Nitro has become the foundation for some of the most powerful React Native libraries today.

At React Universe Conf 2025, Marc Rousavy (CEO at Margelo, creator of VisionCamera and MMKV) traces the story of Nitro: from its origins in JSI experiments to its role in powering high-performance libraries like react-native-filament, MMKV, and soon VisionCamera.

🔹 Lessons learned from early JSI host objects in MMKV and VisionCamera
🔹 Why boilerplate, threading issues, and crashes led to building Nitro
🔹 How Nitro simplifies bindings with strong typing, thread safety, and code generation (Nitrogen)
🔹 Using Nitro to bridge C++, Swift, and Kotlin seamlessly
🔹 Nitro’s growing ecosystem: Nitro Image, MMKV rewrite, Filament, and more
🔹 What the future holds as VisionCamera is migrated to Nitro

In short, this talk shows how Nitro is shaping the next generation of native modules.
