React Native apps are bigger and more complex than ever. At Callstack, we've built Rock (open, modular, self-hosted, and incrementally adoptable framework for React Native) to help teams scale, migrate, and deliver faster. React Native just turned 10, and its adoption has followed a familiar curve, from early startups to scale-ups, mainstream apps, and finally large enterprises making their move. The Community CLI has long been the backbone of this ecosystem, but as React Native evolved, embracing Expo, modularity, and framework-driven development, we realized the needs of today's teams go far beyond what the CLI alone can offer. In this talk, we'll share how we got here, why frameworks are the future of React Native, and how our new open-source framework can help teams migrate smoothly, unify tooling, and accelerate delivery.
