Callstack Incubator

Welcome to Callstack Incubator

This is a place where we're pushing the boundaries of what's possible with React Native.

Areas of Focus

  • Artificial Intelligence: We're building AI-powered tools and intelligent automation for the next generation of mobile applications.
  • Developer Experience: Cross-platform development is great. We want to make you even more productive by bringing new languages to the React Native ecosystem.
  • Performance: There's always room for improvement. We're always looking for ways to make React Native faster and more efficient.
  • New Platforms: React Native is a "learn once, write anywhere" framework. We're working on new platforms to keep that promise.

Motivation

The React Native ecosystem moves fast, and new technologies bring both opportunities and challenges. At Callstack, we're dedicated to pushing technical boundaries and solving hard problems. We build the tools today that you will need tomorrow. ~ Mike Grabowski, CTO
