RediSearch offers a choice of three licenses, the same choice as Elasticsearch: the Redis Source Available License, the Server Side Public License, or AGPL-3.0, which is OSI-approved. No directory, including the distributed clustering code, is restricted to only the non-OSI choices, unlike Elasticsearch's x-pack or Meilisearch's Enterprise Edition, so nothing in the published tree is withheld from the AGPL-3.0 option.

  Repo metadata - license spdx_id NOASSERTION, private false, archived false, default branch master - for RediSearch/RediSearch.

• https://github.com/RediSearch/RediSearch/blob/master/LICENSE.txt recorded 2026-10-07

  LICENSE.txt states the source is available under the recipient's choice of RSALv2, SSPLv1 or AGPLv3 starting with Redis 8, except as otherwise specified in source code headers for specific files.

• https://github.com/RediSearch/RediSearch/blob/master/README.md recorded 2026-10-07

  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.

• https://github.com/RediSearch/RediSearch/blob/master/src/coord/dist_plan.h recorded 2026-10-07

  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.

RediSearch ships as a Redis module with no standalone package-registry artifact of its own and no published deployment count. That leaves GitHub stars as the adoption signal available for it.

• https://api.github.com/repos/RediSearch/RediSearch recorded 2026-09-02

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

RediSearch adds secondary indexing, full-text search, vector similarity search and aggregations as a Redis module, inheriting Redis's own persistence, replication and clustering rather than providing its own. That puts it on par with pgvector, a search extension bolted onto a general-purpose store, though with a broader retrieval surface.

• https://github.com/RediSearch/RediSearch/blob/master/README.md recorded 2026-10-07

  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.
