OpenSearch is a free, community-driven, open-source suite for ingesting, searching, visualizing, and analyzing data. It includes a data store and search engine, OpenSearch Dashboards, and the Data Prepper server-side collector. Search functions include full-text and field queries, multi-index search, field boosting, score-based ranking, sorting, and aggregations. The project identifies search, observability, and security analytics as application areas, including log analysis, threat intelligence, and event correlation. Listed machine-learning and AI capabilities include vector search and anomaly detection. OpenSearch can be deployed on premises or in hybrid and multicloud environments. Its Apache License 2.0 permits use, modification, extension, embedding, monetization, and resale. It is compatible with Beats, Fluent Bit, and Fluentd for ingestion and processing. A read-only ODBC driver for Windows and macOS connects tools such as Tableau, Microsoft Excel, and Power BI to the SQL plugin. Dashboards provides visualizations and an interface for plugins including security, alerting, Index State Management, and SQL. The downloads page warns that minimal distributions lack security features and are intended for carefully controlled environments or embedding in another service.
