Celebrate the world’s young tech innovators

Coolest Projects International is a world-leading showcase for young innovators who make stuff with technology.

The registration form is simple, and you should complete it with the adult who will accompany you to the event.

Your project does not need to be finished for you to register — an idea or the beginnings of a creation is enough!

  • All projects are encouraged, in any programming language and with any hardware
  • Your project can be as simple or as complex as you like
  • Works-in-progress are welcome
  • Participate by yourself, or as part of a team of up to five

Your project could win an award in different categories, from games or mobile apps, to advanced programming or 3D design. Find out more about the categories.

If there is another Coolest Projects event you want to attend this year, you can participate with the same project!
