The short version

  • Only Jaeger has a free tier, so it costs nothing to try first.
  • Each has a real cost: Jaeger tracing is only as good as the instrumentation, and partial instrumentation produces misleading gaps; WarpBuild per-minute pricing requires tracking usage to estimate monthly costs
  • They diverge on capability: Jaeger covers Distributed trace search, WarpBuild covers Optimized runner infrastructure.
  • Prices and features above were last checked on 29 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

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

WarpBuild

  • Per-minute pricing requires tracking usage to estimate monthly costs
  • Large configuration runners (32 vCPU) expensive at $0.064/min
  • macOS M4 Pro 12-core at $0.16/min is highest-cost option
  • BYOC option requires cloud setup by customer

Questions people ask

Is Jaeger or WarpBuild better?
Neither clearly leads. Jaeger starts at Free and WarpBuild at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Jaeger or WarpBuild?
Jaeger has a free tier; the other does not. Paid plans start at Free for Jaeger and On request for WarpBuild.
Does Jaeger or WarpBuild run on more platforms?
Jaeger runs on Linux, Kubernetes, Docker. WarpBuild runs on GitHub Actions, Linux, Windows, macOS, Cloud.
Can I use Jaeger for free?
Yes. Jaeger has a free tier, so you can try it without paying. WarpBuild starts at On request.
What is Jaeger best used for?
Jaeger is most often used 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. Of those, finding which service in a request path causes the latency and understanding real service dependencies rather than the diagram on the wiki are not what WarpBuild is typically brought in for.
What can Jaeger do that WarpBuild cannot?
Jaeger covers Distributed trace search, Dependency graph, Adaptive sampling, Pluggable storage. WarpBuild covers Optimized runner infrastructure, Intelligent caching, Incremental builds, Multi-architecture support.

Answered from the vendors’ own pages

Jaeger: Is Jaeger free?

Yes, open source and CNCF-graduated. Costs are the storage backend you run.

WarpBuild: How much cheaper is WarpBuild compared to GitHub Actions?

WarpBuild offers approximately 50% cost savings compared to GitHub-hosted runners. For example, Linux x86-64 2vCPU/8GB costs $0.004/min with WarpBuild vs $0.008/min with GitHub Actions.

Source
Jaeger: Do I use Jaeger or OpenTelemetry?

Both, usually. Instrument with OpenTelemetry and use Jaeger to store and query the traces.

WarpBuild: What is BYOC and how does it differ from managed runners?

BYOC (Bring Your Own Cloud) allows customers to run WarpBuild on their own cloud infrastructure at $0.002/min. Managed runners use WarpBuild's cloud infrastructure. BYOC provides lower costs but requires customer setup.

Source
Jaeger: Does Jaeger handle metrics and logs?

No. It is a tracing system. Metrics and logs need Prometheus, Loki or an equivalent.

WarpBuild: Does WarpBuild support ARM64 runners?

Yes, WarpBuild offers ARM64 runners at lower costs than x86-64. Linux ARM64 starts at $0.003/min for 2vCPU/8GB configuration.
