nf-metro playground
Where do you want to start?
Build a publishable pipeline map without installing anything. Your work stays in this browser unless you share or download it.
Report a bug
This opens a pre-filled GitHub issue in a new tab with your current map, options, and description. You review and submit it there (a GitHub account and sign-in are required).
Import Nextflow DAG
Paste a Nextflow -with-dag Mermaid file to convert it into a starting metro map. Generate one withnextflow run <pipeline> -preview -with-dag dag.mmd— see theNextflow import guide.
Attach a logo
Embeds the image directly into the%%metro logo: directive as inline data, so it travels with the map text. The playground runs entirely in your browser and cannot read a logo file from your computer's disk by path.
