SigNoz is an open-source observability tool that unifies logs, metrics, traces, and alerts in one platform. It helps teams monitor and troubleshoot application performance with flexible deployment and powerful ingestion.
SigNoz is an open-source observability platform that brings logs, metrics, traces, and alerts together in a single, unified interface. Built on OpenTelemetry standards and powered by ClickHouse for fast data ingestion, it positions itself as a cost-effective alternative to proprietary tools like Datadog and New Relic. The platform is designed for teams that want full control over their telemetry data without vendor lock-in, offering both cloud-hosted and self-hosted deployment options.
The core strength of SigNoz lies in its native support for OpenTelemetry, the industry-standard telemetry framework. This allows teams to instrument their applications once and collect all three pillars of observability -- traces, metrics, and logs -- without needing separate agents or proprietary SDKs. The platform excels at distributed tracing, enabling developers to follow user requests across microservices and pinpoint performance bottlenecks. It also includes log management at scale, custom dashboards, and a flexible alerting system that integrates with common notification channels like Slack, PagerDuty, and email.
SigNoz has recently expanded into LLM/AI observability, allowing teams to monitor calls to large language models, track token usage, and analyze performance of AI-powered features. The platform also offers agent-native observability through a Model Context Protocol (MCP) server, which brings telemetry data directly into coding assistants like Cursor and Claude. This makes it particularly useful for teams building and debugging AI applications.
Pricing is transparent and usage-based. The Community Edition is free and open-source, ideal for teams willing to self-host. The Teams Cloud plan starts at $49 per month with additional usage costs of $0.30 per GB for logs and $0.10 per million metric samples. Enterprise plans start at $4,000 per month and include dedicated environments, HIPAA compliance, and SLA support. A Startup Program offers 50% off for early-stage companies. Compared to Datadog, users report up to 80% cost savings.
SigNoz is best suited for developers, SREs, and platform teams who want a modern, open-source observability stack without the complexity of stitching together multiple tools. It works well for startups, scale-ups, and enterprises alike, especially those already using or adopting OpenTelemetry. The learning curve is moderate -- setup requires adding instrumentation to applications, but the documentation and community support are strong.
Overall, SigNoz is a compelling choice for any organization looking to reduce observability costs while maintaining high performance and flexibility. Its commitment to open standards, active community (25k+ GitHub stars), and continuous feature development make it a serious contender in the observability space. For teams tired of proprietary pricing and vendor lock-in, SigNoz offers a refreshing, capable alternative.
