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
