The Nextflow plugin registry

The Nextflow plugin registry is a central repository for Nextflow plugins. It hosts an index of plugin metadata that supports plugin discovery, accessibility, and version tracking.

Nextflow 25.04 and later can use the plugin registry as a drop-in replacement for the legacy plugin index hosted on GitHub. See Migrating to the Nextflow plugin registry for more information about migrating to the Nextflow plugin registry.

Note

The Nextflow plugin registry is currently available as a public preview. Plugin developers can access the registry by contacting info@nextflow.io to obtain registry access tokens.
