MyScale

MyScale is a SQL vector database built on a ClickHouse fork (MyScaleDB), combining high-performance vector search, full-text search, and analytical SQL in a single engine. Its primary interface is SQL executed over the ClickHouse-compatible HTTP interface (HTTPS on port 8443), where vector similarity search is expressed with SQL functions like distance() against VECTOR INDEX columns. A managed MyScale Cloud console provisions clusters, and the underlying MyScaleDB is open source under Apache-2.0.

MyScale publishes 1 API on the APIs.io network: Query API. Tagged areas include Vector Database, SQL, ClickHouse, Vector Search, and Full-Text Search.

MyScale’s developer surface includes authentication, documentation, engineering blog, and 8 more developer resources.
