Scalable Sharing with Nextstrain Groups

We want to enable research labs, public health entities and others to share their datasets and narratives through Nextstrain with complete control of their data and audience. Nextstrain Groups is more scalable than community builds in both data storage and viewing permissions. Datasets in a public group are accessible to the general public via, while private group data are only visible to logged in users with permission to see the data. A single entity can manage both a public and a private group in order to share data with different audiences.

For more details about Nextstrain Groups, please see our documentation. For an alternative approach to sharing data through which leverages GitHub repositories, please see Community data sharing.

Nextstrain Groups is still in the early stages and require a Nextstrain team member to set up and add users. Please contact us at and we’d be happy to set up a group for you.
