ravanan is a [Common Workflow Language (CWL)](https://www.commonwl.org/) implementation that is powered by [GNU Guix](https://guix.gnu.org/) and provides strong reproducibility guarantees. ravanan provides strong foolproof caching so you never run the same steps of your workflow twice, nor do you have to keep track of which steps were run and with what parameters: ravanan remembers everything for you. ravanan captures logs from every step of your workflow so you can always trace back in case of job failures.

ravanan currently runs on single machines and on slurm via its [API](https://slurm.schedmd.com/rest_api.html). Other HPC backends will be implemented in the future based on demand.
