overview

What is SigNoz?

SigNoz is an observability tool developed by SigNoz that enables developers and DevOps/SRE teams to gain real-time visibility into their applications and infrastructure. It unifies logs, metrics, distributed traces, and exceptions into a single interface, aiming to simplify application performance monitoring (APM) and troubleshooting. The platform is OpenTelemetry-native, ensuring vendor-neutral data collection, and utilizes ClickHouse for high-performance data storage and querying. SigNoz provides deep code-level tracing to identify performance bottlenecks and errors, facilitating comprehensive root cause analysis. It also features an integrated AI Teammate, 'Noz', designed to assist with natural language querying and incident investigation workflows.

how to use

How to Use SigNoz

SigNoz can be deployed as a self-hosted solution or utilized through its cloud offering. The initial setup involves instrumenting applications with OpenTelemetry to send telemetry data to SigNoz.

  • 1Deploy SigNoz: Choose between self-hosting the Community Edition or signing up for SigNoz Cloud.
  • 2Instrument Applications: Integrate OpenTelemetry SDKs into your services to collect logs, metrics, and traces.
  • 3Configure Data Export: Direct OpenTelemetry collectors to send telemetry data to your SigNoz instance.
  • 4Explore Dashboards: Utilize pre-built or custom dashboards to visualize application and infrastructure performance metrics.
  • 5Analyze Traces and Logs: Use Flamegraphs, Gantt Charts, and the log explorer to drill down into specific requests and events for root cause analysis.
  • 6Set Up Alerts: Configure alerts based on metrics, logs, or traces to receive notifications for critical incidents.

pricing

SigNoz Pricing & Plans

SigNoz operates on a freemium model, offering both a free, self-hosted Community Edition and a usage-based cloud offering. The Community Edition provides full functionality without data caps or license fees, requiring users to manage their own infrastructure. SigNoz Cloud offers a free account with 30 days of unlimited access, after which pricing is based on data ingestion and retention, aiming for predictable costs without per-host or per-user charges.

  • Community Edition: Free, self-hosted, open-source with no data caps.
  • Cloud Offering: Usage-based pricing, includes a free account with 30 days of unlimited access.

Pros

  • +Open-source and OpenTelemetry-native, providing vendor-neutral instrumentation and avoiding lock-in.
  • +Unifies logs, metrics, and traces into a single platform, simplifying context switching during incident resolution.
  • +Cost-effective with a free self-hosted Community Edition and usage-based cloud pricing.
  • +Utilizes ClickHouse for high-performance storage, enabling fast full-text log search and efficient aggregation queries.
  • +Includes an integrated AI Teammate (Noz) for natural language querying and incident investigation.
  • +Provides robust features for APM, distributed tracing with Flamegraphs, and customizable dashboards.

Cons

  • −Self-hosting the Community Edition requires operational effort, particularly for managing and scaling ClickHouse.
  • −Some advanced features, including the AI assistant, are still maturing compared to established offerings.
  • −The learning curve for self-hosting and optimizing ClickHouse can be significant for teams without prior experience.
  • −While unified, the breadth of integrations and specialized features might be less extensive than highly modular, multi-tool stacks for specific niche use cases.

SigNoz vs Competitors

SigNoz differentiates itself in the observability market through its OpenTelemetry-native architecture, unified data store, and integrated AI capabilities, contrasting with both modular open-source stacks and proprietary solutions.

1
Grafana (with Prometheus, Loki, Tempo)On Stork

A modular, battle-tested stack of open-source tools, each specialized for metrics (Prometheus), logs (Loki), or traces (Tempo), unified by Grafana for visualization.

SigNoz offers a unified data store (ClickHouse) for all signals, aiming for simpler setup and correlation. The Grafana stack requires integrating and managing multiple separate components, which can increase operational overhead and learning curve, and it does not include an integrated AI Teammate like SigNoz's Noz.

2
OpenObserveOn Stork

A single-binary, OpenTelemetry-native observability platform that unifies logs, metrics, and traces, designed for cost-effective storage on object storage.

OpenObserve aims for lower storage costs and simpler operation with a single binary and object storage backend. SigNoz uses ClickHouse and provides an integrated AI Teammate for natural language querying and incident investigation, which OpenObserve does not currently offer.

3
Elastic Observability (ELK Stack)↗

A powerful, search-engine-backed platform for logs, metrics, and traces, offering deep log analytics and full-text search capabilities.

SigNoz is OpenTelemetry-native and uses ClickHouse for a unified data store, aiming for easier correlation and includes an AI Teammate. The ELK stack, while robust for log management, can be complex to set up and scale, and its operational overhead for self-hosting can be higher than SigNoz's ClickHouse, and it lacks a native AI assistant.

4
Uptrace↗

A scalable observability platform built on OpenTelemetry, providing monitoring for traces, metrics, and logs with a focus on being lightweight and cost-effective.

Uptrace offers a lightweight and cost-effective solution with native OpenTelemetry support. SigNoz provides a more comprehensive, full-stack platform with an integrated AI Teammate for incident investigation, which Uptrace does not emphasize.
