Jaeger vs Sematext Tracing

Jaeger is a free, open-source distributed tracing platform for monitoring complex systems and investigating performance problems. It helps teams locate bottlenecks, examine root causes, and map dependencies between services. Jaeger receives OpenTelemetry Protocol data and accepts Zipkin spans over HTTP in Thrift, JSON v1/v2, and Protobuf formats. Its UI includes System Architecture and Deep Dependency Graph views, while Service Performance Monitoring turns traces into aggregate metrics and time-series charts. Sampling supports head-based configurations, including centralized static or adaptive settings, and tail-based sampling. Cassandra, Elasticsearch, and OpenSearch are supported distributed storage backends; ClickHouse is experimental behind a feature gate. Jaeger v2 ships as binaries and container images, with an all-in-one mode using transient in-memory storage. It is self-hosted, so infrastructure determines capacity and scale. Jaeger v1 reached end of life on December 31, 2025.

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.
