Source: https://clickhouse.com/pricing
Can ClickHouse be self-hosted?
Yes. ClickHouse can be deployed cloud / SaaS, hybrid and self-hosted, so it does not have to run on the vendor's infrastructure.

What does ClickHouse integrate with?
We have confirmed 11 integrations for ClickHouse, including Amazon S3, Kafka, Airbyte, Vector, PostgreSQL, MySQL, Microsoft Azure Data Factory and dbt, plus 3 more. This is what we could verify from public sources, so the vendor may support others we have not indexed.
Source: https://clickhouse.com/pricing
What security certifications does ClickHouse have?
We have independently confirmed SOC 2, ISO 27001, HIPAA and GDPR for ClickHouse. Certifications we do not list are ones we have not been able to verify from public sources, which is not the same as ClickHouse not holding them. Always confirm compliance directly before you rely on it.

Is ClickHouse open source?
Yes. ClickHouse is published under the Apache-2.0 licence, a permissive licence that generally allows commercial use and modification. Licence terms can change between releases, so verify against the repository for the version you intend to use.

The vioscaleAI score: one lens on the evidence
Not user reviews and not a paid placement: a confidence-weighted blend of the independent signals below (adoption, activity, security posture, and more), which you can sort and re-weight yourself. Vendors can correct their listing but can never move their rank, and stars are weighted low as a vanity metric. It is one way to read the evidence for ClickHouse, not the verdict.
