The all-inclusive hackathon for software developers, engineers, and tinkerers of all stripes.

Welcome to the Global Developer Challenge 2020! You will have one week to plan, design, and develop any software project and showcase it to other committed Challengers. 

You may develop anything—Alexa skills, simple games, APIs/frameworks, machine learning solutions, websites or web apps, statistical simulations, mobile applications, automated scripts, small lifehacks, or anything else. We encourage you to explore ideas you are genuinely passionate about and build things you might not feel like you can in other hackathons.

Have an idea for a practical, problem-solving hack? That's great! 

Want to just explore a concept you find fun and engaging? That's perfectly fine too!

Our aim is to stimulate creativity and skill development among the developer community with a fun, week-long sprint. Are you up for the Challenge?
