A self-hosted automation server that can build almost anything, through a plugin ecosystem that is also its main liability.

The short version

  • Each has a real cost: Authelia depends on a reverse proxy: it is not a standalone identity provider; 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.
  • They diverge on capability: Authelia covers Reverse proxy integration, Jenkins covers Plugin ecosystem.
  • 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.

Authelia

  • Depends on a reverse proxy: it is not a standalone identity provider
  • Configuration is YAML-first with no administrative interface, so changes mean editing files
  • Not a full IAM: user management, provisioning and federation are limited compared with Keycloak
  • Scales poorly as an organisation-wide identity solution, which is not its target

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.

Answered from the vendors’ own pages

Authelia: Is Authelia free?

Yes, open source with no licence fee.

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.

Authelia: Does Authelia need a reverse proxy?

Yes. It integrates through forward authentication with Nginx, Traefik, Caddy or HAProxy rather than sitting in front of traffic itself.

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.

Authelia: Authelia or Keycloak?

Authelia is far lighter and aimed at protecting self-hosted services behind a proxy. Keycloak is a full identity and access management platform, and much more to run.

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.

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.
