Elasticsearch vs OpenSearch (2026): tradeoffs and verdict
Same Lucene roots, different vendors: Elasticsearch tracks Elastic’s commercial roadmap; OpenSearch emphasizes open governance and common cloud paths (notably AWS).
Last updated:
Overview
OpenSearch forked from Elasticsearch after license changes—both still feel similar day to day because they share Lucene DNA. The fork shows up in licensing, release governance, managed-service defaults, and which commercial features ship where.
Compare total cost: Elastic Cloud vs AWS OpenSearch Service, support SLAs, security SKUs you actually need, and upgrade cadence your SRE team can absorb. Feature parity is close; vendor and policy fit usually decide.
