Clickhouse

clickhouse.com/

ClickHouse is a column-oriented SQL database built for real-time analytical queries over large datasets, pitched here as "the leading database for AI" for teams building agentic systems that need millisecond queries at petabyte scale. The homepage runs a client logo carousel dense enough to include Meta, Spotify, Cisco, and Cloudflare, then backs open-source credibility with exact GitHub figures — 50k+ stars, 3.2k+ contributors, 868+ releases. A dedicated "Why is ClickHouse so Fast?" section runs a visual row-vs-column comparison rather than asserting speed as a bare claim, and a banner announces the recent acquisition of Langfuse for LLM observability. Cloud pricing is stated directly: plans start at $50/month.
