OpenSearch Named a Leader in GigaOm Radar for Vector Databases

AMSTERDAM — The OpenSearch Software Foundation announced at KubeCon + CloudNativeCon Europe 2026 that OpenSearch has been named a Leader and Fast Mover in the 2025 GigaOm Radar for Vector Databases v3. The foundation also pointed to a new report from S&P Global Market Intelligence 451 Research that it said shows growing enterprise adoption of hybrid and vector-augmented search for AI applications.

The GigaOm analysis highlighted OpenSearch support for hybrid search across dense and sparse vectors, scalable indexing and k-nearest neighbor performance, and flexible relevance tuning. The foundation said OpenSearch is positioned to unify vector retrieval with traditional full-text search, filtering and aggregations for enterprise AI use cases including semantic search, observability and retrieval-augmented generation.

“OpenSearch represents a compelling choice by combining proven scalability, comprehensive functionality, and open source economics that reduce risk and enhance innovation velocity,” said Howard Holton, CEO at GigaOm. The S&P Global report cited by the foundation estimated the vector-supported database market at $454.4 million in 2024 and projected a 49% compound annual growth rate through 2029.

“Recognition from independent analysts reflects what we’re hearing from organizations across the industry: AI applications require retrieval infrastructure that is open, flexible and built to scale,” said Bianca Lewis, executive director of the OpenSearch Software Foundation. The foundation said copies of the GigaOm Radar and the commissioned 451 Research report are available for download.
