OpenSearch is an open-source, distributed, RESTful search and analytics suite for full-text search, log analytics, application monitoring, and vector search. It is a community-driven Apache-2.0 fork of Elasticsearch 7.10 maintained under the Linux Foundation.
Use cases
- add full-text search to my application or website
- store and query logs for observability
- use a vector database for semantic search
- monitor application metrics and traces
- run analytics dashboards over large datasets
- self-host an Elasticsearch-compatible search engine
When to choose
- you need a scalable, self-hosted distributed search engine with an Apache-2.0 license
- you want combined full-text, analytics, and vector search in one system
- you need an open-source Elasticsearch-compatible alternative without Elastic's license changes
- you want log and application monitoring with a visualization UI (OpenSearch Dashboards)
When to avoid
- you need a lightweight embedded search index for a small app
- you prefer a managed search service over operating a cluster
- your stack depends on features exclusive to newer Elasticsearch versions
- you only need simple keyword search that a database full-text index could handle
