What is Typesense?

Typesense is an incredibly fast search engine that can tolerate typos, allowing you to quickly and accurately search your data even if you make mistakes while typing. Unlike other search engines such as Algolia and Elasticsearch, Typesense is open source, which means that you can use it for free and modify it to suit your needs with confidence.

Typesense is designed to be user-friendly, even if you're not a search engine expert. Its cutting-edge search algorithms take advantage of the latest hardware capabilities so that you can get the best performance for your applications. Additionally, Typesense is privacy-friendly, demonstrating its respect for the privacy of your users.

With Typesense, you can create a plethora of search experiences. From blazing-fast search experiences to faceted navigation experiences, geo-search, vector search, semantic search, similarity search, and more. Typesense enables you to make your applications more user-friendly, ultimately helping your users find what they're looking for easily and with confidence.
