Company profile

researched Aug 2026

SigNoz is an observability platform that consolidates logs, metrics, traces, dashboards, alerts and error tracking into a single tool, positioning itself as an open-source alternative to Datadog and New Relic. Core capabilities include application performance monitoring, distributed tracing to follow user requests across services, log ingestion, search and analysis, infrastructure and custom metrics with configurable dashboards, exception tracking, alerting to user-chosen notification channels, and LLM/AI observability for monitoring LLM calls, performance and usage in AI applications. Data can be ingested from more than 50 sources.

The product is offered in two deployment modes: SigNoz Cloud, a managed service with regional data residency options in the US, EU and India, and Self-Hosted SigNoz for teams that need to run the stack on their own infrastructure; managed enterprise deployment options are also referenced. Enterprise features include SSO and SAML support, query API keys and additional security and compliance controls. More recently the company has added agent-native observability, which connects SigNoz Cloud to coding agents such as Claude Code and Cursor, integrations with Kubernetes, Git, Jira and cloud provider CLIs for root-cause workflows, natural-language interaction for tasks like building dashboards, and an in-product AI teammate called Noz. Teams can codify debugging practices in a shared skills.md file.
