Orama

Full-text and vector search engine in under 2KB

Orama is a complete search engine and RAG pipeline that runs in browsers, servers, and edge environments in under 2KB. It provides full-text search, vector search, and hybrid search with built-in faceting, filters, geo-search, and typo tolerance. Orama requires no external dependencies and works entirely client-side for instant search experiences, or server-side with Node.js and Deno for larger datasets.

About Orama

Orama rethinks search infrastructure by delivering a fully functional search engine small enough to ship directly in client-side JavaScript bundles. At under 2KB gzipped, it adds negligible overhead while providing full-text search with BM25 ranking, vector similarity search for semantic queries, and hybrid search that combines both approaches. This eliminates the need for server roundtrips in many search scenarios, enabling instant results as users type.

Beyond basic search, Orama includes built-in faceted filtering, geospatial queries, typo tolerance with configurable distance thresholds, stemming, stop words, and result highlighting. Its vector search supports cosine similarity and dot product metrics with configurable dimensions, making it suitable for embedding-based RAG applications. The library handles schema definition, document insertion, and index management through a clean JavaScript API that works identically across browser, Node.js, Deno, and Bun runtimes.

With over 10,300 GitHub stars and funding behind it, Orama has carved out a unique position as the embeddable search solution for AI-powered applications. The open-source library under Apache-2.0 handles local search, while Orama Cloud provides managed infrastructure for larger deployments with analytics, A/B testing, and a visual dashboard. For developers building AI coding tools, documentation sites, or knowledge bases that need fast client-side search, Orama offers a compelling zero-infrastructure alternative.
