base on 🛰️ An approximate nearest-neighbor search library for Python and Java with a focus on ease of use, simplicity, and deployability.  [](https://github.com/spotify/voyager/blob/master/LICENSE) [](https://spotify.github.io/voyager) [](https://pypi.org/project/voyager) [](https://pypi.org/project/voyager) [](https://github.com/spotify/voyager/actions/workflows/all.yml) <!-- [](https://pypi.org/project/voyager) --> <!-- [](https://pypi.org/project/voyager) --> <!-- [](https://pypistats.org/packages/voyager) --> <!-- [](https://github.com/spotify/voyager/stargazers) --> **_Voyager_** is a library for performing fast approximate nearest-neighbor searches on an in-memory collection of vectors. Voyager features bindings to both Python and Java, with feature parity and index compatibility between both languages. It uses the HNSW algorithm, based on [the open-source `hnswlib` package](https://github.com/nmslib/hnswlib), with numerous features added for convenience and speed. Voyager is used extensively in production at Spotify, and is queried hundreds of millions of times per day to power numerous user-facing features. Think of Voyager like [Sparkey](https://github.com/spotify/sparkey), but for vector/embedding data; or like [Annoy](https://github.com/spotify/annoy), but with [much higher recall](http://ann-benchmarks.com/). It got its name because it searches through (embedding) space(s), much like [the Voyager interstellar probes](https://en.wikipedia.org/wiki/Voyager_program) launched by NASA in 1977.
