’s happening inside your application code, but only after manual setup.

AI & Machine Learning

Netdata takes a proactive, automated approach to intelligence. Every Netdata Agent runs hundreds of unsupervised ML models directly on the node it’s monitoring. This “ML at the edge” approach allows it to learn the normal behavior of every single metric and detect anomalies in real-time without overwhelming a central system or requiring manual alert configuration. The new Agentic AI further enhances this by providing automated root cause analysis and a conversational interface to investigate issues.

SigNoz’s approach is more traditional. It relies on users to manually explore the relationships between metrics, traces, and logs to find the root cause. While it allows for setting alerts, it lacks the built-in, automated intelligence to proactively identify anomalies based on learned patterns. The analysis is largely a manual, reactive process driven by the engineer.

Pricing & Cost Management

This is a critical differentiator for teams concerned about budget predictability.

Netdata offers a simple and predictable per-node pricing model. You pay a flat fee for each system you monitor, regardless of how much data it generates. This model encourages you to collect as much granular data as you need without fearing a surprise bill. It makes budgeting straightforward and scalable.

SigNoz, like many APM-focused tools, has a pricing model based on data ingestion volume (e.g., GB of logs or traces per month) and retention period. This can become very expensive, very quickly. High-traffic applications, verbose logging, or complex microservice architectures can generate terabytes of data, leading to unpredictable and escalating costs. This pricing model often forces teams to sample data aggressively or limit what they monitor, creating blind spots.

Integrations & Compatibility

Netdata comes with over 300 integrations that work out-of-the-box. The agent auto-detects installed software and starts collecting metrics immediately. This includes operating systems, containers, databases, message queues, web servers, and much more.

SigNoz’s integration strategy is centered around OpenTelemetry. If a system or library can be instrumented with an OTel SDK, it can send data to SigNoz. This provides great flexibility for custom applications but means that for off-the-shelf software, you are reliant on the availability and quality of OTel collectors or instrumentation libraries.

Why Engineers Choose Netdata Over SigNoz

Engineers and IT leaders often choose Netdata as a SigNoz competitor or alternative because they need to solve problems now with minimal friction and maximum insight. Here’s why Netdata often comes out on top for full-stack observability:

1. Instant Time-to-Value: The most common pain point with complex observability tools is the lengthy setup. With SigNoz, you must invest significant time in instrumenting applications before you see value. With Netdata, you run a single command, and within minutes you have a rich, real-time view of your entire system. This immediate feedback loop is invaluable during an outage.

2. Unmatched Granularity for Real-Time Troubleshooting: When your service is down, every second counts. Metrics that are averaged or delayed by minutes are useless. Netdata’s per-second data granularity allows you to see issues as they happen, correlating spikes in CPU, disk I/O, and application metrics in real-time on a single screen. This level of detail is simply not the focus of APM tools like SigNoz.

3. Proactive Anomaly Detection without the Toil: Tired of writing and tuning alert rules? Netdata’s on-device ML automatically learns what’s normal for your systems and alerts you on what’s truly anomalous. It reduces alert fatigue and helps you catch “unknown unknowns” before they escalate into production incidents.

4. Predictable Costs and Superior Efficiency: The fear of runaway data ingestion costs is real. Netdata’s lightweight agent and per-node pricing model remove this anxiety. You can monitor everything, everywhere, at the highest possible resolution, without worrying about your observability bill spiraling out of control.
