Typesense

Typesense is a search engine written in C++ that developers use to add fast, typo-tolerant search to websites and apps. The vendor says searches return in under 50 ms. Besides keyword search, it supports vector and semantic search, and it can serve as a retrieval layer with its built-in RAG capability. You can set sorting, filtering and ranking at query time, so one index can serve several orderings. The core is open source under GPLv3 and is free to self-host, which suits engineering teams that want to control their infrastructure. Typesense Cloud is the managed option. It runs a dedicated cluster with no limits on records or operations, and you pay hourly for the memory, vCPU, node count and bandwidth you choose. Optional extras include high availability, GPU acceleration for generating embeddings, high-performance disk and a multi-region Search Delivery Network. The support page says cloud clusters start at about 22 USD per month. Cloud customers also get role-based access control, single sign-on, auto scaling, SOC 2 Type 2 compliance, and paid support plans with SLAs. Integrations include Laravel, WordPress, WooCommerce, Magento, Firebase, Gatsby and LangChain, client libraries for the major programming languages, InstantSearch UI adapters, DocSearch, and an MCP server that lets AI agents provision clusters. The main limitation is that Typesense is a developer tool rather than a business-user product. Reviewers say getting good relevance takes configuration, the documentation assumes technical skill, and resource-based pricing makes costs harder to forecast than fixed tiers.
