Specific characteristics

OpenSearch is a highly scalable and extensible open-source software suite for search, analytics, observability, and other data-intensive applications. Powered by Apache Lucene and built and maintained by the OpenSearch Project community, OpenSearch gives developers an end-to-end toolset for building secure, high-performance, cost-efficient solutions to ingest, search, analyze, visualize, and uncover insights from their data.

Competitive advantages

Distributed as fully open source under Apache License, Version 2.0 (ALv2), OpenSearch comes with no licensing cost. Users are free to deploy, enhance, and extend the software as they see fit.

The OpenSearch Project community maintains the OpenSearch codebase in public repositories and invites contributions from the public, with no contributor license agreements or other obstacles to building and collaborating.

OpenSearch is supported by a community of users and vendors. OpenSearch users can add to or improve on the toolset for their own benefit, or contribute their enhancements back to the community.

OpenSearch supports distributed processing, allowing users to scale resources horizontally for added capacity and performance. Highly configurable deployment topologies allow OpenSearch users to fine-tune cost-performance on their clusters. Users can add and manage nodes and clusters from a single interface to keep resources aligned with demand.

A diverse ecosystem of OpenSearch partners offers a rich selection of OpenSearch-powered solutions as well as consulting services to help the community extract added value from OpenSearch tools.
