# Embedded Database

High-performance on-device object and vector database for mobile and edge AI

High-performance on-device object and vector database designed for mobile, IoT, and edge applications, providing sub-millisecond local HNSW vector search and optional cloud-optional data synchronization.

In-process analytical SQL database

DuckDB is a high-performance analytical database that runs as an in-process SQL OLAP engine. Unlike traditional client-server databases, DuckDB embeds directly within your application, similar to SQLite but optimized for analytical queries. It supports complex SQL including window functions, CTEs, and nested types while processing columnar data with vectorized execution. DuckDB reads Parquet, CSV, JSON, and Arrow formats natively and integrates with Python and R data science workflows.
