Infrastructure / Storage & Retrieval

ParadeDB

ParadeDB is a Postgres extension that adds a custom index for full-text search with BM25 scoring, vector search, filtering and aggregations directly inside Postgres, so application data and search live in one database rather than two systems kept in sync.

Distinct from pgvector, already on this roster - pgvector adds vector search to Postgres, ParadeDB adds a separate BM25 full-text and vector index (the pg_search extension) with aggregation support. Verified 2026-09-02 via the GitHub API and the LICENSE body.

9,221 GitHub stars, which lands in the 1K-10K stars band of the stars scale, level 2. ParadeDB ships as a Postgres extension with no standalone package registry artifact, and no deployment count is published, which leaves the stars scale and its cap of 3.

Capability

3 medium confidence

3.0

Banded on the category feature matrix as working single-purpose store or index, level with pgvector - the same shape (a Postgres extension inheriting the host database's persistence and transactions) with a broader set of retrieval modes (full-text, vector and aggregation rather than vector alone), but no distribution or clustering of its own beyond what Postgres provides, so it stays at this band rather than the one above.

README documents a Postgres extension for full-text, vector and aggregation search with no distributed cluster mode of its own.
