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.; UptimeRobot free plan is limited to a 5 minute check interval; sub-minute checking (60 seconds) requires the paid Solo plan and faster intervals (30 or 15 seconds) require Team or Scale

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.

UptimeRobot

  • Free plan is limited to a 5 minute check interval; sub-minute checking (60 seconds) requires the paid Solo plan and faster intervals (30 or 15 seconds) require Team or Scale
  • Team plan includes only 3 seats; additional seats are not covered in the base $41/$35 per month price
  • Enterprise pricing and faster-than-15-second intervals are custom and require contacting sales

Questions people ask

Is Jenkins or UptimeRobot better?
Neither clearly leads. Jenkins starts at Free and UptimeRobot at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Jenkins or UptimeRobot?
Jenkins starts at Free and UptimeRobot at Free.
Does Jenkins or UptimeRobot run on more platforms?
Jenkins runs on Linux, Windows, Macos, Docker. UptimeRobot runs on Web.
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 UptimeRobot is typically brought in for.
What can Jenkins do that UptimeRobot cannot?
Jenkins covers Plugin ecosystem, Distributed agents, Declarative and scripted pipelines, Shared libraries.

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.

UptimeRobot: What is UptimeRobot's refund policy?

UptimeRobot offers a 14-day money-back guarantee for new subscriptions and upgrades.

Source
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.

UptimeRobot: Can I cancel my subscription anytime?

Yes. You can cancel at any time by turning off auto-renewal. Your subscription remains active until the end of the current billing cycle.

Source
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.

UptimeRobot: What payment methods does UptimeRobot accept?

UptimeRobot accepts major credit and debit cards (Visa, Maestro, MasterCard, Discover, Diners Club, American Express) as well as wire transfers.

Source
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.

UptimeRobot: What are the monitor limits by plan?

Free: 50 monitors | Solo: 50 | Team: 100 | Scale: 200-500

Source
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.
