Welcome to Cromwell
Cromwell is an open-source Workflow Management System for bioinformatics. Licensing is BSD 3-Clause.
The Cromwell documentation has a dedicated site.
First time to Cromwell? Get started with Tutorials.
Google LifeSciences is shutting down in July - migrate to GCP Batch
Google is replacing Cloud Life Sciences (sometimes referred to as PAPI) with a next-generation API named GCP Batch https://cloud.google.com/batch/docs/migrate-to-batch-from-cloud-life-sciences.
See documentation on how to migrate to GCP Batch
Community
Thinking about contributing to Cromwell? Get started by reading our Contributor Guide.
Cromwell has a growing ecosystem of community-backed projects to make your experience even better! Check out our Ecosystem page to learn more.
Talk to us: - Join the Cromwell Slack workspace to discuss the Cromwell workflow engine. - Join the OpenWDL Slack workspace to discuss the evolution of the WDL language itself. - More information about WDL is available in that project's repository.
Capabilities and roadmap
Many users today run their WDL workflows in Terra, a managed cloud bioinformatics platform with built-in WDL support provided by Cromwell. See here for a quick-start guide.
Users with specialized needs who wish to install and maintain their own Cromwell instances can download a JAR or Docker image. The development team accepts reproducible bug reports from self-managed instances, but cannot feasibly provide direct support.
Cromwell's backends receive development resources proportional to user demand. The team is actively developing for Google Cloud and Microsoft Azure (see Cromwell on Azure). Maintenance of other backends is primarily community-based.
Cromwell supports the WDL workflow language. Cromwell version 80 and above no longer support CWL.
CWL will be re-introduced at a later date in the Terra platform, using a solution other than Cromwell. See the blog post "Terra’s roadmap to supporting more workflow languages" for details.
