OpenSearch doubles downloads as open source alternative to Elasticsearch

OpenSearch says downloads have doubled to 1.4 billion since its 2021 fork from Elasticsearch and move to Linux Foundation governance.

The project now draws contributions from more than 400 companies, signaling broad enterprise adoption of the open source search stack.

OpenSearch is pitching itself as a vendor-neutral search and AI platform with vector search, model choice, and safety tools for agentic AI.

Large deployments at companies such as Nvidia and Atlassian underscore demand for a scalable alternative that reduces vendor lock-in.
