PROOF (PRoduction On-ramp for Optimization and Feasibility) is a collection of software designed to help researchers manage and execute WDL (Workflow Description Language) workflows using the Cromwell workflow manager, configured to run on the Fred Hutch cluster. PROOF allows users to:

  • Validate, run, track, troubleshoot, and assess the performance of workflows in one application.
  • Automate all the backend configurations necessary to submit your workflows instantly.
  • Test, refine, and harden your workflows before potentially transitioning to cloud-based infrastructures, all in a no-cost ‘proofing’ environment that enables quick iterations.

PROOF is a collaborative partnership between Scientific Computing and the Office of the Chief Data Officer (OCDO). PROOF is only available on the Fred Hutch network at this time.

PROOF Workbench

PROOF Workbench is the flagship product of the overall PROOF effort. Get your computational workflows up, running, and organized with this web application built in partnership with Fred Hutch researchers. Track multiple workflows simultaneously while caching correct results so you do not have to waste time recreating them.

PROOF Legacy

PROOF Legacy, formerly known as simply PROOF, or Shiny Cromwell, was our first iteration of building the web application that inspired PROOF Workbench. We plan to support PROOF Legacy through the end of 2026, but we encourage PROOF Legacy users to adopt PROOF Workbench. If there are features of PROOF Legacy that you feel are missing from PROOF Workbench, please let us know by sending an email to wilds@fredhutch.org.
