quivr

Quivr is an open-source engine that ingests content streams durably and provides fast hybrid search, change feeds, and alerts. It uses a modular plugin architecture for normalizers, embedding models, and ranking rules, integrating with PostgreSQL, S3, Temporal, and Weaviate. Users can run it locally via Docker Compose or deploy it on servers and cloud platforms using its unified Go binary.
