Nextflow is a workflow manager that enables scalable and reproducible workflows. Nextflow is complemented by the nf-core community effort that aims at developing and supporting a curated collection of Nextflow pipelines, developed according to a well-defined standard, and their components. Since its inception, nf-core has set rigorous standards for documentation, testing, versioning and packaging of workflows, ensuring that pipelines can be "run anywhere" with confidence.

In order to help adhere to the standards, nf-core comes along with nf-core/tools, an open-source toolkit designed to support the Nextflow pipeline ecosystem. These include tools for the creation, testing, and sharing of Nextflow workflows and components. The nf-core tooling is central to all nf-core pipelines, but it can also be used to develop pipelines outside the nf-core community.

The pipelines and the tooling are actively maintained by the nf-core contributors and by the nf-core infrastructure team (supported by the CRG, SciLifeLabs, QBIC, and Seqera). This infrastructure provides everything: from pipeline templates to management of nf-core components, ensuring consistency and high quality across projects.

In this talk, we’ll give a short introduction to nf-core and how nf-core/tools supports both pipeline developers and end users, helping the community build reliable and reusable workflows.
