Open source tracing and APM tools in 2026

Distributed tracing and application performance monitoring: follow a request across services and find where the time goes. This list has 8 tracing and APM tools. Of these, 8 are open source, 8 have a free plan and 8 can be self-hosted. Checked by hand on 30 September 2026.

  1. 1

    Apache SkyWalking

    APM for distributed systems from the Apache Software Foundation: agents and service mesh probes collect traces, metrics and logs and draw service topology maps.

    Free Open source (Apache-2.0) Self-hosted APMTracesMetricsLogs
  2. 2

    Grafana Tempo

    Distributed tracing backend that stores traces cheaply in object storage and accepts OpenTelemetry, Jaeger and Zipkin data.

    Free plan Open source (AGPL-3.0) Self-hosted TracesOpenTelemetry
  3. 3

    Jaeger

    CNCF distributed tracing platform for collecting, storing and exploring request traces across microservices; version 2 is built on the OpenTelemetry Collector.

    Free Open source (Apache-2.0) Self-hosted TracesOpenTelemetry
  4. 4

    Odigos

    Uses eBPF to add OpenTelemetry tracing to applications on Kubernetes without code changes and sends the data to any backend.

    Free plan Open source (Apache-2.0) Self-hosted TracesOpenTelemetryKubernetes
  5. 5

    OpenTelemetry eBPF Instrumentation (OBI)

    Zero-code eBPF instrumentation that produces traces and RED metrics for HTTP, gRPC, database and messaging calls from Linux processes. Started as Grafana Beyla and was donated to OpenTelemetry.

    Free Open source (Apache-2.0) Self-hosted OpenTelemetryTracesMetricsKubernetes
  6. 6

    Pinpoint

    APM for large Java and PHP systems that traces transactions across services and draws a server map of their calls.

    Free Open source (Apache-2.0) Self-hosted APMTraces
  7. 7

    Pixie

    Kubernetes observability that uses eBPF to capture service traffic, metrics and CPU profiles automatically; a CNCF sandbox project.

    Free Open source (Apache-2.0) Self-hosted KubernetesAPMMetrics
  8. 8

    Zipkin

    Distributed tracing system that collects timing data from instrumented services and shows where latency builds up across them.

    Free Open source (Apache-2.0) Self-hosted Traces
