ParadeDB is a PostgreSQL extension that brings advanced search and analytical capabilities to Postgres.
It is aimed at teams that want to build search-driven applications without maintaining a separate search engine, letting them keep search workloads close to their relational data and existing PostgreSQL infrastructure.
This is free and open source software.
Key Features
- Provides full-text search features including BM25 scoring, Top K retrieval, highlighting, tokenizers, and token filters.
- Supports filtering, bucket and metric aggregations, facets, and columnar storage for analytical workloads.
- Includes JOIN support so search results can be combined with relational queries inside PostgreSQL.
- Can be deployed as a self-hosted PostgreSQL extension or used as a logical replica of managed PostgreSQL services.
- Integrates with tools and platforms including Django, SQLAlchemy, Rails, Railway, Render, and DigitalOcean.
