Typesense

Open-source, typo-tolerant search engine optimized for instant results.

Typesense is an open-source, in-memory search engine built in C++ that provides fast, typo-tolerant full-text search with faceting, filtering, geo-search, and built-in vector and semantic search for hybrid retrieval. It ships with a simple REST API, clustering for high availability, and SDKs across languages. It is positioned as an open alternative to Algolia and Elasticsearch for instant-search use cases.
