Lightning-fast search engine you can self-host or run in the cloud
Results return in under 50 milliseconds with sensible defaults, so it works on first deploy without a tuning project.
Combine keyword relevance with vector-based semantic understanding in a single unified retrieval layer.
Build complex search UIs with a mature toolkit for filters, facets, custom ranking rules and location-aware results.
Store and retrieve embeddings for similarity search, automated embeddings and retrieval-augmented generation workloads.
Open-source, high-performance vector search at any scale
Built entirely in Rust with SIMD and a custom Gridstore storage engine for fast, scalable vector search.
Combine dense and sparse vectors in one query, supporting BM25, SPLADE++ and miniCOIL for keyword-plus-vector retrieval.
Store metadata as JSON and apply advanced filters such as nested, text, geo and has_vector, with filters applied during HNSW traversal.
Asymmetric, scalar and binary quantization reduce memory usage by up to 64x while preserving search quality.
