Typesense is a fast, open-source, typo-tolerant search engine, designed as a simple and sovereign alternative to Algolia and Elasticsearch. It returns results in milliseconds, as you type, providing the smooth “search-as-you-type” experience your users expect from a modern website or application.

Its built-in typo tolerance automatically corrects input approximations to always suggest relevant results. Typesense handles facets, filters, sorting, geosearch, synonyms, and vector / semantic search — ideal for combining keywords and AI relevance, including in RAG scenarios.

On the integration side, it exposes a simple REST API, client libraries in many languages, ready-to-use search widgets (InstantSearch), and a restricted API key system per collection. Lightweight to deploy in Docker, managed by DINAO and hosted in France, Typesense brings professional-grade search without entrusting your data to a foreign service.
