The short version
- Only Jenkins has a free tier, so it costs nothing to try first.
- 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.; Zeta it competes against card processors with decades of production track record, and in card processing an outage is a public event, so a shorter operational history is a genuine risk factor rather than a technicality.
- They diverge on capability: Jenkins covers Plugin ecosystem, Zeta covers Tachyon card processing.
- Prices and features above were last checked on 1 September 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.
Zeta
- It competes against card processors with decades of production track record, and in card processing an outage is a public event, so a shorter operational history is a genuine risk factor rather than a technicality.
- Contracts are enterprise scale and quoted with volume minimums, which puts it out of reach of small issuers who would otherwise benefit most from modern tooling.
- A card portfolio migration runs twelve to twenty four months at minimum, during which the issuer runs two platforms and pays for both.
- Zeta is a processor rather than a licence holder, so network membership, BIN sponsorship and regulatory obligations remain entirely with the issuer.
- Public references for large live United States production volumes are fewer than the announcements imply, so diligence should insist on active account counts and uptime history rather than partnership press releases.

Questions people ask
- Is Jenkins or Zeta better?
- Neither clearly leads. Jenkins starts at Free and Zeta at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Jenkins or Zeta?
- Jenkins has a free tier; the other does not. Paid plans start at Free for Jenkins and On request for Zeta.
- Does Jenkins or Zeta run on more platforms?
- Jenkins runs on Linux, Windows, Macos, Docker. Zeta runs on Web, API, Cloud, iOS, Android.
- Can I use Jenkins for free?
- Yes. Jenkins has a free tier, so you can try it without paying. Zeta starts at On request.
- 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 Zeta is typically brought in for.
- What can Jenkins do that Zeta cannot?
- Jenkins covers Plugin ecosystem, Distributed agents, Declarative and scripted pipelines, Shared libraries. Zeta covers Tachyon card processing, Real time authorisation, Rewards and offers engine, Core banking modules.
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.
Zeta: Which Zeta is this?
The banking technology company founded by Bhavin Turakhia, which builds the Tachyon card processing and core banking platform. Not any similarly named payroll or accounting product.
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.
Zeta: What is its strongest use case?
United States credit card issuing and processing, where legacy platforms make product changes slow and expensive.
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.
Zeta: Does Zeta provide the BIN or licence?
No. It processes. Network membership, BIN sponsorship and regulatory obligations stay with the issuer.
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.
