Science Capsule is free open source software that allows researchers to automatically capture their end-to-end workflows including the scripts, data, and execution environment. Science Capsule monitors the workflow environment to capture the provenance at runtime. It provides a timeline view and a web interface to represent the workflow and data life cycle, and the associated provenance information. Science Capsule also leverages container technologies toprovide a lightweight, executable package of the scripts and required dependencies, ensuring portability and reproducibility.
