The short version

  • Each has a real cost: Jenkins the controller is stateful and, in the open source distribution, has no high availability: build history, configuration and plugin state live on one filesystem, so every plugin upgrade and core update is downtime for every team using it, and a controller disk failure is a restore-from-backup event.; OpenTelemetry genuinely complex to adopt: collectors, pipelines, samplers and exporters are a system to run in their own right
  • They diverge on capability: Jenkins covers Plugin ecosystem, OpenTelemetry covers Vendor-neutral SDKs.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

Jenkins

  • The controller is stateful and, in the open source distribution, has no high availability: build history, configuration and plugin state live on one filesystem, so every plugin upgrade and core update is downtime for every team using it, and a controller disk failure is a restore-from-backup event.
  • Capability comes from around 1,900 community plugins of very uneven maintenance, and the Jenkins security team regularly publishes advisories for plugins whose maintainer has gone; in some cases the advisory itself states that no fix is available and the only remedy is to stop using it.
  • Plugin upgrades are coupled: one plugin can require a newer core or a newer version of another plugin, so applying a single security fix cascades into a coordinated upgrade of a dozen components on a timetable you did not choose.
  • Pipelines are Groovy running under a sandbox and a continuation-passing-style transformation, so ordinary Groovy constructs sometimes fail in non-obvious ways, and the debugging skill you build transfers to no other CI system.
  • It is free to licence and expensive to run: somebody must own the controller, the agents, the Java version, the credentials store and the plugin upgrade cycle, and that recurring staff cost is the usual reason organisations move to hosted CI even when Jenkins works.
  • Leaving is costly by construction, because shared libraries, plugin-specific pipeline steps and accumulated freestyle jobs have no mechanical translation into GitHub Actions or GitLab CI, so the migration is a rewrite whose price grows every year you defer it.

OpenTelemetry

  • Genuinely complex to adopt: collectors, pipelines, samplers and exporters are a system to run in their own right
  • Language SDKs mature at different rates, so a polyglot estate gets uneven support
  • It produces and moves telemetry but does not store or visualise it, so a backend is still required and still billed

Questions people ask

Is Jenkins or OpenTelemetry better?
Neither clearly leads. Jenkins starts at Free and OpenTelemetry at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Jenkins or OpenTelemetry?
Jenkins starts at Free and OpenTelemetry at Free.
Does Jenkins or OpenTelemetry run on more platforms?
Jenkins runs on Linux, Windows, Macos, Docker. OpenTelemetry runs on Linux, macOS, Windows, Kubernetes, Docker.
Can I use Jenkins for free?
Both have a free tier, so you can try either at no cost before committing.
What is Jenkins best used for?
Jenkins is most often used for builds that must touch physical hardware, such as embedded devices, test rigs or signing modules attached to a specific machine, air-gapped or heavily regulated environments where a hosted ci runner cannot be used at all, toolchains that hosted ci does not support, including node-locked commercial licences for eda, cad or simulation software, organisations with years of existing jenkins pipelines where the migration cost currently outweighs the operational cost of staying. Of those, builds that must touch physical hardware, such as embedded devices, test rigs or signing modules attached to a specific machine and air-gapped or heavily regulated environments where a hosted ci runner cannot be used at all are not what OpenTelemetry is typically brought in for.
What can Jenkins do that OpenTelemetry cannot?
Jenkins covers Plugin ecosystem, Distributed agents, Declarative and scripted pipelines, Shared libraries. OpenTelemetry covers Vendor-neutral SDKs, Collector, Three signals, Auto-instrumentation.

Answered from the vendors’ own pages

Jenkins: Why choose Jenkins over GitHub Actions or GitLab CI?

When the build needs something hosted runners cannot give you: physical hardware, an air-gapped network, a node-locked commercial tool licence, or an unusual platform. If none of those apply, hosted CI is usually less work to own.

OpenTelemetry: Is OpenTelemetry free?

Yes, open source under the CNCF. What you pay for is the backend you export to.

Jenkins: Can Jenkins run in high availability?

Not in the open source distribution, which runs a single active controller. High availability and active-active controllers are features of CloudBees' commercial products. Open source deployments mitigate it with fast restores and, sometimes, multiple independent controllers.

OpenTelemetry: Does OpenTelemetry replace Datadog or Grafana?

No. It replaces their proprietary agents and instrumentation libraries. You still need a backend to store and query the data.

Jenkins: How risky are the plugins?

This is the main operational risk. Many plugins have a single volunteer maintainer, and Jenkins publishes security advisories for unmaintained plugins where no fix exists. Auditing which plugins you depend on and who maintains them should be a periodic task, not a one-off.

OpenTelemetry: Why adopt a vendor-neutral standard?

Because instrumentation is the expensive part. Once code emits OTel, changing observability vendor is a collector config change instead of re-instrumenting every service.

Jenkins: Do I need to know Groovy?

For declarative pipelines you can go a long way without it. Anything involving shared libraries, conditional logic or custom steps is Groovy, and it runs in a sandboxed, transformed environment where standard Groovy idioms sometimes behave unexpectedly.

Jenkins: What does it cost?

The software is free under the MIT licence. The cost is infrastructure and staff time to run controllers, agents and upgrades, plus a CloudBees subscription if you want high availability, support or centralised management of many controllers.
