The short version

  • Each has a real cost: CapRover since June 2026 one pseudonymous account wrote 97 of roughly 100 commits and the next human contributor wrote one, so there is no identifiable person or company to contract with, escalate to or hold responsible.; Icinga the free core has no vendor SLA, so production incidents are supported through community channels unless a paid support subscription is purchased
  • They diverge on capability: CapRover covers One-click applications, Icinga covers Forever Free core.
  • 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.

CapRover

  • Since June 2026 one pseudonymous account wrote 97 of roughly 100 commits and the next human contributor wrote one, so there is no identifiable person or company to contract with, escalate to or hold responsible.
  • Donations over the last twelve months totalled 285 US dollars and there is no commercial tier, so no paid support exists at any price and no maintenance commitment is funded.
  • The LICENSE file is Apache 2.0 with a superseding appendix that bans redistributing a paid version and refers to paid features that do not yet exist, and GitHub cannot classify it, so the terms already anticipate a commercial change of direction.
  • Releases arrive in bursts with an eleven month gap between September 2023 and August 2024 and two further gaps of about six months since, so there is no basis for assuming a security fix will land promptly.
  • The backup feature is documented as experimental, covers only the CapRover configuration directory and explicitly excludes persistent volumes and container images, so every database has to be dumped separately with its container stopped.

Icinga

  • The free core has no vendor SLA, so production incidents are supported through community channels unless a paid support subscription is purchased
  • Repository access for enterprise Linux distributions like RHEL and SLES is not free, so organisations standardised on those distributions face a real recurring cost most open source monitoring buyers do not expect
  • Enterprise modules are gated behind a separate module subscription, so some functionality demonstrated in marketing material is not part of the free core
  • Self-hosting and operating Icinga requires real Linux and monitoring expertise that a commercial SaaS tool would otherwise absorb, so total cost of ownership includes staff time not captured in the licence price
  • Pricing for the paid subscriptions varies by geographic region and is not published as a single global rate card, complicating budgeting for multinational organisations
  • The web interface and configuration language, while capable, are less immediately polished than a fully commercial tool like PRTG, and initial setup takes longer to reach a usable state

Answered from the vendors’ own pages

CapRover: Does CapRover cost anything?

No. There is no paid tier and no hosted version. The only income is donations, which came to 285 US dollars over the last twelve months.

Icinga: Is Icinga free to run in production?

Yes, the core platform has no licence fee and no limit on hosts or services monitored.

CapRover: Is the licence really Apache 2.0?

Not quite. The LICENSE file is Apache 2.0 plus an appendix that supersedes it in case of conflict, forbidding modification of paid features and redistribution of a paid version. GitHub does not recognise the result as a standard licence.

Icinga: What do the paid subscriptions actually add?

A repository subscription provides packages for certain enterprise Linux distributions, a module subscription unlocks enterprise-only add-on modules, and a support subscription bundles both with professional support.

CapRover: Does the backup feature protect my databases?

No. It backs up the CapRover configuration directory only and explicitly excludes persistent directories and container images. You have to dump each database yourself with the container stopped.

Icinga: Is Icinga related to Nagios?

Yes, it originated as a fork of Nagios but has since diverged into an independently developed platform.

CapRover: Can I move off Docker Swarm later?

Not without rebuilding. CapRover is architecturally tied to Swarm, so outgrowing it means migrating applications to a different platform rather than switching a scheduler.
