Prose analysis
ServiceNow is a platform suite; Flow-Like is a portable workflow-app engine.
ServiceNow is compelling when the enterprise already runs service management, IT operations, HR, risk, or CRM workflows in the Now Platform. Its strength is platform breadth, governance, and specialized workflow applications.
Flow-Like is a better fit when the team wants a smaller, portable unit of software: a typed workflow plus data handling, AI, and UI that can be self-hosted or run locally without adopting a broad enterprise SaaS platform as the system of record.
