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.; Kustomize no packaging or distribution story, which is exactly what Helm charts provide
  • They diverge on capability: CapRover covers One-click applications, Kustomize covers Overlay patching.
  • Prices and features above were last checked on 31 August 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.

Kustomize

  • No packaging or distribution story, which is exactly what Helm charts provide
  • Deeply nested overlays become hard to follow, and reasoning about the final output requires building it
  • No release lifecycle: nothing tracks what is installed or supports rollback the way Helm does
  • Patch syntax is fiddly for anything beyond simple field replacement

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.

Kustomize: Is Kustomize free?

Yes, open source and part of the Kubernetes project.

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.

Kustomize: Kustomize or Helm?

Kustomize patches plain YAML and keeps bases readable; Helm templates and packages applications with a release lifecycle. Many teams use both — Helm to install third-party charts, Kustomize to patch them.

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.

Kustomize: Do I need to install Kustomize?

No. It is built into kubectl, available through kubectl apply -k.

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.
