Distributed search and analytics engine with a REST API.

OpenSearch indexes and searches data for application search, log analysis, and observability workflows. It supports full-text and vector queries, with mappings and index-management tools for organizing stored information. Teams can install the suite on their chosen platform and use the companion OpenSearch Dashboards interface to analyze data and inspect application logs, metrics, and traces.

VI / Reviewed alternativesElasticsearch

Search and analytics engine workloads migrated to OpenSearch. Source-version and feature limitations apply; do not present as universal drop-in compatibility. Checked 2026-10-05

Apache Solr

Search engine workloads; documents/schema migration followed by application cutover to OpenSearch. Backfill only; no live-traffic Capture and Replay. Applications must change their query layer. Solr plugins require replacement/reimplementation. Official overview and detailed page disagree on target OpenSearch version coverage, so no target-version guarantee is made. Checked 2026-10-05
