Typesense

Typesense is an open-source, typo-tolerant search engine optimized for instant search-as-you-type experiences. Built in C++ for raw performance, it delivers sub-50ms search results even on modest hardware. Unlike Elasticsearch which requires significant operational overhead, Typesense is designed to be simple to set up and run. A single binary handles indexing, searching, and replication with minimal configuration. Its standout features include automatic typo correction, faceted search and filtering, geo-search for location-based queries, vector search for AI-powered semantic matching, and join-like operations across collections. The search API supports sorting, grouping, pinning, and custom ranking formulas. Typesense handles synonyms, stop words, and stemming out of the box. It supports high availability through a built-in Raft-based clustering protocol. Client libraries are available for JavaScript, Python, Ruby, PHP, Go, Java, C#, and more. Typesense Cloud offers a managed service with automatic scaling. For developers building search-heavy applications like e-commerce stores, documentation sites, or SaaS dashboards, Typesense provides Algolia-quality search at a fraction of the cost.
