MyScaleDB

MyScale is a cloud database that combines vector search with SQL analytics. It is built on the open source ClickHouse database and handles structured data and vector embeddings in one system, so a single SQL query can mix vector similarity, filters, full text search and joins. The vendor says its proprietary MSTG vector engine uses NVMe SSDs and outperforms specialized vector databases on speed and cost. It is aimed at developers building retrieval augmented generation and other AI applications who prefer plain SQL to a custom API. The documentation covers vector search, text search, hybrid search, joint queries, capacity planning, multi tenancy and access control. Client libraries exist for Python, Node.js and Go, with a JDBC driver and an HTTPS interface, and integrations include OpenAI, LangChain, LlamaIndex and a telemetry feature for observing LLM systems. Clusters are managed through a web console with SQL execution. The pricing page is organized around cluster pods. It shows a starting price of $68 per month, quoted also as $0.094 per hour for 30 days, and includes an estimator where the user picks a pod size and number of replicas to see the monthly and hourly cost. The documentation offers a free sign up. MyScale is operated by MOQI Singapore Pte. Ltd.
