Elasticsearch

Elasticsearch vs OpenSearch: what is the key difference in 2026?

The question is about Elasticsearch .

Answer:
OpenSearch is an open-source fork of Elasticsearch created by Amazon in 2021 after Elastic changed its licence from Apache 2.0 to SSPL. Elasticsearch still includes proprietary features like Elastic Security and Elastic Observability. OpenSearch is the preferred choice for AWS-native deployments through Amazon OpenSearch Service. For teams needing Elastic's commercial features and Kibana, Elasticsearch is the better option. Both share the same core search engine architecture and API compatibility.
