We build, maintain and contribute to the most popular Open Source libraries. We contribute to the React and React Native ecosystems every day improving developer experience for everyone.
We contribute to the React Native community on a daily basis. We comment and discuss proposals, suggest improvements and maintain some of the modules that were extracted as a part of Lean Core effort. Every month our team works closely with other members of the React Native Community to cut a new framework release and put it out there for developers to use. Check the latest React Native releases.
Releasing a project as open source means that any developer is free to use, modify or distribute your work. Open Source libraries are available and configurable so you can easily create your own custom elements.
At Callstack we advocate code and knowledge sharing! We love Open Source so much that we offer our developers a budget for their Open Source work.
We work closely with Facebook, Microsoft and Expo on Open Source projects to support the community. Take a look at some of our best-known projects.
We hold events such as conferences, meetups or hackathons to talk about our projects and to learn from one another! We are proud organizers of the biggest react native conference in the world (and the first conference in Europe) which focuses exclusively on React Native. It’s a unique place for sharing expertise and learning from the top industry leaders.
Since 2017 we bring the React Native community together to discuss technical topics and network with fellow developers. Each year the conference gathers thousands of React Native and React developers from all over the world.
The React Native Show is a React Native podcast series powered by Callstack. There are already already quite a few episodes dedicated to different topics such as React Navigation, Hermes, React Native for Windows or brownfield development.
Each episode focuses on specific aspects of the React Native ecosystem and hosts expert guests who are core contributors, owners of the Open Source libraries or top specialists and leading authorities on React Native. Check the latest episode:
