Caddy vs Jenkins
A source-aware comparison of pricing, documented capabilities and workflow fit.
Short answer
- Price: both start at Free.
- How to start: both are free.
- Where they differ: on what we checked they match — both offer public api and open source / self-hostable.
These lines are generated from the pricing we track, not from a paid placement. How we score tools.
What Caddy is
What Caddy isCaddy is a web server that obtains and renews TLS certificates automatically, with a configuration file most people can read. Automatic HTTPS is not a module to enable but the default behaviour: point a domain at it and a valid certificate is issued and renewed without a cron job or a separate client. A Caddyfile for a reverse proxy with TLS is a few lines where the equivalent elsewhere runs to dozens, which is why it is a common choice for small deployments and internal services.
What Jenkins is
What Jenkins isJenkins is the long-standing open-source automation server. It runs anywhere, does almost anything through plugins, and costs nothing in licence fees; what it costs is maintenance. Choose it when you need to run builds on your own hardware, behind your own network rules, with no per-minute billing. Expect to own upgrades, plugin compatibility and the security of the controller yourself; that maintenance is the real price.

What Caddy is built to do
- Automatic HTTPS
- Certificates are issued and renewed by default, with no separate ACME client.
- Readable configuration
- A Caddyfile for TLS and reverse proxy fits in a few lines.
- Single binary
- Ships as one static binary with no runtime dependencies to install.
- Admin API
- Configuration can be changed at runtime over an HTTP API without a restart.
What Jenkins is built to do
- Plugin ecosystem
- Extends builds to almost any tool through a large plugin catalogue.
- Self-hosted controller
- Runs entirely on your own infrastructure with no per-minute billing.
- Pipeline as code
- Defines builds in a Jenkinsfile stored alongside the source.
Choose Caddy if
- Teams that want automatic HTTPS from a free, open source web server
- Self-hosters who prefer a single binary over a package plus certificate tooling
- Businesses that want paid private support, offered through sponsorship tiers
Skip Caddy if
- You require a contractual support SLA at a published price — sponsorship tiers are not priced on the site
- Your organisation forbids depending on sponsorship-funded projects
- You need a named commercial licence; the licence is not stated on the homepage
Choose Jenkins if
- Teams that want a free, MIT-licensed CI server they fully control, on their own hardware or Kubernetes
- Pipelines that depend on unusual tooling — Jenkins runs as a self-contained Java program with hundreds of plugins
- Organisations that want a stable baseline: LTS lines are cut every 12 weeks with fixes every 4 weeks
Skip Jenkins if
- You want a hosted service: Jenkins is self-hosted only, there is no vendor cloud
- Nobody on the team will own upgrades and plugin compatibility — that maintenance is the real cost
- You need vendor support and SLAs: the project is community-run under the Continuous Delivery Foundation

Caddy: pros & cons
- HTTPS configured correctly by default
- Configuration is short and legible
- Single binary, easy to deploy
- Smaller community than nginx
- Fewer third-party guides
- Some advanced setups need plugins
Jenkins: pros & cons
- Free and open source with no usage limits
- Enormous plugin ecosystem
- Runs entirely on your own infrastructure
- You maintain the server, the agents and the plugins
- Interface and defaults feel dated
- Plugin quality varies and updates can break builds
Our verdict on Caddy
The easiest path to good TLS defaults. nginx still wins on ecosystem and examples.
Our verdict on Jenkins
Still the right answer when control matters more than convenience. For most small teams a hosted CI is less work.
