Frequently Asked Questions
Is ClusterSight really free? What is the catch?
There is no catch. ClusterSight is free and open source under the MIT license. Every feature is included, with no cluster limits, no seat limits, and no license keys.
What license is ClusterSight released under?
The MIT license. You can use, modify, and redistribute it, including inside commercial products, as long as you keep the copyright notice.
What happened to the Pro and Enterprise plans?
They are gone. Everything that used to be in Pro and Enterprise — multi-cluster support, Query Inspector, unlimited clusters — is now part of the free, open-source release.
Is there a hosted or cloud version?
No. ClusterSight is self-hosted only. You run it with Docker Compose next to your ClickHouse clusters, typically in under 8 minutes.
Does ClusterSight send my data anywhere?
No. ClusterSight runs entirely inside your infrastructure. Metrics are read from ClickHouse system tables and stored locally — nothing is sent to us.
Is ClusterSight affiliated with ClickHouse, Inc.?
No. ClusterSight is an independent open-source project and is not affiliated with, endorsed by, or sponsored by ClickHouse, Inc. ClickHouse® is a registered trademark of ClickHouse, Inc.
Can I use ClusterSight at my company?
Yes. The MIT license allows commercial use with no fees and no registration.
