BM25 full-text search that actually finds what you type — fuzzy substrings across token boundaries, accent-insensitive, with byte-offset highlights. Python + Rust, built for hybrid search with vector DBs.
An embedded analytical database written in Rust, compatible with DuckDB. Its own columnar format with global dictionaries and multi-column compression, and operators that run directly on the encoded data. The bar is 10x DuckDB on ClickBench at a tenth of the disk.
Prolly is a content-addressed ordered map built on prolly trees. It gives applications immutable snapshots, cheap branching, structural sharing, efficient diffs and merges, sync primitives, and verifiable key/range proofs.
