Overview

Typesense is an open-source search engine written in C++ and released under the GNU GPL version 3. It keeps indexes in memory for low-latency, typo-tolerant instant search with faceting, filtering, sorting, geosearch, synonyms, curation rules and grouping, all driven by a simple REST API and official clients for JavaScript, Python, PHP, Ruby, Go, Java, Swift and .NET. Later releases added vector search, hybrid keyword-plus-semantic ranking with built-in or remote embedding models, conversational search backed by LLMs, and a multi-node clustering mode using Raft for high availability. Typesense Cloud is the managed service operated by the same company.

Typesense positions itself as an open-source alternative to hosted search APIs for websites and applications. Memory residency makes very large corpora expensive, the GPL may matter for teams embedding it in proprietary distributions, and aggregation-heavy analytics are outside its scope.

Capabilities

  • In-memory typo-tolerant instant search
  • Faceting, filtering, grouping and geosearch
  • Vector and hybrid search with embedding models
  • Conversational (RAG) search
  • Raft-based multi-node high availability
  • REST API with clients in eight languages

Typical workflows

  1. E-commerce or catalog search with facets
  2. Documentation and site search
  3. Hybrid semantic search for an application

Strengths

  • Simple configuration and predictable relevance
  • Clustering for availability
  • Managed cloud from the project maintainers

Limitations

  • Indexes must fit in memory
  • GPL-3.0 license
  • Not designed for analytics or log search

Prerequisites

  • A server with enough RAM for the index, or Typesense Cloud

Who it is for

  • Web and mobile developers adding search
