LICENSE.txt states the source in this repository is available, except where a file header says otherwise, under the recipient's choice of the Redis Source Available License 2.0 (RSALv2, not OSI), the Server Side Public License v1 (SSPLv1, not OSI) or the GNU Affero General Public License v3 (AGPLv3, OSI) - the same default-triple-license shape as elasticsearch, and AGPL-3.0 is the tier this records. Unlike elasticsearch's x-pack or meilisearch's Enterprise Edition, no directory in this repository is checked to carry a header naming only the non-OSI branches - the coordinator/clustering code under `src/coord` (Redis's distributed serving layer) carries the identical triple-choice header as the rest of `src/`, so no functionality in the published tree is withheld from the AGPL-3.0 branch. Source is public and the core ungated.

  A source file inside the distributed coordinator/clustering directory (src/coord) carries the identical "your choice of RSALv2; or SSPLv1; or AGPLv3" header as the rest of the repository, rather than a header naming only the non-OSI branches - the shape that would mark a gated directory the way elasticsearch's x-pack is marked.

• https://github.com/RediSearch/RediSearch/blob/master/README.md recorded 2026-09-02

  README describes a query and indexing engine providing secondary indexing, full-text search, vector similarity search and aggregations for Redis, with no separate enterprise-only directory or paid tier described inside this repository.

6,228 GitHub stars, which lands in the 1K-10K stars band of the stars scale, level 2. RediSearch ships as a Redis module with no standalone package registry artifact and no published deployment count, which leaves the stars scale and its cap of 3.

  Repo metadata - stargazers_count = 6,228 - for RediSearch/RediSearch.

Banded on the category feature matrix as working single-purpose store or index, level with pgvector - the same shape (a search/index module bolted onto a general-purpose store, inheriting that store's persistence and distribution rather than providing its own) with a broader retrieval surface than a vector-only extension.

• https://github.com/RediSearch/RediSearch/blob/master/README.md recorded 2026-09-02

  README documents secondary indexing, full-text and vector search and aggregations as a Redis module, with no storage or clustering layer of its own beyond what Redis provides.
