libSQL

libSQL is an open-source fork of SQLite adding features including native vector search, designed for edge and embedded deployments. Free and open-source (MIT). Turso provides managed libSQL cloud service with free tier (500 databases, 9GB storage) and Pro at $29/month. Key additions over SQLite include native vector embeddings (no extension needed), ALTER TABLE improvements, and replication capabilities. The native vector support enables F32_BLOB type and vector_distance functions built into core database. Edge replication enables globally distributed read replicas with single primary. For text-to-SQL: combines SQLite simplicity with built-in vector capability for edge-deployed RAG applications. Turso’s edge replication enables low-latency access worldwide. The platform targets edge computing, serverless functions, and applications requiring both relational and vector capabilities without operational complexity.
