It is closely associated with WDL, ships with the womtool helper, and can run workflows locally, as a server, or against pluggable execution backends. ### Project history The repository was created in 2015, and early releases began that year. The official documentation says Cromwell started life as a WDL engine, with WDL draft-2 as its first language, and later added WDL 1.0 support while continuing to track WDL development. Cromwell's architecture centers on workflow execution backends. The official backend documentation describes included support for Local, HPC schedulers such as SGE, LSF, HTCondor, and Slurm, Google Cloud through Google Batch, GA4GH TES, and AWS Batch beta support. ### Adoption history Broad's README points many users toward Terra, a managed bioinformatics platform with built-in Cromwell support, while self-managed users can download a JAR or Docker image. This split shaped Cromwell's adoption: package managers provide local CLI access, but large production usage often happens through managed or institution-maintained deployments. ### How it is used Users run Cromwell to execute WDL workflows and use womtool for WDL validation and workflow object model tasks. Common deployments range from five-minute local tutorials to persistent server mode, cloud batch backends, and HPC scheduler integrations. ### Why package nerds care For package maintainers, Cromwell is a JVM scientific-workflow package whose command-line distribution wraps a larger service-oriented engine. It matters because reproducible workflow tooling often needs both local executables for validation and stable release artifacts for institutional compute environments. ### Timeline - 2015: Repository created and 0.5 release published. - 2015: Early 0.x releases established Cromwell as a WDL workflow engine. - 2020s: Documentation emphasizes Terra-managed usage, self-managed JAR or Docker deployments, WDL support, and modular backends. ### Related projects - WDL and OpenWDL are the workflow language context for Cromwell. - Terra is a managed platform with built-in Cromwell support. - GA4GH TES, Google Batch, AWS Batch, and HPC schedulers are execution-backend contexts. ### Sources - - - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** cromwell - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Related links - [Source-control packages](https://www.automicvault.com/pkg/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Language runtime packages](https://www.automicvault.com/pkg/language-runtime-packages/) - Matched language runtime, compiler, or interpreter metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [openjdk](https://www.automicvault.com/pkg/brew/openjdk/) - Runtime dependency declared by Homebrew. - [snakemake](https://www.automicvault.com/pkg/brew/snakemake/) - Shares av.db curated category or tags: bioinformatics, cli, science, workflow-management. - [sprocket](https://www.automicvault.com/pkg/brew/sprocket/) - Shares av.db curated category or tags: bioinformatics, cli, science, wdl. - [abpoa](https://www.automicvault.com/pkg/brew/abpoa/) - Shares av.db curated category or tags: bioinformatics, cli, science. - [abricate](https://www.automicvault.com/pkg/brew/abricate/) - Shares av.db curated category or tags: bioinformatics, cli, science. - [abyss](https://www.automicvault.com/pkg/brew/abyss/) - Shares av.db curated category or tags: bioinformatics, cli, science. - [adapterremoval](https://www.automicvault.com/pkg/brew/adapterremoval/) - Shares av.db curated category or tags: bioinformatics, cli, science. - [alevin-fry](https://www.automicvault.com/pkg/brew/alevin-fry/) - Shares av.db curated category or tags: bioinformatics, cli, science. - [any2fasta](https://www.automicvault.com/pkg/brew/any2fasta/) - Shares av.db curated category or tags: bioinformatics, cli, science. - [biodiff](https://www.automicvault.com/pkg/brew/biodiff/) - Local package facts share a topical domain.
