| Starting Price | Not publicly listed (enterprise quote-based); third-party listings suggest enterprise-level spend | Not fully public; pricing is package/usage based and typically requires sales engagement | Public entry point exists: published pay-as-you-go entry and subscription plans; trial options available |
| Primary Use Case | Enterprises modernizing mainframe/IBM i with phased decoupling and automated service generation | Broad integration + API management across SaaS/on-prem systems, governance-heavy environments | Organizations seeking faster iPaaS onboarding with a broad connector ecosystem and flexible pricing |
