BLAST FROM THE PAST

React Universe Conf is brought to you by Callstack, a software consultancy that helps companies ship faster and scale smarter with React and React Native.

Founded just months after React Native went open source, Callstack has been part of this ecosystem since the beginning and has been shaping it ever since. Over 200 engineers work with enterprises and small businesses alike to build high-performing apps for every platform - iOS, Android, tvOS, visionOS, web, and beyond. We build in the React Universe: one full-stack, cross-platform codebase that runs everywhere - hence the name of this conference.
