 WorkflowHub is based on the [SEEK platform](/products/seek/) using [Common Workflow Language](/activities/cwl/) and [RO-Crate](/products/researchobject/) to glue in federated workflow and tool descriptions across the research infrastructures. It is integrated with the [Life Science Login](https://lifescience-ri.eu/ls-login/), [GA4GH TRS API](https://about.workflowhub.eu/developer/trs/), [European Galaxy service](https://usegalaxy.eu/), [LifeMonitor](https://lifemonitor.eu/), [ELIXIR's Tool registry bio.tools](https://bio.tools/) and other services. WorkflowHub is an [EOSC service](https://marketplace.eosc-portal.eu/services/workflowhub-2d3acb63-8481-4cbd-819f-55bee294bedc).
