Overview

ClickHouse is an open-source, column-oriented OLAP database for analytical queries over large datasets, using compression and vectorised query execution. It can be self-hosted, run against local files (CSV, TSV, Parquet) without a server, or used as ClickHouse Cloud on AWS, GCP and Azure. Related products cover observability (ClickStack), managed Postgres and an in-process engine (chDB).

Best for: Engineering teams running real-time analytics, observability or BI queries over very large datasets
Pricing: The open-source distribution is free to self-host; ClickHouse Cloud is metered at $25.30 per 1TB of storage per month plus compute from $0.2181 to $0.3903 per unit/hour across three plans, and the site's FAQ states Cloud starts at $50/month.
Runs on: WebmacOSCLI

Column-oriented storage with compression and vectorised execution
Queried with plain SQL; 100+ listed integrations and BI connectors
Runs self-hosted, on local files, or managed on AWS, GCP and Azure

Trade-offs

Metered storage, compute, egress and ingest make bills hard to predict
