Reproducibility in computational research is vital for efficient collaboration, verifying results and ensuring transparency. Yet it remains challenging due to complex workflows, inconsistent data management and the reliance on specific software environments. SciWIn Client is a command-line tool designed to easily create, record, annotate and execute computational workflows. SciWIn Client enables researchers to interactively use intuitive commands to keep track of tasks such as as data-extraction, -cleaning, -transformation, -analysis, -visualization and computational simulation. Automated and standardised workflows minimise sources of error and support transparent and reproducible Open Science.
