## What it is
Typesense is an open-source, in-memory search engine written in C++ that provides fast, typo-tolerant full-text search with sub-50ms latency, plus vector/semantic search capabilities. It positions itself as an easier-to-use open-source alternative to Algolia, Pinecone, and Elasticsearch.

## Use cases
- add typo-tolerant autocomplete search to my website
- build a faceted product browsing experience for an e-commerce store
- self-host an open source alternative to Algolia
- run semantic or hybrid search over documents with vector embeddings
- add geo search to a listings site like Airbnb
- power instant search-as-you-type over millions of records
- index and search my database full-text without Elasticsearch complexity
- use a search engine as a geo-distributed cache close to users

## When to choose
- you need instant, typo-tolerant search-as-you-type with minimal configuration
- you want an open-source Algolia replacement without per-search pricing
- Elasticsearch feels too complex or operationally heavy for your use case
- you need combined full-text and vector/semantic search in one engine
- you're building e-commerce search with faceting, synonyms, and merchandising

## When to avoid
- you need a general-purpose analytics or log aggregation store - use Elasticsearch or OpenSearch
- your dataset exceeds available RAM, since Typesense is in-memory
- you need complex joins or relational queries - use a database instead
- you require a permissive license - Typesense is GPL-3.0
- you need heavy document ingestion pipelines or complex aggregations
