# Crate.io (CrateDB)

> Crate.io is the company behind CrateDB, a distributed SQL database for real-time analytics on large volumes of operational data. CrateDB unifies time-series, JSON/document, full-text search, vector, geospatial, and relational data behind standard SQL, is PostgreSQL wire-protocol compatible, and is built on Lucene. Developers use CrateDB through a JSON-over-HTTP SQL endpoint (POST /_sql, port 4200) and manage the CrateDB Cloud service through the CrateDB Cloud REST API. CrateDB Cloud is certified to ISO 27001 and SOC 2 Type II.
