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.; Thanos several components — sidecar, store, querier, compactor, ruler — each with its own configuration and failure modes
  • They diverge on capability: CapRover covers One-click applications, Thanos covers Global query.
  • 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.

Thanos

  • Several components — sidecar, store, querier, compactor, ruler — each with its own configuration and failure modes
  • The compactor is a common source of operational trouble and must not run twice against the same bucket
  • Query latency over object storage is meaningfully higher than local Prometheus
  • Object storage costs and API request charges become real at high volume

Both have a free tier, so you can try either at no cost before committing.
What is CapRover best used for?
CapRover is most often used for running a personal server or homelab with several applications behind automatic certificates, a two person team that wants a dashboard rather than a terminal for deployments on one box, standing up one-click databases and internal tools without writing compose files, hosting client demos cheaply where downtime is inconvenient rather than expensive. Of those, running a personal server or homelab with several applications behind automatic certificates and a two person team that wants a dashboard rather than a terminal for deployments on one box are not what Thanos is typically brought in for.

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.

Thanos: Is Thanos free?

Yes, open source and CNCF-incubating. Costs are the object storage it uses.

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.

Thanos: Does Thanos replace Prometheus?

No. It runs alongside existing Prometheus servers, adding global query, deduplication and long-term storage.

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.

Thanos: Thanos or VictoriaMetrics?

Thanos layers onto Prometheus using object storage and is the more established multi-cluster answer. VictoriaMetrics is a separate store aiming at lower resource use and fewer moving parts.

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.
