About ClickHouse
ClickHouse is an open-source database built for analytical queries over large amounts of data. It stores data by column, which helps reports and dashboards run quickly.
What it does
ClickHouse lets you write SQL queries that scan large tables and return results quickly. It is used for real-time analytics, log and event analysis, and reporting. Teams can run it on their own servers or use the managed ClickHouse Cloud service.

Who it's for
Data engineers, analytics teams and product teams that need fast reporting over large event data. Teams building observability tools also use it as a storage and query layer.
Pricing and good to know
The core database is open source under the Apache 2.0 license, so there is no license fee to pay. The managed cloud service offers a 30-day trial with credits to start. If you self-host, plan for servers, storage and maintenance time, since those costs are yours to manage.
