Inillucent is an embedded database from Black Rainbow Labs that combines a SQLite-style SQL interface with vector embeddings and semantic search. Its documentation presents examples of joins, recursive queries, upserts, foreign keys and other SQL operations alongside similarity-search queries. The project is written in Rust and exposes command-line and MCP tools for working with the database.
The product targets agent applications that need structured records and retrieval by meaning in the same system. It describes a single database file with multi-process access and support for generating or using embeddings within search workflows. The vendor also publishes performance comparisons, but those workload-specific claims are not a guarantee for a different application. Teams considering it should test the SQL features, bindings and recovery behavior their own deployment requires rather than assuming compatibility from a headline.
