SigNoz

SigNoz is an open-source observability platform that unifies distributed tracing, metrics, logs, dashboards, alerts, and LLM observability in a single OpenTelemetry-native system, positioned as an open-source alternative to Datadog and New Relic. The project has accumulated 25,000-plus GitHub stars, 140-plus contributors, 4,500-plus community members, and 10 million-plus open-source downloads. The ingestion engine handles over 10 terabytes of telemetry data per day with proven production scale, using ClickHouse as the columnar datastore, the same engine powering Uber and Cloudflare observability. Customers include NetApp, Samsung, Comcast, Salesforce, Freo, Formance, and GoKiwi. At Outplay, Tech Lead Vijaya Perumal optimized all top endpoints and improved backend API response times by 35 percent. At Convoy, Founder and CEO Subomi Oluwalana used OpenTelemetry traces to discover that the database driver was not using connection pooling despite documentation claims. The 2026 Agent Native Observability initiative connects SigNoz to coding agents including Claude Code and Cursor, enabling natural-language observability queries, end-to-end debugging from alert to root cause to fix, and team knowledge codification via skills.md files in GitHub repositories. The Noz AI teammate provides out-of-the-box observability assistance. Deployment options include SigNoz Cloud in US, EU, and India regions, self-hosted open source, and on-premises managed by the SigNoz team. The platform is HIPAA and SOC 2 compliant. Pricing is usage-based with no user-based or host-based charges.
