Callstack
Helping teams ship better cross-platform apps, with React, React Native, and Open Source at the core.
We’re Callstack: Open Source contributors, core contributors to React Native, and active members of the community pushing the React Universe forward.
Here you’ll find what we live and breathe every day:
Podcast 🎙️ React Universe On Air, with insights from across the React ecosystem
Event Recordings 🎥 Livestreams, talks, and behind-the-scenes from React Universe Conf & React Conf
Tutorials 📚 Hands-on guides and deep dives into React and React Native
Webinars ⚙️ Technical sessions on building full-stack, cross-platform apps
