OpenSearch is not Elasticsearch

It is a common misconception that both Elasticsearch and OpenSearch are similar search engines. However, Elasticsearch continues to surpass OpenSearch in innovation and features, leading to superior performance. Elasticsearch has achieved enhanced scalability and efficiency with a notably reduced resource footprint, resulting in a better ROI. Elasticsearch and OpenSearch are not the same.

Pace of Innovation

4x number of features

Since the fork of an older version of Elasticsearch, OpenSearch hasn't kept up with the pace of innovation. Since OpenSearch GA, Elasticsearch has outpaced feature innovation by 4x.

Search-powered solutions

Adopt ready-to-use solutions for your search, observability, and security needs.

  • image_alternative_text: blt4c95fef51f752b47

    Build applications using flexible tools, robust APIs, and the trusted power of Elasticsearch. Use pre-built search solutions for enterprise needs like workplace search, application search, and customer support.

  • image_alternative_text: blt6e3875f2cb65b010


    Apply search and visualization to logs, metrics, APM traces, and uptime statistics for unified end-to-end visibility into your technology ecosystem.

  • "all": "Elastic Security"


    Address your security needs for SIEM, SOAR, threat intelligence, XDR, endpoint security, and cloud security, so your analysts can use the power of search and visualization to prevent, detect, and respond to threats.

Savings, deployment flexibility, and search innovations

Deployment, subscription, and purchasing options, so you get what you want.

  • Cost-effective storage options with searchable snapshots

    Elastic gives you the ability to classify and store your data in a way that delivers a balance between performance and cost savings. Save money with searchable snapshots.

    Leverage hot, warm, cold, and frozen data tiers, and searchable snapshots to search for data inside Elasticsearch, as well as data residing in cloud-based object storage.

  • A unified search experience across locations

    Unify search experiences with capabilities like cross-cluster search and cross-cluster replication. Both of these capabilities allow federated search and analytics across clusters, cloud providers, and regions, while retaining parts of the data on-premises, or in a specific preferred cloud provider or region.

  • Build AI search into your applications

    The Elasticsearch Relevance Engine™ (ESRE) is designed to power artificial intelligence-based search applications. Use ESRE to apply semantic search with superior relevance out of the box (without domain adaptation), integrate with external large language models (LLMs), implement hybrid search, and use third-party or your own transformer models.

  • Commercially supported self‑managed offering

    Elastic gives you the flexibility to create and run deployments where and how you need them to meet your business objectives — whether public cloud, private cloud, multi-cloud, hybrid, or on-premises.

    With Elastic you can purchase and manage your own search implementation, which is useful for use cases with specific regulatory and data residency requirements.

  • Tiered subscription levels

    Get access to the features you want, and the level of technical support that meets the needs of your business. Easily switch between Standard, Platinum, and Enterprise subscription levels without having to contact sales.

  • Flexible purchasing options

    Purchase from us, or through your preferred cloud marketplace (AWS, Google Cloud, or Microsoft Azure). Marketplace purchases benefit from any discounts you may have negotiated with your cloud provider, and usage accrues toward your cloud spending commitment.
