Rewrites are back on the table. AI can help teams move faster, and more companies will use it to migrate mobile apps: native to React Native, React Native to native, or toward whatever comes next. But in large production systems, code is only one part of migration. When the app is live, business-critical, used by a large audience, and changing every week, every analytics event, edge case, release path, and small behavior matters.

Using a real-world, anonymized case study, this talk compares Greenfield and Brownfield approaches to modernizing a live app without disrupting users or the business. React Native is the concrete example, but the focus is decision-making: continuity, observability, analytics reliability, delivery velocity, organizational constraints, cost, and risk over time.

You’ll see real-world data points, Brownfield architecture, validation through POCs and production reference screens, and a practical mental model for choosing the safest road to the same destination.

The React Native ecosystem is more than just a framework. It is the people building the libraries, the tooling, and the invisible infrastructure that make modern mobile apps possible. This panel looks at the projects developers rely on every day, the challenges of keeping them maintained and evolving, and the community effort required to keep React Native moving forward. We’ll discuss what’s changing in the ecosystem, which tools are becoming essential, how maintainers decide where to invest their time, and what developers should know to build with confidence today and beyond.
