Case Study: a leading Indian private sector bank reclaims frontend ownership with FlutterFlow Enterprise

a leading Indian private sector bank migrates 50M users with FlutterFlow

A leading Indian private sector bank faced significant challenges due to vendor lock-in with its legacy digital banking platform. This dependency slowed innovation, limited ownership of the frontend code, and constrained performance for its app with over 50 million downloads. The bank partnered with FlutterFlow, using FlutterFlow Enterprise, to break this dependency and modernize its large-scale application without disrupting its millions of users.

The solution involved using FlutterFlow Enterprise as a foundation to rapidly rebuild and migrate high-impact user journeys in phases. This allowed the bank to reclaim full ownership of its UI and release cycles. As a result, FlutterFlow helped accelerate feature delivery from weeks to days while maintaining enterprise-scale performance for over 13 million monthly active users.
