ClickHouse

ClickHouse provides an open-source database system for real-time analytical reporting. Put simply, it is about storing and querying application data reliably.

The natural audience is developers and data teams. They also list Analytics, Artificial Intelligence (AI), Big Data and Database, so expect those to show up in the feature set. They are a mid-sized team, 201 to 500 people, which usually shapes who they work with.

ClickHouse is based in Palo Alto, California. More on clickhouse.com.

Our checklist for this category: managed options, backups, and scaling costs. Ask for a trial on your own data, not a canned demo.

If you have worked with ClickHouse, tell the next buyer what you paid and what surprised you. That is the part of this page we cannot write.
