Datadog
Datadog: Commercial APM that bundles tracing with metrics and logs, removing the storage operations Jaeger leaves you
Overview
What Jaeger does
Jaeger is an open-source distributed tracing system, originally built at Uber and now a graduated CNCF project. It answers the question monitoring dashboards cannot in a microservice architecture: a request took four seconds, and which of the fourteen services it touched was responsible. It collects spans from instrumented services, stores them, and provides a UI for searching traces and viewing them as flame graphs. Modern deployments generally instrument with OpenTelemetry and use Jaeger as the storage and query backend.
What people use it for
- Finding which service in a request path causes the latency
- Understanding real service dependencies rather than the diagram on the wiki
- Debugging failures that only appear under production traffic patterns

The honest half
Where it falls short
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Jaeger.
- Tracing is only as good as the instrumentation, and partial instrumentation produces misleading gaps
- Storage is the real operational cost: high-volume tracing on Elasticsearch or Cassandra is a cluster to run and pay for
- Traces alone, without correlated metrics and logs, leave you switching between tools during an incident
Cross-shopped
What people choose instead of Jaeger
Each pairing was judged by two reviewers asking whether a buyer would genuinely weigh the two against each other. The ones that failed were deleted rather than published.

Questions people ask
Each answer names the page it came from, so you can check it rather than take our word for it.
Is Jaeger free?
Yes, open source and CNCF-graduated. Costs are the storage backend you run.
Do I use Jaeger or OpenTelemetry?
Both, usually. Instrument with OpenTelemetry and use Jaeger to store and query the traces.
Does Jaeger handle metrics and logs?
No. It is a tracing system. Metrics and logs need Prometheus, Loki or an equivalent.

Softwr does not host reviews and shows no star rating for Jaeger, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it.
