BUILT FOR SCALE

## Engineered for the hardest analytics workloads.

Columnar storage, vectorized execution, and per-partition parallelism — ClickHouse turns single-node hardware into a distributed analytics cluster.

### Sub-second on petabytes.

Vectorized SQL engine reads only the columns you query. Compress 10× without losing speed.

### Real-time ingest.

Stream from Kafka, Kinesis, or HTTP. Query rows the moment they land — no batch window.

### One node, or a fleet.

Run on a laptop, scale to thousands of replicas — the same SQL, the same storage format.

### SQL you already know.

ANSI-SQL with JSON, geo, vector, and time-series functions bolted on without ceremony.

### Open-source, always.

Apache 2.0. 47k stars, 2.8k contributors. Run it self-hosted or use ClickHouse Cloud.

### Multi-tenant ready.

Quotas, row-level security, and resource pools per workload — designed for shared infra.

CLICKHOUSE CLOUD

## Your data warehouse,
without the warehouse.

A fully-managed ClickHouse service that auto-scales storage and compute independently. No clusters, no babysitting — just SQL.
