This disclosure describes methods, apparatuses, and systems for providing visualizations of workflows. Data associated with successes and failures of individual components of workflows can be collected and aggregated to provide an overview of the operation of workflows, as well as allowing a software developer to troubleshoot operations of the workflow. Status indications of steps can be visualized in a graphical user interface (GUI), for example, and faults can be identified and presented in the GUI. By aggregating workflow data across hundreds, thousands, or even millions of workflows, a user can quickly determine the overall operations of the workflow, as well as areas of the workflow that may need improvement.
