Stoolap is an embedded SQL database written in pure Rust. It combines transactional workloads (OLTP), analytical queries (OLAP), and native vector search in a single serverless runtime.

Historical note: Stoolap started as an early Go prototype. The project is now fully migrated to Rust, and all active development and releases happen in the Rust codebase.

• Embedded first architecture with no external database server
• Modern SQL engine with MVCC and cost based optimization
• Native vector and semantic search with HNSW
• Predictable performance for real time applications
