Sematext Tracing vs SigNoz

Sematext Tracing is an OpenTelemetry-based distributed tracing service for monitoring and troubleshooting microservices and distributed systems. It accepts OTLP over HTTP or gRPC and works with OpenTelemetry Collectors, Jaeger, Zipkin, and compatible instrumentation. Users can filter traces by service, operation, latency, errors, or custom attributes, then inspect waterfalls and spans. Error rates, error types, and stack traces appear within the related request trace, while a Service Map depicts application dependencies and communication patterns. Performance views include latency breakdowns, P50/P95/P99 percentiles, RED metrics, and database query insights. Head-based sampling can retain errors and high-latency requests while sampling normal traffic at lower rates. Alerts can use latency thresholds, error rates, or custom span attributes. The product lists support for languages and frameworks including Java, Python, Go, .NET, Swift, Android, Spring, Django, Rails, React, Vue, and Svelte. Deployment options include Kubernetes, Docker, containers, or bare metal. Pricing is based on spans; the listed starting price is $17.10/mo (annual), and a 14-day trial is available without a credit card. There is no free plan.

SigNoz is an open-source observability tool for monitoring applications and infrastructure. It brings logs, metrics, traces, and exceptions together with alerting and separate explorers for Trace, Logs, and Metrics. The OpenTelemetry-native design does not require proprietary agents. A Query Builder supports aggregations, filters, and formulas across signal types, while alerts can detect thresholds, anomalies, and Apdex conditions. Users can create dashboards from metrics, logs, and traces. APM charts cover p99 latency, error rate, Apdex, and operations per second, alongside database and external-call monitoring. Distributed tracing uses flamegraph and Gantt-chart views to follow requests across services. SigNoz stores telemetry in ClickHouse with hot and cold tiers. It can run in the cloud or be self-hosted using Docker, Docker Swarm, or Kubernetes. Cloud provides 30-day access to all features for new users; the self-hosted Community option is free but requires users to manage infrastructure, storage, scaling, upgrades, and backups.
