React Native's New Architecture — Fabric renderer and the JSI bridge replacement — shipped as stable in 0.73. Combined with Expo's managed workflow reaching full maturity, the story for cross-platform mobile in 2025 is the strongest it has ever been.
What the New Architecture changes
The old asynchronous JavaScript bridge is gone. JSI gives JavaScript direct synchronous access to native modules. UI updates no longer have to wait for a round-trip across the bridge, eliminating the most common source of frame drops in complex scroll views and animations.
Expo in production
EAS Build, EAS Submit, and EAS Update form a complete CI/CD pipeline for mobile without managing your own Mac build servers. Over-the-air updates through Expo Updates let you ship bug fixes to production in minutes rather than waiting for App Store review.
On our last five mobile projects we shipped iOS and Android from a single codebase with feature parity. Estimated time savings versus maintaining two native codebases: 40–55%.
