What the free edition leaves out
Scroll sideways to view all columns →The free edition is genuinely usable, but some team or enterprise features need a paid plan. “Not confirmed” means the official pages we read did not say, so we do not guess.
| Feature | Free edition | Details | Source |
|---|---|---|---|
| SSO / SAML | Not confirmed | The pricing page lists SAML single sign-on under the ClickHouse Cloud Enterprise plan. It does not say whether the open source server has single sign-on. | Source ↗ |
| Role-based access control | Free | The access-rights documentation describes users, roles, GRANT and REVOKE privileges, settings profiles, and points to a separate page for ClickHouse Cloud. | Source ↗ |
| Audit logs | Not confirmed | Audit logs are not described on the pages read. | Source ↗ |
| Multi-user / teams | Free | The access-rights documentation describes creating and managing multiple user accounts with CREATE USER and related queries. | Source ↗ |
| Backups and restore | Free | The backup documentation describes BACKUP and RESTORE commands with full and incremental backups. | Source ↗ |
| API access | Free | The documentation describes an HTTP interface, for example queries sent to port 8123 with curl. | Source ↗ |
| Support SLA | Paid | Support response times are listed on the pricing page for the paid ClickHouse Cloud plans: one business day on Basic, one hour for severity 1 issues on Scale, and 30 minutes plus a named support engineer on Enterprise. It also points to the forever-free open source distribution. | Source ↗ |
Best for
Teams running real-time analytics, event data or log storage that outgrow a general-purpose database and want an open-source columnar engine.
Why choose it over Snowflake
The database is Apache-2.0 and can be installed with one command on your own servers. ClickHouse's comparison pages position it as a lower-latency alternative to Snowflake and BigQuery for dashboards and user-facing analytics. Its documentation covers users, roles, backups and an HTTP interface.
Where it falls short
It is an analytics engine, not a transactional database, and you operate clustering, upgrades and backups yourself when self-hosting. SAML single sign-on, private regions, compliance options and faster support response times are listed only on ClickHouse Cloud plans. The comparison pages with Snowflake and BigQuery are published by ClickHouse itself and include vendor-reported speed and cost figures.
Open-source alternative to
- Snowflake — ClickHouse's own comparison page positions it against Snowflake for data warehousing and real-time dashboards and links a migration guide, so it can replace Snowflake as the analytics database.
- BigQuery — ClickHouse publishes a comparison with BigQuery, so it can replace BigQuery as the analytics database, either self-hosted or on ClickHouse Cloud.
