ClickHouse

The data platform powering the AI era. Speed, scale, and cost-efficiency - without compromise. clickhouse.com/cloud

Last updated: . For recent data, use our API.

Overview

ClickHouse is a fast, open-source columnar database built for real-time data processing and analytics at scale. ClickHouse Cloud delivers the query speed and concurrency that applications demanding instant insight from large volumes of data require. As AI agents become more embedded in software, generating higher query volumes at tighter latency, ClickHouse provides a high-throughput, low-latency engine purpose-built for that workload.

The company's platform supports use cases including real-time analytics, observability, data warehousing, and machine learning and generative AI workloads such as vector search. For observability, it offers ClickStack, an open-source stack for storing and querying logs, metrics and traces. Customers named by the company include Sony, Lyft, Cisco, GitLab, Tesla and Anthropic.

ClickHouse Cloud is available on AWS, GCP and Azure and through their marketplaces, while the open-source server can be self-managed at no cost. ClickHouse Local runs queries on local files such as CSV, TSV and Parquet without a server. The database uses compression and vectorized query execution, works with SQL, and offers more than 100 integrations for data ingestion, visualization and language clients.
