Intland Retina is a scalable, enterprise-ready platform with full (scaled) Agile support, a user-friendly experience, and full customizability to match your complex workflows. Retina comes with out-of-the-box integrations and a mobile-native UI to give your teams the speed, scalability, and high availability they need.
Jama Connect, on the other hand, is focused on requirements management, risk management, and reviews, with limited capabilities around test management. It lacks the Agile project management, planning, and source code management functionality that most teams require.
