Open-source search platform OpenSearch has recorded 1.4 billion downloads, nearly doubling in a little over 2 years since it was brought under the Linux Foundation.

According to a recent report by Techzine, Bianca Lewis, executive director of the OpenSearch Software Foundation, said at the KubeCon and CloudNativeCon event that the OpenSearch project receives contributions from more than 400 companies and records more than 1.5 million page visits a month.

OpenSearch is a project created by AWS through a fork after Elasticsearch shifted to a restrictive licensing model in 2021. AWS later donated OpenSearch to the Linux Foundation. Lewis said it was a judgement that no vendor should manage OpenSearch, adding that the number of contributors, downloads and commits rose notably after the move under the foundation.

Lewis stressed that, compared with closed platforms, data sovereignty and business models should be weighed before features. "If you choose a project controlled by a specific company, you hand over control of data and pricing decisions to that company," she said.

OpenSearch is based on a model-neutral architecture that includes vector search as a default feature and allows free choice of AI models.

It also supports agentic AI safety features that track AI agent behaviour in real time, detect anomalies and send warnings before problems occur.

Adoption cases are also increasing. Nvidia adopted OpenSearch as the AI backbone for its NeMo platform, and Atlassian operates billions of documents across more than 300 search clusters this year with uptime of more than 99.99 percent. Changi Airport is using OpenSearch for retail search across more than 1,000 stores and for a real-time product recommendation system.
