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.; OpenSearch diverged from Elasticsearch since 7.10, so clients, plugins and features no longer map one to one
  • They diverge on capability: CapRover covers One-click applications, OpenSearch covers Full-text search.
  • 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.

OpenSearch

  • Diverged from Elasticsearch since 7.10, so clients, plugins and features no longer map one to one
  • Operationally heavy in the way Elasticsearch is: cluster sizing, shard strategy and JVM tuning are ongoing work
  • Smaller ecosystem of third-party tooling than Elasticsearch, which most integrations still target first
  • Overkill for plain application search, where a dedicated search engine is far simpler

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.

OpenSearch: Is OpenSearch free?

Yes, Apache 2.0 licensed under the Linux Foundation. Amazon OpenSearch Service is a paid managed option.

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.

OpenSearch: Why does OpenSearch exist?

Elastic moved Elasticsearch off the Apache 2.0 licence in 2021. AWS forked the last Apache-licensed version, and the project now sits under the Linux Foundation.

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.

OpenSearch: Is OpenSearch compatible with Elasticsearch?

It was at the 7.10 fork point. Both have developed independently since, so compatibility weakens with every release and should be verified for the features you use.

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.
